Abstract:

LIGHTCELL ims at developing innovative architectures for thin-film photovoltaics (TF-PV) utilizing inorganic, environmentally stable (Sb2X3, X=S, Se) materials and sustainable fabrication processes with reduced energy consumption. Sb2X3 can be synthesized in a quasi-one-dimensional (quasi-1D) form, addressing the main factors limiting the efficiency of TF-PV, i.e., recombination of the photogenerated carriers at the grain boundaries. A multidisciplinary consortium of academic and industrial partners aims at developing a scalable technology of sustainable, cost-efficient, and lightweight PV. For faster feedback loop to synthesis, a new tool for the rapid and non-destructive mapping of 2D and 3D crystallographic orientation of quasi-1D materials will be developed. The PV technology developed in LIGHTCELL will be validated in demonstrators by the industrial partners, targeting lightweight building-integrated PV applications, contributing to sustainable green energy production.

Abstract:

The scope of the project is to increase the innovation capacity and competitiveness of the coordinating enterprise S.C. OPTOELECTRONICA-2001 SA, by developing its offer of technologies and products adapted to the market requirements to streamline the maintenance of constructions that have large surface windows. The economic agent develops technology for coating windows with antibacterial and self-cleaning properties nanostructured layers by assimilating the RDI results of the partners, the National Institute of Materials Physics and the Institute of Solid Mechanics of the Romanian Academy.

The objectives of the project are: obtaining glass prototype (window surface with nanostructured layers) with antibacterial and self-cleaning properties; obtaining equipment prototype for deposition (printing) of nanostructured layers (TiO2) on glass substrate with surface dimensions equivalent to A2 format; obtaining prototype technology for coating windows with nanostructured layers; connecting applied research and technological progress in Romania to the evolution and requirements of the socio-economic environment; increasing the innovation capacity of the applicant enterprise, through the development of new technology and product, estimated to have the potential for commercial exploitation on the domestic and international markets.

TiO2 coatings will be obtained through an innovative technology patented by INCDFM through which the morphology of the TiO2 layer can be modified to improve the wetting properties of the surface and therefore the self-cleaning efficiency, and to increase the antibacterial activity that depends mainly on surface chemistry and structure. This technology has an important advantage in the economy of producing TiO2 coatings on an industrial scale, the technological processes developed requiring temperatures lower than 150°C and for very short times (less than 15 min).

Abstract:

The perovskite solar cells (PSC) have attracted a considerable interest in photovoltaics community, showing a very fast development in terms of power conversion efficiency (PCE), reaching now values over 25% certified PCE in not stabilized small area samples, proving that they can become real competitors to commonly used solar-cell materials (e.g based on Si). Not only the remarkably large PCE is an important asset, but also the low production costs makes the PSCs very attractive for the solar cell technology, as solution processing techniques are typically employed. In addition, they can be hosted by a long range of flexible substrates, pushing further the record for power per weight and implicitly their utility. However, while the high PCE values and the low production costs are important advantages for PSC, the real challenges to overcome prior of industrial production are their stability in time, reliability and reproducibility of the performance as well as environmental issues raised by the use of toxic elements/solvents. These are well known problems for the small area standard and inverted PSCs, produced by spin-coating in research laboratories and inherently remain the same when envisaged is the fabrication of large area devices. The project addresses these issues starting from the premise that coherent experimental and theoretical studies should be done using from the start cheap deposition techniques applicable on large areas (printing and sputtering). Beside allowing the scaling up, such techniques can be better controlled offering a better homogeneity in deposition than the spin-coating method. The present project includes fundamental and applicative research aiming to achieve both scientific and practical goals. The overall aims/objectives of the project are: A) to develop efficient, stable, reproducible standard and inverted perovskite solar cells and photovoltaic modules fabricated with affordable large area and environmental friendly technologies. It is expected that by developing low cost and stable photovoltaic panels with optimized efficiency the use of such devices in public and private buildings will be boosted, contributing thus to increasing the share of renewable energy in energy balance in Romania and Donor States; B) to strengthen the knowledge base concerning the application of environmental technology; new knowledge will be acquired regarding how PSCs can be optimized for large scale applications and how can they be fabricated using environmentally friendly technologies with low carbon footprint. Specific objectives to be achieved during the project are: O1 - understand the physical working principles of perovskite solar cells and find solutions to increase and stabilize the PCE while enlarging the area of the cells; O2 – reduce the amount of costly materials and toxic solvents used in the fabrication process of both standard and inverted PSC structures with other inexpensive and environmental friendly; O3 - stabilize the PCE performance of PSC via compositional engineering and proper replacements including the selective contacts; O4 - enhance the charge collection efficiency by optimizing interfaces between the layers in the cell; O5 - develop cheap large area fabrication technologies (printing and sputtering) for all the component layers in PSCs, standard and inverted structures; O6 - obtain efficient large area encapsulated PSCs and photovoltaic modules with PCE over 15%. The starting TRL is 3 and the envisaged TRL is 6, meaning that fully operational photovoltaic modules will be manufactured and tested in relevant industrial environment with the help of the SME partner.

The consortium is composed by 5 partners: National Institute of Materials Physics (NIMP), Horia Hulubei National Institute for R&D in Physics and Nuclear Engineering (IFIN-HH), and Tritech Group (WATTROM), a SME as end-user, all from Romania; Oslo University (UiO) from Norway, and Reykjavik University (RU) from Iceland.

Abstract:

Edge computing requires highly energy efficient microprocessor units (MCU) with embedded non-volatile memories (eNVM) to process data at the source that is the IoT sensor node. eFLASH technology is limited by low write speed, high power and low endurance. Alternative fast, low power and high endurance eNVM could greatly enhance energy efficiency and allowflexibility for finer grain of logic and memory. FeRAM has the highest endurance of all emerging NVMs. However, perovskite-based eFeRAM is incompatible with Si CMOS, does not easily scale and has manufacturability and cost issues.

3eFERRO introduces new ferroelectric material Hf(Zr)O2 to make FeRAM competitive NVM candidate for IoT. HfO2 compatibility with Si processing will facilitate integration, improve manufacturability and allow better scaling. Different cell architectures based on capacitors or ferroelectric FETs will give unprecedented flexibility for “fine-grained” logic –in-memory (LiM) circuits, which allows data storage close to logic circuits, reduces energy cost of data transfer and allowssmart gating for “normally-off” computing.

The project is built around four objectives: i) Optimization of Materials, ii) LiM design & architecture, iii) Integration of Hf(Zr)O2-based NVM arrays, iv) Memory test & validation & benchmarking. The work calls on the full spectrum of expertise from advanced materials synthesis and characterization, processing, design and integration and benchmarking to make substantial progress towards a truly disruptive energy efficient memory and logic technology.

A team of 8 partners, including a major European semiconductor company, the leader in the field of ferroelectric HfO2 and a large technology laboratory, originating from 5 EU states, will join forces to deliver experimental demonstrators creating the opportunity for the EU industry to establish a dominant position in IoT innovative components market and make an impact on the future roadmap for embedded systems and applications.

Abstract:

Dielectrics are insulating materials that have been the workhorse in computing and electronics. Since the invention of the transistor and the integrated circuit the modern complementary metal oxide-semiconductor (CMOS) technology heavily relied on rigid SiO2/Si substrates and the relentless downscaling of the size of the transistor has been the core driver for the information revolution. However, to meet the increasing need for miniaturization, low power function and portability in both the civilian and military sector, discrete electronic components, such as capacitors, resistors, inductors and transistors should be replaced by embedded circuitry. An important roadblock in the development of energy storage and memory/switching devices with increased efficiency and range of operation is the rather low dielectric permitivity and carrier mobilities of organic polymer materials. The four research teams of the present consortium, led by A. Rotaru (USV, Suceava), L. Mitoseriu (UAIC, Iasi), I. Pintilie (NIMP, Bucharest) and A. Marcu (INFLPR, Bucharest), propose to demonstrate proof concept of manufacturable nanocrystal film structures with a high dielectric permitivity with direct applications in high energy density storage and low-voltage modulated field effect transistors and logic devices. In addressing these challenges we will use complementary expertise in materials synthesis and characterization, device design and testing with the potential of disruptive innovation in flexible electronics.

Abstract:

The main objective of the project is to obtain ferroelectric materials with controlled electronic properties at the same level as this properties are controlled in Si. This will be realized by hetero-valent doping, correlated with stress engineering and band gap engineering without affecting, as much as possible, the ferroelectric properties. The main objective is complex and ambitious because, up to date, there was no experimental demonstration that it possible to obtain n or/and p type conduction in epitaxial ferroelectrics. The successful achievement of this objective will open a new domain, that of ferroelectric electronics or ferrotronics, by producing electronic devices of p-n homo-junction type or junction transistors with ferroelectric materials. Two types of materials are envisaged, namely lead titanate-zirconate (PZT with tetragonal structure and a mixed bismuth ferrite (BFO) with bismuth chromit (BCO). In the first case the heterovalent doping will be studied on Pb or Zr/Ti sites with the aim to obtain n and p type conduction. The final goal is to produce a p-n homo-junction based on epitaxial PZT films. In the second case band gap engineering will be tested by varying the Fe/Cr content, and the dominant conduction mechanism will be identified, the goal being to use the material in photovoltaic applications. The activities will contain: theoretical studies regarding the relation between dopants, electronic properties and the ferroelectricity, including self-doping effects or electrostatic doping; target preparation for deposition of thin films; epitaxial growth of the film; characterization activities of the structure and physical properties. Not only classic doping in the target is envisaged but also doping during the epitaxial growth. The consortium is composed of 4 teams from three different institutions, including a number of 14 young researchers full time equivalent.

Project website: http://optim-prv.nipne.ro/index.php

Abstract:

The project proposes a new methodology for screening, prediction and validation of photoactive perovskite materials using machine learning techniques (ML). In the past few years, solar cells based on hybrid perovskite materials have shown impressive values of photoconversion efficiencies (PCEs), to date reaching 25.2%, with options for further enhancement. However, due to the huge number of possible structural and compositional configurations, optimizing the perovskite materials for stability and solar cell PCE by exhaustive numerical calculations or large scale synthesis is not feasible. Instead, the ML techniques can provide the necessary framework for a guided search. Using high throughput density functional theory (DFT) calculations, a database containing opto-electronic properties of interest shall be first assembled. Then, the ML scheme shall be implemented using artificial neural networks (ANNs), which already provided successful predictions in other condensed matter systems. They will primarily use the theoretical data as well as feedback from experiments. The selected candidates shall be synthesized and perovskite solar cells shall be fabricated as final products. The aim is to optimize the absorption spectra of the perovskite materials in order to increase the solar cell PCE and to enhance their stability. The coordinator team (NIPNE) will be focused on the development of the DFT-ML scheme, based on prior experience with first-principles calculations and ANN based methods for the prediction of the electronic gaps. The partner team (NIMP) will perform the synthesis of perovskite materials and fabrication of PSCs, based on extensive expertise accumulated during the PERPHECT project, where record PCEs were achieved. Relating two key elements (ML techniques and perovskite materials) the project is expected to have a large impact in material engineering and can reshape the current approaches for investigating new materials.

Project website: https://infim.ro/project/solar-mini-module-with-perovskite-solar-cells/

Abstract:

In the last decade, a new generation of solar cells arise remarkably, the hybrid perovskite solar cells (HPSCs, or simply PSCs). They cumulate exceptional intrinsic photophysical properties with manufacturing versatility and low-cost precursors materials, therefore present huge potential for large-area production on an industrial scale.

This project, brings previous research conducted by our group, in the field of perovskite solar cells, closer to commercial applications by fabricating large-area perovskite solar cells and integrating them into functional solar modules. The Solar-PVK project aims to develop efficient (PCE>10%), large-area PSCs, with an active area exceeding 1 cm2, using low-cost solution deposition technologies. These devices will be connected together and encapsulated in a sealing box fabricated in-house, to assembly a prototype of a functional solar module. This solar module will be integrated into a solar portable charger, able to power for example a mobile phone, in case of emergency situations or off-grid low power applications.

The novelty consists in the topic of solar perovskite hybrid cells, which is new internationally and at the national level; no other research institution in Romania has reported the fabrication of PSCs. The idea of the project is bold and contains significant risk elements but promises of high reward if the difficulties could be surmounted.

Fabricating a solar charger based on hybrid perovskite solar cells presents the highest degree of novelty.

Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.

Abstract:

The ambitious goal of PEROFER proposal is to design new approaches for the synthesis of hybrid organic-inorganic perovskite-type materials with possible ferroelectric properties for photovoltaic applications. The advantages of hybrid organic-inorganic perovskite (HOIP) are: i) their low cost, ii) use of Earth-abundant and available elements, and iii) low-temperature processing synthetic routes through which they can be produced. Nevertheless, before commercialization of HOIP for photovoltaic technology there are some scientific and technical drawbacks which must be overcome: i) poor reproducibility of the HOIP materials; ii) lack of uniformity of the perovskite layers; iii) rapid degradation in moist environments (especially water); iv) lack of long-term stability of perovskite solar cells; v) suffers from bandgap larger than the ideal; iv) the use of highly toxic and carcinogenic Pb element with high environmental impact.

To give a chance to hybrid organic-inorganic perovskite onto the market, the development of very efficient, cost-effective and environmental friendly synthesis method of HOIP is highly desired.

The challenges of PEROFER proposal are original and innovative, and require scientific breakthroughs in fundamental phenomena and significant technological developments.

Abstract:

The aim of this project is to propose a new approach for investigating the influence of the extrinsic versus intrinsic contributions on the electrical behaviour in the compositionally modified-BaTiO3-based systems. Therefore, aliovalently and homovalently doped-BaTiO3 ceramics, with certain fixed dopant/solute concentrations and with a wide range of grain sizes, from microscale downward to nanoscale, will be prepared from powders synthesized by various variants of the sol-gel method and consolidated by using alternative sintering techniques (conventional and spark plasma sintering). In this way, it is envisaged to adjust the semiconducting-insulating behaviour in multiscale Ce3+ doped-BaTiO3 and to tailor ferroelectric-relaxor crossover in multiscale BaTiO3 ceramics with Hf4+ additions. Another goal consists in enhancing ferroelectricity in dense Ce3+ doped-BaTiO3 (BCT) thin films and 1D nanostructures. The investigation of Ce3+ doped-BaTiO3 products with similar composition, but corresponding to dissimilar dimensionalities (1D, 2D and 3D), will allow elucidate and to understand the role of the restrictive geometries on the dielectric/ferroelectric/piezoelectric response. For this reason, multilayer thin films will be prepared by chemical solution deposition, while infiltration of negative templates will be used to elaborate 1D nanostructured wires/tubes. All these objectives involve a complex physico-chemical and functional characterization by using modern and complementary techniques.

Abstract:

The specific project proposed here is embedded as part of the RD50 efforts, in the subgroup Defect and Material Characterization. The director of the present project is the leader of the NIMP team involved in the CERN-RD50 and the convener of this research line within the RD50 collaboration. The general objective of the proposed project is to improve the radiation hardness of different types of silicon sensors to be used for ATLAS and CMS Strip Tracker upgrade (single pads, pixel and strips, LGAD and HVCMOS) built on p-type standard float zone (STFZ), epitaxial (EPI) and defect engineered Si. Since in p-type (Boron doped) Si the most obvious change observed in the electrical performance is the loose of the doping due to irradiation, thought to be caused mainly because of forming the BiOi trapping centre, the project addresses two defect engineering approaches: (i) intentionally adding Carbon impurity in the bulk of boron doped Si, with the aim of changing the usual defect formation path during irradiation, by slowing down this way the boron removal while creating other carbon containing defects with much lower impact on the electrical characteristics of the sensors at their operation temperature; (ii) to dope the silicon with Gallium instead of Boron. The project is thus focusing on investigation, analyses and modelling of the defect generation and kinetics induced by irradiation in standard Boron doped and/or Carbon co-doped/implanted Si as well as in Gallium doped silicon. The specific investigation techniques that will be employed (Deep Level Transient Spectroscopy, Thermally Stimulated Current and Thermally Dielectric Relaxation Current methods, High Resolution Transmission Electron Microscopy, I-V and C-V electrical characterization) will deliver defect input parameters for developing theoretical models able to calculate (numerically and in some cases even analytically) and predict the impact of radiation induced defects on the electrical properties of different types of Si particle sensors in various operation scenarios as well as the defect generation and kinetics in the presence of different types of impurities. The ultimate goal of the project is to provide a comprehensive knowledge of radiation induced defects and their generation mechanisms which will be finally used to improve the radiation hardness of pad, LGAD and HVCMOS devices. Based on the mentioned defect engineering studies, viable theoretical models describing and predicting the generation and evolution of the defects in the presence of intentionally added impurities will be achievable. This way it will be possible to develop during the project the strategy for optimizing the impurity content which would finally reveal the required performance of each of the envisaged p-type silicon sensors. These studies will start on already fabricated or planned to be produced in the next months, pads, LGADs and HVCMOS sensors. At the beginning of the 3rd project year, optimized defect engineered p-type sensors will be produced within the RD50 collaboration, based on the project results obtained until then. The new run of experiments on optimized sensors will be performed during the last project year and it is expected that they will fully validate the predictions evolved from modelling & experimental results performed before. If this will not be the case and it will be some place for further improvements, the obtained results will be accounted for correcting the previous developed models and provide new optimization solutions to be considered beyond the present project.

Abstract:

The project is proposing to develop a new generation of pyroelectric detectors based on wide gap polar semiconductor materials (e.g. AlN, ZnO) able to withstand high operating temperatures. The innovative aspects will go further beyond the state of the art by proposing multilayer structures based on nitrides (AlN, GaN, etc.) and ZnO-ferroelectric structures with the aim to enhance the sensitivity as much as possible at elevated temperatures. Specific innovative aspects can result also from packaging solutions, electronic for signal processing, etc. The detectors are primarily designated for internal combustion and jet engines used in automobile and airplane industries. The aim is to increase the lifetime of the engines, their safety and to optimize the fuel consumption with reduction of green house gases emissions. The expected impact is very high considering the share of the two industries at EU level and worldwide.

Abstract:

The main objective of the project is to manufacture transparent field effect transistors with superior performances, based on aluminum nitride gate dielectrics. Although aluminum nitride is a very promising material for such type of applications, its use as gate dielectric in transparent transistors is an international novelty. Therefore, this project can generate, by its implementation, a significant impact to the development of transparent electronics. The project proposal will entail complex and fluid research activities, from the synthesis of materials and their characterization in view of optimization, to the fabrication of high performing devices on both rigid and flexible substrates. In order to achieve transistors with an functional response superior to the one of the devices used currently in transparent electronics, the project team will employ a series of optimization solutions (testing new geometries, post-fabrication thermal treatments and various encapsulation solutions). Last but not least, the project will represent a great opportunity for the young project team to form a strong scientific nucleus, which, by using the complex infrastructure of the host institution, will be able to contribute to the progress of micro-nano-electronics, on both nationally and internationally level.

Project website: http://www.infim.ro/projects/optimized-pyroelectric-materials-through-polarization-gradient-concept-and-experimental

Abstract:

The project aims to develop materials with optimized pyroelectric properties using the polarization gradient concept and develop integral pyroelectric detectors for the near infrared (700 nm) to THz (≤100 µm) wavelengths range. These detectors have potential application also in the detection of high power or high energy laser beams (e.g. the lasers of ELI-NP project). The materials to be used in this project are ferroelectrics with a perovskite structure such as Pb(Zr,Ti)O3 (PZT) or (Ba,Sr)TiO3 (BST) due to the fact that the transition temperatures can be modified by changing the Zr or Sr content. These materials will be combined in structures of multilayers with gradient in concentration and polarization in order to increase the figure of merit M given by the ratio between the pyroelectric coefficient p and the dielectric constant ε (M=p/ε).

The present project proposes a novel way of increasing the merit figure M by increasing the pyroelectric coefficient. This can be achieved by developing materials that exhibit a concentration gradient in the direction of the polarization, which introduces a succession of phase transitions at different temperatures, leading to a more abrupt variation of the polarization with the temperature and thus to a larger pyroelectric coefficient.

Another effect to turn to account is the temperature variation of the dielectric constant which can contribute to further increase the total pyroelectric coefficient. The temperature variation of ε can contribute to the pyroelectric signal if an electric field is applied to the ferroelectric material in order to maintain a stable polarization state, thus averting possible signal variations caused by the ambient temperature conditions.

The materials with gradient in concentration and polarization will be realized in bulk form, as ceramic wafers (25 mm minimum diameter and 6 mm thickness) by using the spark plasma sintering (SPS). Alternately, the ceramic technology coupled with classical sintering, or hot press, can be used. The sintering conditions will be optimized in order to obtain the best p/ε ratio. The selected material will then be used to build the active elements for the pyroelectric detection. In this respect, metallic electrodes will be deposited and one of them will be blackened in order to ensure a better absorbtion of the incident electromagnetic radiation. A novel approach is that carbon nanotubes are to be used for the blackening. This way the absorbtion coeficient can be increased close to 1. The active element will then be used to create pyroelectric detectors, including the electronics for signal processing and the sofware needed for PC display. Beside the mentioned ceramic materials, epitaxial multilayered structures with gradient in concentration and polarization will be realized and their pyroelectric detection properties will be investigated as well during the project.

The consortium is formed by 3 partners: coordinator of the project –CO is a national institute with experience in ceramic materials and pyroelectric detection; one university –P1 with experience in preparation of ceramic powders; one company –P2 specialized in signal procesing and different types of electrical measurements. CO and P1 will develop the active element for the pyroelectric detection and P2 will develop and test the experimental model of the system for pyroelectric detection including all the electronics and the sofware needed for the different types of applications for which the pyroelectric detector is developed by CO and P2: automatizations, non-contact measurements of temperature or monitoring of the high power/energy laser beams. The ultimate goals are to obtain: a technological process for obtaining the active element of pyroelectric detection, as well as two experimental models, one for the Pyroelectric Detector and one for a Pyroelectric Detection System used to detect high intensity laser beams.

Project website: http://www.infim.ro/projects/effect-interfaces-charge-transport-ferroelectricmultiferroic-heterostructures

Abstract:

The main objective of the project is to perform a detailed study of interfaces and their effect on the charge transport properties in a number of well defined artificial multiferroic structures. Charge transport is beneficial in some cases, for example in tunnel junctions, but can be detrimental in other cases, as for example devices based on magnetoelectric effect or in capacitor like structures. In all cases, at least the interfaces with the metallic electrodes are involved in charge transport, but other interfaces can be also involved if multilayer structures are used. The study will be performed on thin films and/or nanostructures, therefore a significant influence of interfaces on the electronic and ionic charge transport is expected. The start will be from simple capacitor-like structures, to elucidate the problem of electrode interfaces in the case of various ferroic oxides. Further on charge transport in relation with interfaces will be studied in mode complex, multilayer structures with possible applications in tunel junctions, diodes or field effect devices.

The project involves 6 research teams from 2 host institutions, one of which is the National Institute of Materials Physics from Bucharest-Magurele, and the other one is the Alexandru Ioan Cuza University (UAIC) from Iassy. The composition of the teams is a mixes experienced researchers with excellent track records regarding preparation, characterization and modelling of advanced multifunctional materials including oxides, and young scientists at the beginning of their carriers. Some 12 PhD thesis are expected to start during the project. The project is expected to have a major impact not only at the basic science level, reflected by publications in high ranking journals, but also at the level of applied research, as for example manipulation of charge transport through designing specific interfaces or developement of new oxide architectures for ferroelectric field effect controlled of spin currents.

Abstract:

The aim of the project is to identify both the structure of the electrically active defects responsible for the electrical properties of the irradiated silicon diodes and the possible reactions with different impurities in the material. The identification of the main defects responsible for radiation tolerance of silicon sensors as well as their formation kinetics is of crucial importance for further developments of ultra radiation hard silicon material and it is thought that the understanding of their generation and kinetics in the presence of different kind of impurities inside the bulk of material represents the key strategy for this purpose. The proposed project aims at a specific solution of this problem, initiating systematic studies regarding the identification of the chemical structure of the harmful and of the beneficial defects in defect engineered silicon (Si with different content of O and C impurities). The generation of point and cluster related defects will be scanned by performing irradiation with only one type of particles (electrons with energies between 1 MeV and 30 MeV). Three kinds of defects investigations will be performed during the project: 1) Analysis of electrically active defects by means of DLTS and TSC methods; 2) Studies for defect identification by Electron Paramagnetic Resonance (EPR, ENDOR) methods, 3) Microstructural investigation of the extended and clustered defects by High Resolution-Transmission Electron Microscopy (HRTEM).

Abstract:

The aim of this project is the analysis of wide band gap semiconductor (WBS) thin films by use of non-destructive characterization techniques: ellipsometry, XRD and luminescence. These materials have existing or potential applications in optics and/or electronics. WBS thin films will be obtained by use of different thin films growth methods: pulsed laser deposition, magnetron sputtering, sol-gel and direct growth from colloidal suspension. The influence of defects and impurities on optical, electrical and electronic properties of such materials will be analyzed. The results from presented optical studies will be verified by conventional electrical measurements and structural analysis by electronic microscopy.

The project is focused on 3 types of wide band gap semiconductors: zinc oxide (ZnO) pure or doped with different elements; zinc nitride (Zn3N2) and the intermediary phases during controlled oxidation; and aluminum indium nitride (AlxIn1-xN) pure and doped with Zn. One objective is to grow and to characterize the n-type semiconductors with reproducible properties.

The estimated results will bring new insights regarding the physics phenomena involved in the growth process and the material properties, essential for obtaining viable results. In addition, special activities will be included in the project concerning the correlation between the fundamental knowledge and practical necessities of electronics, and the standardization of the growth of thin films below 200C.

Abstract:

The perovskites, having general formula ABO3, with A and B cations of different valences, are multifunctional materials. Depending on the composition they can behave very differently, having properties specific to metals, dielectrics, ferroelectrics, ferro(ferri)magnetics or super- and semiconductors. Most of these materials are inorganic, as for example the well-known ferroelectrics BaTiO3 or PbTiO3. Other perovskites can be hybrid, if the cation A is replaced with an organic radical. This is the case for halide perovskite compounds (CH3NH3PbX), with X=Br, Cl, I, found recently to possess excellent light absorbing properties in the visible-near infrared spectrum. The use of these materials in solar cells had led to a rapid increased of the photovoltaic conversion efficiency (PCE) in the last year up to about 15 %. The typical solar cell is including a transparent electrode (ITO or FTO, both quite expensive and with deficient materials), a TiO2 layer as electron transporter, a halide perovskite as light absorber, a hole transporter (e.g. spiro-OMeTAD), and a counter electrode (e.g. Ag). All these layers can be deposited by low cost technologies. The combination of the relatively high PCE with the low cost technologies makes this type of hybrid photovoltaic solar cell very attractive for future development.

The main objective of the project is to develop perovskite-based photovoltaic devices towards “all perovskite” solar cells with power conversion efficiencies approaching 20% and fabricated with affordable, environmental friendly materials and technologies. The specific objectives are: 1) to understand the mechanisms behind the high efficiency obtained using a hybrid halide perovskite as visible-light absorber; 2) to increase the PCE by using oxide perovskites with ferroelectric properties (e.g. BaTiO3) as carrier transporter; 3) to develop flexible solar cells by replacing the ITO/FTO transparent electrode with metallic nanowebs. The project goals go well beyond the present state-of-the art by trying to integrate a ferroelectric layer as carrier transporter, taking advantage of the presence of its spontaneous polarization, and by replacing the ITO or FTO electrodes with a metallic nanoweb offering more robustness and flexibility.

The final goal is to have an efficient structure with transparent electrodes on both sides, able to collect not only the sun-light but also the light coming from the artificial sources used, especially during the winter, inside office buildings or large malls. Therefore, the project has a very high innovative potential. On the other hand, in-depth studies will be performed in order to understand the physical phenomena in perovskite solar cells. Ways to enhance the performances can be found if the physics behind the functioning of these devices is well understood and if the fabrication technologies are well mastered.

A broad range of complementary experimental techniques – all available within the consortium - will be used to prepare and characterize these structures. Regarding the preparation, the goal is to use low cost printing like methods for deposition of the component layers in the final device. Other methods (e.g. sputtering, vapour deposition or laser ablation) will be used to prepare samples for investigating the physical properties in relation with the structural, electrical and optical quality. The feedback will be used to improve the deposition methods and the structure architecture. Also, the experimental results will be used as inputs in theoretical models allowing predictions for further enhancement of the PCE. The consortium is composed by 6 partners: 3 from Romania (a national research institute as coordinator, an university and a SME as end-user); 2 from Iceland (2 universities), and 1 from Norway (university). The consortium members have all the necessary skills, expertise and infrastructures to successfully fulfill the project objectives within the requested budget.
