Abstract:

Investment into the EMPOWER allows the growth of a high-quality researchers by synergistically merging photovoltaics and complementary expertise of researchers in MD and RO, boosting their R&I capabilities and bridge the gap between research and technology transfer. The gained knowledge will boost research excellence, visibility and attractiveness of photovoltaic R&D&I in MD and RO. EMPOWER proposes breaking new ideas for the accelerated development and engineering of sustainable antimony chalcogenide alloys with enhanced anisotropy and tunability in their optic and electric properties, and with tunable low-dimensional morphology, for customized power thin film photovoltaics. The project will rationalize implementation of low-cost and efficient disruptive processing technologies for the development, by combining: 1) high throughput low-T synthesis screening; 2) innovative routes for low dimensional morphology selection; and 3) testing and validation of prototyping TF-SC. The ambitious research and innovation goals of EMPOWER lay the foundation for further sustainable development and production of PV in EU. The society as a whole will benefit from excellent job opportunities for specialists, more youths drawn to prestigious technology and engineering oriented higher education, a bridge between R&D&I and the public, and consumers will indirectly benefit from shorter prototype to market development cycles of targeted customized power thin film photovoltaics.

Abstract:

The rapid growth of connected devices and the Internet of Things (IoT) is driving up the demand for sustainable energy solutions that can efficiently convert indoor light into electricity. SUSTA-IN addresses this challenge by developing emerging quasi-one-dimensional (quasi-1D) chalcogenide materials, such as selenium (Se) and antimony sulfide (Sb2S3), for use as absorbers in indoor photovoltaics (IPV). These compounds exhibit strong optical absorption and a suitable wide bandgap (1.8–2.0 eV), as well as being compatible with low-cost, low-temperature deposition processes.

The project's objectives are to optimize the growth and crystallization of quasi-1D chalcogenide thin films, and to engineer transparent oxide selective contacts for efficient charge extraction. Through the integration of physical and chemical methods, SUSTA-IN will establish the technological building blocks for high-performance, stable and environmentally friendly IPV cells capable of powering autonomous IoT devices.
