Abstract:

For the first time, GETICA project proposes to develop and validate an energy independent and combined fully automated greenhouse standalone prototype based on dye sensitized solar cells (DSSCs), as an ongoing and complementary research of the project team. As an important part of Agriculture 4.0 strategy, agrivoltaics can achieve synergistic benefits by growing agricultural plants under raised solar panels. The main limitations of the integration in greenhouse concern the fact that classical PV cells do not transmit sunlight and form a permanent shadow region which has negative effects on production, reducing the crop growth or the amount of biomass. Simple manufacturing process, the low fabrication cost, flexibility in scaling, low material usage and low light level sensitivity, but mainly the variation in color and transparency of the dye sensitized solar cell (DSSC), one of the third generation of PV cells, are essential characteristics that could make these cells the ideal candidate for greenhouse application. To our knowledge (as far as we are aware), no DSSC has been applied in greenhouse for plant growth and energy saving worldwide. We propose the solar radiation manipulation using DSSCs based on UV dye for the protection cells and DNA from damaging UV radiation as well as scavenge free radicals, preventing further cellular damage or IR dye for reducing the temperature of the greenhouse air which leads to an increase in crop production. Moreover, it will be sought reducing production cost of the greenhouse using 3D printing of the modular roofs and DSSCs based on the natural dyes and a low-cost maintenance given by near zero energy input from conventional sources and decreasing the water consumption in irrigation. In this context, GETICA project aims to demonstrate the economic sustainability of this smart greenhouse based on DSSC in the real agriculture.

Thermo-Electric Hybrid Solar System Call name: P 2 - SP 2.1 - Proiect experimental - demonstrativ

Abstract:

The project relates to a solar thermal - electric hybrid, which produces hot water and electricity using thermoelectric modules.

The system is composed of thermoelectric modules, and solar concentrator photovoltaic cells that convert heat to increase efficiency and reduce losses by convection, using a vacuum chamber that allows the positioning unit conversion at any position and allows adjusting the amount wastewater heat transferred by replacing hexagonal mirror solar concentrator photovoltaic.

The thermal solar-electric hybrid system has the following advantages:

- protects the thermoelectric module enclosure from moisture and other natural elements by using the cylindrical shape vacuum device.

- decreases the thermal conductance of the thermoelectric modules by removing the air, thus preventing heat transfer between the hot and cold modules .

- decreases the overall thermal conductance of the thermoelectric conversion module by the use of fastening elements of the glass fiber .

- helps to reduce heat loss by convection due to the use of a vacuum environment.

- provides the possibility to adjust the amount of heat transferred to the assembly by replacing the selective conversion reflecting mirror photovoltaic cells.
