Накратко на български

Хибридни устройства, съчетаващи слънчеви клетки с термоелектрически генератори, улавят топлинните загуби, за да произвеждат повече електричество. По-високата ефективност на тези системи помага за намаляване на разходите за възобновяема енергия и ограничаване на емисиите на въглероден диоксид.

Novel hybrid thermoelectric photovoltaic devices: modeling, development, and characterization

This project aimed at the practical realization, the study, and the commercial evaluation of optimized hybrid thermoelectric – photovoltaic (HTEPV) devices for the efficient harvesting of solar energy. It is in fact well known that common photovoltaic (PV) cells have limited efficiencies, since most of the incoming power is lost as heat. Thermoelectric generators (TEGs), which convert heat into electricity, may be used to recover these losses, enhancing the effectiveness of solar cells. More efficient PV systems can lead to a lower cost of solar harvesters, and to a wider availability and diffusion of this kind of renewable energy in the European community. This can in turn help to meet the important goal of lowering the use of fossil fuel, and reduce the emission of CO2 in the atmosphere, which has dramatic effects on climate and air quality. The overall objective of this action was the practical development of at least two kind of HTEPV prototypes, achieving performances higher by more than 25% than the PV cell alone. The project was successfully implemented and the goal was met with perovskites, and amorphous silicon solar cells. The thermoelectric part of the system was developed with commercially available bismuth telluride but with an optimized and novel device geometry. Efficiency gains were found to be higher in the case of perovskite solar cells, and in the case of optical concentration (the use of lens or parabolic mirrors to enhance the solar input power). The economical evaluation showed that for mid-low optical concentration (5 – 10) hybrid systems based on perovskite solar cells can be cost-effective and potentially competitive in the actual photovoltaic market.

Цел на проекта

This project aims at the practical realization, the characterization, and the industrial/commercial evaluation of optimized hybrid thermoelectric-photovoltaic (HTEPV) devices. HTEPV devices can convert the solar energy more efficiently than normal solar cells, since the thermoelectric component recovers part of the unused heat generated within them. In this project the hybrid optimization will be obtained with an innovative approach recently proposed within a theoretical/computational study by the fellow, Dr. Bruno Lorenzi. The principal objective of this action will be the practical hybridization of two kinds of single junction solar cells in HTEPV devices achieving performances higher than the PV cell alone by at least 25%. The project will be organized in three main phases: outgoing phase (first HTEPV development), ingoing phase (second HTEPV development), and a secondment (encapsulation development at a non-academic institution). Dr. Lorenzi will acquire knowledge and know-how especially by training through research in achieving the objectives of the action. This will contribute to make Dr. Lorenzi an independent and expert researcher in the perspective of his future research carrier. The project will also surely contribute to the advance of field of the energy harvesting. Actually it is well known that for renewables, the higher the efficiency the lower is the total-cost/produced-power ratio. Thus the large expected increase of efficiency for the hybrid devices developed in this action will have a major impact on their price per watt. This will open new concrete possibilities for near-future commercialization of this novel generation of solar harvesters, stimulating industrial productions and new markets. This in turn will lead to a wider diffusion and a higher accessibility of a renewable source of energy for the EU citizens.
