“…Bismuth telluride thermoelectric modules and a water heat exchanger were used [15]. This work confirmed the results of earlier simulations [11], [5] and suggested that further hybrid designs should attempt to use smaller length thermoelement modules to capitalise on the small temperature differences in CPV-TE devices.…”

“…In order to provide better information regarding PV‐TEG performance validation and correlation of experimental and theoretical data, Kossyvakis et al conducted experimental and theoretical investigations of a PV‐TEG system with the use of organic solar cell while considering different TEG geometry to study the effect on the performance of the system. The authors concluded after correlating experimental and theoretical data that the use of shorter thermoelement leg length will significantly reduce the amount of heat dissipated by the PV cell thereby enhancing the total efficiency of the PV‐TEG system when operated outdoor.…”

Summary Utilization of a broad range of solar spectrum has the potential for high power output from solar cells. However, solar photovoltaics (PVs) can convert only part of the solar electromagnetic spectrum into electricity efficiently. The remaining of the solar radiation is often dissipated in the form of heat, which causes performance reduction and reduces the life expectancy of the solar PV cell. Thermoelectric generators (TEGs) are devices that operate like a heat engine by converting thermal energy into electricity through thermoelectric effect. Integrating a TEG into a PV converter will enhance its efficiency and reduce the amount of heat dissipated. Different studies have been carried out and are still taking place to increase the total efficiency of a coupled photovoltaic thermoelectric generator (PV‐TEG) system. This review discusses the concept of PV converters and thermoelectric devices and presents the various models and numerical and experimental investigations on performance enhancement of integrated PV‐TEGs. The influence of key parameters on the performance of PV‐TEG were also discussed. The review is expected to serve as a reference to recent work on research and development of integrated PV‐TEG systems.

“…Their results indicate the overall conversion efficiency and power output can be achieved through geometry optimization of the TEG. Results of a theoretical and experimental study [19] shows a TEG with shorter thermoelements is able to provide lower operating temperature for PV module that enhance overall performance of the hybrid module. This optimization is strongly linked to financial feasibility of the hybrid module.…”

a b s t r a c tIn general, modeling of photovoltaic-thermoelectric (PV/TEG) hybrid panels have been mostly simplified and disconnected from the actual ambient conditions and thermal losses from the panel. In this study, a thermally coupled model of PV/TEG panel is established to precisely predict performance of the hybrid system under different weather conditions. The model takes into account solar irradiation, wind speed and ambient temperature as well as convective and radiated heat losses from the front and rear surfaces of the panel. The model is developed for three sample cities in Europe with different weather conditions. The results show that radiated heat loss from the front surface and the convective heat loss due to the wind speed are the most critical parameters on performance of the hybrid panel performance. The results also indicate that, with existing thermoelectric materials, the power generation by the TEG is insignificant compared to electrical output by the PV panel, and the TEG plays only a small role on power generation in the hybrid PV/TEG panel. However, contribution of the TEG in the power generation can be improved via higher ZT thermoelectric materials and geometry optimization of the TEG.
