Abstract

Photovoltaic (PV) modules suffer from the exalted temperature in case of outdoor performance. The losses are about more than 25% depending on the arrangement of the materials on the top. If thermoelectric (TE) converter is integrated with the PV modules, then we can form PV-TE hybrid module where TE converter can produce additional electricity due to the difference of the temperature. Nowadays, it is possible to enhance the efficiency by about 23–25% for roof integrated PV-TE devices with the benefit of TE materials performance (Z) of .0042 K-1 at 300 K. The annual energy would be upward by 14.5–15% for two yearly irradiance and temperature profiles which is studied in Dhaka, Khulna respectively. If new materials are manifested, it is possible to enhance the performance by about 50% and annual energy more than 25% may achievable.Keywords: PV module, TE materials, energy, PV-TE devices, TE materials performance, hybrid moduleCite this ArticleMd.
