PHOTOVOLTAIC THERMAL TECHNOLOGY WITH COMPOUND PARABOLIC CONCENTRATOR
摘要： The hybrid solar system contains a photovoltaic cell (PV) module and compound parabolic concentrator (CPC). The present study aims to evaluate the potential for the introduction of the PV/T technology into Gujarat, India. The photovoltaic thermal (PV/T) system converts the solar radiation into thermal and electrical energy simultaneously. The solar radiation increases the temperature of PV modules, resulting in a drop in electrical efficiency. Through circulation of water with low temperature, heat can be extracted from the PV modules to improve the electrical efficiency. The extracted thermal energy can be used for heating purpose. The individual electrical efficiency of the PV module and thermal efficiency of CPC have been observed as 13.56% and 53.92% respectively.While the combined efficiency found as 79.18%, which is higher than the individual performance of the PV module and CPC. The combined PV/T system is a new era in solar-based power system.

Evaluation and Design Criteria of Photovoltaic Thermal (PV/T)
摘要： More interesting research in the field of photovoltaic thermal is being conducted widely due to shifting interest in supplying both electrical and thermal needs especially in areas that suffer from small installation space. Photovoltaic thermal (PV/T) offers to produce both electricity and thermal power from solar irradiance within the same area; therefore, saving up space & other costs directed to installation. Moreover, various techniques & types have been studied and implemented to improve PV/T’s performance and combined efficiency. The aim of this paper is to review the fundamentals of this technology, current works in the field and show innovative designs of PV/T to illuminate the way forward for the technology for globe-wide recognition. Nanofluid and nano-PCM based PV/T collector was found to produce the highest efficiency among other types in tropical climate conditions. The performance evaluation criteria for this system was presented and explained. It is recommended to amend the current design by simplifying it for better use in building integrated applications and for residential consumers.
