Summary: The electric conversion efficiency of a conventional photovoltaic cell in the market is around 13-22%. The remaining part is converted into heat. In this study, a comparative performance analysis was carried out among non-imaging concentrating photovoltaic thermal systems with various truncation levels of the reflector to attain uniform illumination and better electrical and thermal energy conversion performance. The results show that truncation reduces the photovoltaic cell temperature and provides more uniform temperature distribution. Compound Hyperbolic Photovoltaic Thermal system has the highest power generation per unit reflector area for all truncation levels and incidence angles.
