Nano engineered materials in solar energy systems for clean environment - A review

Abstract

Solar photovoltaic thermal (SPVT) systems are widely used for simultaneous production of electricity and utilization of thermal energy for various applications. Various engineering materials such as nanoparticles, variable phase change materials, individually or in combination are used to absorb the heat from the SPVT systems. The more the absorption of heat, the better the performance of systems. The use of nano engineered materials in SPVT systems enhances the heat transfer rate, optimize the cooling effect and thereby increases the performance of the systems. This paper presents a comprehensive review on the application of engineering materials to improve the performance of the SPVT systems. It also discussed the recent trends, challenging and future scope for enhancing the performance of SPVT systems.
