ABSTRACT
ABSTRACT: The concept of nanofluid was forward and the innovative PhotoVoltaic-Thermal (PVT) systems design using nanofluid as the heat transfer medium was carried out. The overall efficiencies achieved were over 5% higher than the conventional media, water and air, due to the higher heat capacity of nanofluid. The phase change material was used to store latent heat, which was different from sensible heat. The thermal efficiency of the PVT system was further improved. This article gives a review of the efficiencies of the PVT systems with different media, including air, water, nanofluids, phase change materials, and other hybrid media. The performance of the PVT system was evaluated.
