Abstract

Photovoltaic cells can produce electrical energy from irradiance; however besides than electrical energy transformation, the remainder energy can also be transformed into thermal energy which increases the temperature of PV cell. The high operating temperature in PV cell will affect the electrical power output and PV cell lifespan. Numbers of researchers had designed different Photovoltaic/Thermal collector for cooling with better electrical and thermal efficiency. This paper presents a review of literature available that cover different configuration and design of water Photovoltaic/Thermal and their performances in terms of electrical efficiency. The review covers detailed previous researchers work of experimental design and the evaluation of the electrical efficiency. It can be concluded that, the performance of PV/T system depends on the factor of different cooling methods of passive and active, type and size of the cell, and climatic factors such as solar radiation and ambient temperature.
