Effect on Temperature and Efficiency on Photovoltaic Module of PV/T System with Water Based Optical Filter
Abstract: Solar radiation has ultraviolet, visible and infrared radiations, in which infrared and ultra-violet part of the solar radiation are mainly responsible for the heating of solar cell. This decreases the efficiency of the solar cell by –0.3 to –0.5% K-1. When we increase the concentration on the solar cell then the heat becomes more prominent and causes the damage of the solar cell, and also decreases the efficiency of solar …
