Abstract
Solar cell efficiency varies with temperature of solar modules. Peak power decreases with increase in module temperature. Hence, it is important to avoid heating of the solar panel to attain maximum possible conversion efficiency. Aim of this paper is to substantiate the relationship between efficiency of solar modules and the effect of thermoelectric in cooling of solar modules in combination (series) with the PCM (phase change material). Thermoelectric effect is attributed to the Peltier effect produced in the thermoelectric cooling (TEC) module, which produces thermal gradient upon current drawn. In this approach, the PV panel is coupled with PCM, at the rear end, which is “latent” energy storage material. TEC modules are connected on the back side of the PCM layer firmly with aluminium heat sink. The setup has also been described in this paper upon which experiment had been run. The conformation of the experimental results with the theoretical concept proves the possible decrease in the operating temperature of the solar cells and increase in the electrical efficiency of the solar module along with the enhancement in the life of the solar panel.
