Performance Analysis of PV Cell under Uniform and Non-Uniform Illumination

Abstract

The electrical behavior i.e. short circuit current and open circuit voltage is observed. The effects of different temperature and insolation on I-V and P-V curve are studied considering uniform illumination. The study shows that short circuit current and open circuit voltage increases with increase in the insulation. By multiplying these two powers curve is drawn. As the cell’s working temperature increases short circuit current increases and open circuit voltage decreases and accordingly the power is obtained. Then the effect of non-uniform illumination on PV cell with variable shape factor is studied and temperature variation with non-uniformity is observed. By approaching uniform illumination on PV cell mean temperature decreases and accordingly the current output with the variation of shape factor is studied.
