Effet de l’illumination sur les paramètres caractéristiques des cellules solaires au silicium polycristallin

Abstract

This work presents the effect of illumination on the different parameters of a polycrystalline solar cell, under the room temperature, using the single exponential model. The results show that the short circuit current, the , the ideality factor and the maximum power increase linearly. The open circuit voltage and efficiency increase . The fill factor increases slightly for low intensities, and then it decreases with higher intensities of illumination. The current increases exponentially. The series resistance remains invariant and the shunt resistor decreases linearly.
