Abstract
This work explores the effects of Co-60 gamma-irradiation on the Photovoltaic parameters of a mono-crystalline silicone solar cell. A suitable (light source solar cell) geometry was instrumented. It consists of a halogen lamp of 500W power and 100mW.cm(-2) light intensity, and a mono-crystalline silicone solar cell with an active area of 10cmx 5cm.. At room temperature, the forward bias (I-V) and (P-V) characteristics were determined under illumination, before and after irradiation with different Co-60 gamma-exposure doses; 532mR, 1064mR and 1596mR, respectively. The results demonstrated that gamma-exposure doses have a significant effect on the photovoltaic parameters and it controls the quality and performance of the solar cell. The open circuit voltage (V-oc), short circuit current (I-sc) maximum output power (P-m), fill factor (FF) and efficiency (1) are found to be decreased with gamma exposure doses.
