This work explores the effects of 60Co γ-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 light intensity, and a mono-crystalline silicone solar cell with an active area of 10cm×5cm. At room temperature, the forward bias (I-V) and (P-V) characteristics were determined under illumination, before and after irradiation with different 60Co γ-exposure doses; 532mR, 1064mR and 1596mR, respectively. The results demonstrated that γ-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 (Voc), short circuit current (Isc), maximum output power (Pm), fill factor (FF) and efficiency (η) are found to be decreased with gamma exposure doses.
