In this study, the effect of gamma ray degradation on silicon solar cells at different doses was investigated and then the aging effect after irradiation was studied. In this study, solar cells were irradiated by gamma rays of the Gamma cell system of the Atomic Energy Organization of Tehran at doses of 0.5, 1, 2, 4, 8, 16 and 32 kGy (dose in water). The dose rate used here was 1.35 Gy/s and the source was cobalt 60 (5,770 Ci). The ISC reduction rate was faster than the VOC reduction rate, and between 4 to 8 kGy, the most changes were observed in the VOC of the cells. After 32 kGy, the average open-circuit voltage and short-circuit current of the cells decreased by 5.38% and 26.16%, respectively. The aging effect over time was investigated in this study and no significant changes were observed in the electrical parameters of the cells.
