Abstract
This work mainly investigates the radiation effects and the damage mechanism on the dye-sensitized solar cells (DSSCs) irradiated by two dose rates of 60Co γ-rays. Experimental results reveal that the performance of DSSC decreases significantly after irradiation, and the degradation rates of the short circuit current and the maximum power in the high dose rate both outweigh those in the low dose rate at the same adsorbed dose. The γ radiation effects on fluorine-doped tin oxide (FTO) and electrolyte were also studied respectively to investigate the degradation rates of DSSC at different dose rates. The results indicate that the degradation rates are closely relative to concentration of γ irradiation-induced defect on FTO.
