摘要
In this paper, we mainly studied the gamma irradiation effects and damage mechanism of dye-sensitized solar cells (DSSCs). The DSSCs were irradiated by gamma irradiation at room temperature. J-V characteristics of cells showed that DSSC parameters such as short circuit current density (J (sc)) and maximum power density (P (max)) decreased significantly after irradiation. The gamma irradiation effects on fluorine-doped tin oxide (FTO), dye sensitizer, and anode were studied respectively to investigate the degradation of DSSC after irradiation. The Ultraviolet-visible spectra of FTO showed that the FTO transmittance decreased. The absorption peaks of dye generated a blue-shift. The X-ray diffraction measurement results indicated that the particle size of nano-crystalline TiO2 was changed after gamma irradiation.
