Study of the Effects of UV-Exposure on Dye-Sensitized Solar Cells

The aim of this work is to investigate the effects of near-ultraviolet (NUV) irradiation on dye-sensitized solar cells. We monitored the DC parameters, i.e. open-circuit voltage, short-circuit current, and I-V characteristic. The cell impendence was also evaluated by means of electrochemical impendence spectroscopy (EIS). We also monitored the appearance of the cells subjected to NUV irradiation, in order to detect loss of the electrolyte or changes in the cell aspect
