Abstract

This work aimed to investigate the effect of commercial UV filter films (PS65, SEC04) on the performance and long-term outdoor stability of dye-sensitised solar cells (DSCs). The application of UV filter films to the DSCs lead to a slight decrease in cell performance. However, the cell performance remained constant after 2,000 h of outdoor exposure. Electrochemical impedance analysis showed a small transfer resistance in the TiO2 photo-anode, which corresponded to the low recombination process of the electrons in TiO2. The low electron recombination process supports the stable performance of the DSCs with the SEC04 film under outdoor conditions.
