Flexible dye-sensitized solar cells (DSSCs) have received widespread attentions in recent years because of their ease of fabrication, low production cost, relatively high chemical stability and flexibility. We report the fabrication of ZnO DSSCs based on the highly flexible, conducting, catalytic and transparent Pt networks counter electrode, and the performance of this solar cell was characterized by SEM, XRD, polarized fluorescence microscope, motor, I-V test station and electrochemical workstation. Compared to Pt nanofiber arrays (NFs), Pt networks not only show a better conductivity, but also exhibit superior transparency and catalytic activity. Furthermore, Pt networks electrode could be constructed on arbitrary flexible substrates. The fabricated flexible ZnO DSSC based on Pt networks counter electrode achieved 1.33% photoelectric conversion efficiency, which is 32% higher than that based on Pt NFs.
