Platinum/titanium bilayer deposited on polymer film as efficient counter electrodes for plastic dye-sensitized solar cells
- Graduate School of Engineering, Toin University of Yokohama, Yokohama, Kanagawa 225-8502 (Japan)
A surface-rich platinum/titanium bilayer was deposited on poly(ethylene naphthalate) film by vacuum sputtering as counterelectrode for plastic dye-sensitized solar cells (DSSCs). Compared to the electrodes made of pure Pt layer, this electrode maintained similar electrochemical catalytic effect at relative low Pt usage. Current-voltage characteristics of the plastic DSSC at this stage stand at 0.69 V on V{sub OC}, 9.97 mA/cm{sup 2} on I{sub SC}, 0.69 on fill factor, and 4.31% cell efficiency under AM1.5, 100 mW/cm{sup 2} illumination.
