Abstract

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 0.69V on VOC, 9.97mA∕cm2 on ISC, 0.69 on fill factor, and 4.31% cell efficiency under AM1.5, 100mW∕cm2 illumination.
