Abstract

original image

A periodically aligned Pt nanocup array is employed as a counter electrode in dye-sensitized solar cells (DSSCs). The Pt nanocup array enhances the catalytic area, which results in a greater fill factor (FF) and higher short-circuit current (Jsc). A higher density of nanocups is preferable for the performance of DSSCs.
