Abstract

A copper zinc tin sulfide (CZTS) semiconductor can be used as an effective counter-electrode (CE) material in place of platinum metal, yielding low-cost, high-efficiency dye-sensitized solar cells (DSSCs). CZTS nanocrystals were synthesized and then spin-coated on fluorine-doped tin oxide (FTO) glass. After selenization, the power conversion efficiency of the resulting DSSC was comparable that with a Pt CE.
