Abstract

Cu2S-based counter electrodes screen-printed on different substrates for CdS/CdSe quantum-dot-sensitized solar cells are reported. The photovoltaic conversion efficiency of 3.71% was obtained with Cu2S counter electrode deposited on conductive substrate due to low charge-transfer resistance. By addition of conductive carbon material, a cell with Cu2S/C composite counter electrode screen-printed on insulated glass substrate displayed an efficiency of 3.37%. These results showed the potential application of such Cu2S-based counter electrode for large-scale quantum-dot-sensitized solar cells in the future.
