摘要：SnS nanosheets (NSs), SnS nanowires (NWs) and SnS2 nanosheets were synthesized and investigated as counter electrode (CE) catalysts in a I-3(-)/I- based dye- sensitized solar cell (DSC) system for the first time. It is found that the SnS NS based DSCs show comparable power- conversion efficiency (E-ff = 6.56%) to Pt (7.56%), while the E-ff of SnS NW and SnS2 NS based DSCs are 5.00% and 5.14% respectively, indicating the excellent catalytic activity of SnSx for the reduction of triiodide to iodide.
