SnS nanosheets (NSs), SnS nanowires (NWs) and SnS2 nanosheets were synthesized and investigated as counter electrode (CE) catalysts in a I3(-)/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 SnS(x) for the reduction of triiodide to iodide.
首次将 SnS 纳米片（NSs）、SnS 纳米线（NWs）和 SnS2 纳米片合成并作为对电极（CE）催化剂应用于 I3(-)/I(-) 基于的染料敏化太阳能电池（DSC）系统。结果发现，基于 SnS NS 的 DSC 的功率转换效率（E(ff) = 6.56%）可与 Pt（7.56%）相媲美，而基于 SnS NW 和 SnS2 NS 的 DSC 的 E(ff)分别为 5.00%和 5.14%，表明 SnS(x) 对三碘化物还原为碘化物具有优异的催化活性。
