【摘要】 对电极非铂（Pt）催化剂的构筑和性能优化是提升染料敏化太阳能电池（dye-sensitized solar cells, DSSCs）能量转换效率（power conversion efficiency, PCE）和降低成本的重要策略之一.DSSCs传统对电极多采用氟掺杂氧化锡（fluorine-doped tin oxide, FTO）导电玻璃基底负载的贵金属Pt作催化剂.但Pt丰度低、价格昂贵，易被I^-微量腐蚀而消耗.因此，开发高效、稳定、低成本的对电极非Pt催化剂具有重要科学意义和实用价值.总结了近年来单质金属、合金、碳材料、导电聚合物、过渡金属化合物及复合材料在DSSCs对电极中的应用研究进展，讨论了各类材料在催化还原I^-₃/I^-电对方面的优缺点，并对未来新型对电极催化剂的设计策略与发展方向进行了展望.更多还原

【Abstract】 The construction and performance optimization of platinum-free counter electrode catalysts is one of the effective strategies to increase the power conversion efficiency(PCE) and reduce the cost of dye-sensitized solar cells(DSSCs).The traditional counter electrode for DSSCs generally uses noble metal Pt supported on fluorine-doped tin oxide(FTO) conductive glass substrate as the catalyst material.However, Pt is scarce, expensive, and prone to trace corrosion by I~-.Therefore, developing high-efficiency, stable, and low-cost Pt-free counter electrode catalysts has scientific significance and practical value.This paper summarizes the recent research progress on the application of elemental metals, alloys, carbon materials, conductive polymers, transition metal compounds, and composite materials for counter electrodes in DSSCs.Additionally, we discuss the advantages and disadvantages of various materials the catalytic reduction of triiodide/iodide, and propose the design ideas and research directions for novel counter electrode catalysts in the future.更多还原
