染料敏化太阳能电池对电极材料的研究进展

Progress in research on counter electrode materials of dye-sensitized solar cells

染料敏化太阳能电池(dye-sensitized solar cell,DSSC)以其低廉的价格、简单的封装工艺、材料的环境友好性、较高的光电转化效率等优点,得到了学术界和工业界的广泛关注.作为染料敏化太阳能电池的重要组成部分,对电极(counter electrode,CE)材料的价格、性能以及制备方法,直接关系到其将来的大规模应用.本文简要介绍了染料敏化太阳能电池的工作原理以及对电极的作用,重点综述了近年来对电极方面具有代表性的研究成果.

Dye-sensitized solar cells （DSSCs） have attracted tremendous scientific and industrial attention because of their low cost, ease of fabrication, environmental friendliness of their raw materials, and relatively high efficiency. The counter electrode is a crucial component of a DSSC; and its price and capability determines the future large-scale manufacture of DSSCs. This review introduces the operational principles of DSSCs and the function of the counter electrode. In particular, the recent progress in new CE materials are summarized.
