作为染料敏化太阳能电池的重要组成部分,对电极的催化性能和价格直接关系到电池的光电转换效率和成本。作为对电极的催化材料,导电聚合物、碳材料和无机化合物等材料虽成本低廉,但其催化性能仍不及金属铂。因此,重点综述了近年来染料敏化太阳能电池纯铂对电极的研究状况,并指出了纯铂对电极中有待解决的问题及今后的发展方向,同时还介绍了染料敏化太阳能电池的工作原理和对电极的作用。
As a crucial component of a dye-sensitized solar cell (DSSC), the counter electrode (CE) plays an important role in the performance and cost of DSSC. Various materials, such as conducting polymer, inorganic compounds and carbon materials, are used as the catalyst of CE, but the catalytic activity of these materials mentioned above are usually lower in comparison with Pt. The progress of Pt CE in recent years are summarized, and the prospects and challenges of Pt CE for their applications are presented. At the same time, the operation principle of DSSC and the function of CE are introduced briefly.
