染料敏化太阳能电池(dye-sensitized solar cells, DSSCs)作为制作工艺简易,成本低廉,环境友好的新型太阳能电池,其发展一直备受关注。对电极作为DSSC的核心部件之一,其制备工艺会直接影响到DSSC的发展和应用。以低成本高性能的催化材料代替传统的贵金属Pt对电极是降低DSSC生产成本的有效途径之一。具有类Pt催化性能的过渡金属化合物(TMCs)由于种类繁多,制备方式简单多样,近年来成为DSSC对电极研究中的热点。本文综述了DSSC过渡金属化合物对电极的最新研究进展,总结概括了过渡金属化合物对电极的制备方法以及性能特点,并对其发展方向和应用前景进行了分析。
Dye-sensitized solar cells (DSSCs) have attracted extensive attention in recent years due to their simple fab-rication, low cost and environmental friendliness. The production process for counter electrode (CE) as one of the key components of DSSC, will significantly affect the DSSCs development and application. Therefore, it is important to develop low cost and high performance catalytic materials instead of noble metal Pt to reduce the production cost of DSSC. Transition metal compounds with Pt-like catalytic activity have become a hot research area for CEs of DSSC in recent years, due to their wide variety and simple preparation. This review briefly addresses recent progresses of tran-sition metal compound CEs of DSSC, focusing on their preparation methods and performance. In addition, the devel-opment trends and application prospects of CEs were also discussed.
