摘要
染料敏化太阳能电池(Dye-Sensitized Solar Cells,DSSC)以其低成本、易加工、高转化等特点受到广泛关注,半导体光阳极是DSSC的重要组成部分,其组成和微观结构直接影响电池性能,中空微/纳结构能够提供高表面积、增加染料负载量、促进光捕获,增强电子传输,因而成为近年来光阳极材料领域的一个热点内容。本文综述了中空微/纳结构光阳极材料的研究进展,主要包括空心球、空心盒、核-壳结构、多级空心、多壳层结构等,并着重分析了各个结构特征与光电转换效率的关系和增益机制,探讨了中空微/纳结构光阳极面临的挑战及发展趋势。
The dye-sensitized solar cell（DSSC） has attracted a great attention in the solar energy conversion fields owing to its advantages including low cost,simple fabrication process,and relatively high efficiency.The component and microstructure of semiconductor photoanode as an important part of DSSC have direct roles on the photoelectrochemical performance of solar cell. Hollow micro/nano-structure can provide large surface area and high loading capacity of dyes,improve the light harvesting and promote the charge transport in photovoltaic devices. Therefore,the photoanode materials with hollow micro/nano-structures became a hot topic in recent years. This review addresses the progress of hollow micro/nano-structured photoanode materials,including hollow microsphere,hollow box,core-shell structure,hierarchical hollow microspheres,multi-shelled structure besides the pure or hybrid components. The relationships between each structure and power conversion efficiency（PCE） are analyzed especially. The facing challenge and prospect of hollow micro/nano-structured photoanode in the future are also discussed.
