| 染料敏化太阳能电池是一种新型的太阳能电池,因具有低成本、易制备、环保等优点而引起全世界的广泛关注。介绍了染料敏化太阳能电池的发展历史、基本结构及工作原理,重点综述了染料敏化剂材料的分类和发展状况。染料敏化剂可分为纯有机染料和配合物染料两大类,纯有机染料敏化剂大致有三苯胺、香豆素、吲哚、花箐和多烯等几类。设计和开发新型纯有机染料敏化剂材料是提高器件光电转化效率较为有效的方法,而多种染料敏化剂协同敏化电池的短路电流密度(J?sc)和开路电压(V?oc)比单一的染料敏化电池更大,因此多种染料共敏化也成为进一步提高染料敏化太阳能电池效率比较可行的途径。最后,展望了有机染料敏化剂的发展前景。 | ||||||||||||

| Dye-sensitized solar cell (DSSC), a new type of solar cell, has aroused worldwide attention which arises from its merits of low cost, ease of fabrication and environmental friendliness, etc. The development history, basic structure and working principle of the DSSC are introduced briefly, and the classification and development of DSSC are stated in detail. Dye sensitizers are divided into two major categories—organic dyes and metal-organic compounds, and organic dyes can roughly be classified into several parts:triphenylamine, coumarin, indole, cyanine and polyene. Designing and exploiting novel organic dye sensitizers is an efficient way to enhance the photoelectric conversion efficiency (PCE, η) of the DSSC. Moreover, cooperative sensitization of several kinds of sensitizers contributes more to the J?sc and V?oc of DSSC than that of single sensitizer, demonstrating that co-sensitization can be an another path to improve photovoltaic performance of DSSC. Finally the paper outlines the development potential of organic dyes. |
