中文摘要：

在染料敏化太阳电池中,染料敏化剂分成无机染料与有机染料两大类。无机染料受稀有金属钌的制约而成本较高,开发有机染料是降低染料敏化太阳电池成本的有效手段,成为目前研究的热点。本文从有机染料敏化剂的分子设计入手,简述了染料敏化太阳电池中有机染料敏化剂的基本结构,将有机染料敏化剂分为吲哚啉类染料、香豆素类染料、三苯胺类染料、菁类染料、方酸类染料、二烷基苯胺类染料、咔唑类染料、芴类染料、二萘嵌苯类染料、四氢喹啉类染料、卟啉类染料及酞菁类染料等,详细评述了这些有机染料敏化剂及多种染料协同敏化的最新研究进展,并对有机染料的发展前景进行了展望。

英文摘要：

In dye-sensitized solar cell（DSC）,dye sensitizer is the key for the light harvesting in the visible light region,its performance determines the efficiency of DSC to some extent.Up to now,two kinds of dyes,inorganic dyes and organic dyes,have been widely investigated as sensitizers of DSC.In this paper,the basic molecular structures as well as the molecular design for organic dyes are introduced.Organic dyes are divided into indoline dyes,coumarin dyes,triphenylamine dyes and other organic dyes.The newest research progress of these organic dyes and the co-sensitization of different dyes is reviewed in details.The forecast to the future developments of organic dye sensitizers is also discussed.
