摘　　要：介绍了染料敏化二氧化钛纳米晶太阳能电池的结构及工作原理,对影响染料敏化太阳能电池性能的因素,如纳米二氧化钛膜的制备、表面修饰、耦合及掺杂或复合,敏化染料与电极表面的吸附、吸收光谱与太阳光谱的匹配、染料的设计合成,以及电解质的研究进展进行了综述。指出染料和电解质的性能是今后发展中的主要制约因素,纳米多孔膜的制备、染料的光电化学反应机理和染料的设计合成、双敏化、固态空穴传输材料替代液体电解质以及纳晶多孔电极与染料间能量传递及电子转移的微观本质等领域是今后的主要研究方向。The nanocrystalline photoelectrochemical solar cell is a new type of cells because of the low-cost and high-efficiency. The structure and principle of the solar cell based on dye-sensitized TiO2 nanocrystalline thin film were introduced. The effects of TiO2 film, dye-sensitizer and electrolyte on the performance of the solar cell were illustrated. And some key problems that must be solved were put forward, including preparation of nanocrystalline semiconductor electrodes, photoelectrochemical reaction mechanism, design and synthesis and cosensitization of dye-sensitizer, substitution for liquid electrolytes and microscopic essence of electron transfer and energy transmission.
