摘　　要：本文合成了含3种不同取代基的噻吩-三苯胺染料敏化剂(H1,H2和H3),并将其应用于二氧化钛纳米晶染料敏化太阳能电池.系统地研究了3种染料的光物理、电化学和光伏性能.基于H1的染料敏化太阳能电池获得了9.10%的光电转换效率(Voc=0.72V,Jsc=18.03mAcm-2,FF=0.70).Three dye-sensitizers（H1,H2 and H3）containing triphenylamine and thiophene with varied substituent were synthesized and applied in dye-sensitized nanocrystalline TiO2 solar cells.Their photophysical,electrochemical and photovoltaic properties were investigated systematically.The photovoltaic performances of the device based on 3-（5-（4-（diphenylamino）phenyl）-4-methylthiophenyl-2-yl）-2-cyano acrylic acid（H1）showed highest power conversion efficiencies（PCEs）9.10%（Voc=0.72 V,Jsc=18.03 mA cm^-2,FF=0.70）under simulated AM 1.5 G solar irradiation（100 mW cm？2）.
