摘　　要：文章选择含长共轭烯烃结构天然染料藏花素、虾青素、番茄红素和β-胡萝卜素用于染料敏化太阳能电池(DSSC)的制备,研究了这些天然染料的分子结构与DSSC性能的关系。研究结果表明,含有极性基团(如-OH等)的天然染料(如虾青素和藏花素)制备的DSSC具有较好的光电转换效率,极性基团是天然染料分子吸附于二氧化钛表面并应用于DSSC制备的必要条件。利用藏花素制备的单个电池器件的开路电压为0.548 V,光电转换效率为0.32%,这在天然染料DSSC器件中,性能是比较高的。A series of natural dyes containing conjugated long alkenes such as crocin, astaxanthin, lycopene, and β-carotene were tried to fabricate dye-sensitized solar Cells （DSSCs）. Relationships between the structures of natural dyes and the performances of the DSSCs were discussed. It was revealed that DSSCs based on natural dyes with polar groups （crocin and astaxanthin） such as -OH performed better, because the natural dyes with polar groups were prone to adsorbed on the surface of titanium dioxide. A decent performance with the solar cell conversion efficiency of 0.32 % and open circuit voltage of 0.548 V was achieved by the DSSCs based on crocin.
