设计合成了6个带有烷基链的D-π-A型有机光敏染料应用于染料敏化太阳能电池. 发现长链烷基有利于电池开路光电压的提高. 利用脂肪酸共敏化可进一步提高染料分子的敏化效果, 且提高的程度与脂肪酸的链长有重要关系.

Six D-p-A type organic dye molecules bearing alkyl substituents were synthesized and applied as photosensitizers to dye-sensitized solar cells. It was found that the longer alkyl chains might improve the open-circuit voltage. The co-sensitization by fatty acid might enhance the sensitization abilities of the photosensitizers further, and the improvement extents depended on the length of the fatty acids.

Key words: dye-sensitized solar cell, D-p-A type organic dye, alkyl substituent, fatty acid
