摘　　要：选取吲哚啉染料WBS-1F作为敏化染料,研究了共吸附剂的添加对太阳能电池器件各光伏性能指标的影响.研究发现,向染浴中加入20mmol/L DCA时,短路电流由12.58mA/cm^2大幅提升~30%至16.28mA/cm^2.同时,开路电路相比无添加时的732mV提高了47mV至779mV.因此,共吸附物质的添加不仅能阻止染料的聚集以提高短路电流,同时通过改变染料在TiO_2表面的吸附状态,能够修饰TiO_2表面从而有效降低电池器件内部电子复合速率以提高开路电压.Effects of the co-adsorption material on photovoltaic performance of the WBS-IF sensitized DSSC have been studied in detail. The results show that when 20 mmol/L DCA was added, the short-circuit current increased from 12.58 mA/cm^2 to 16.28 mA/cm^2 and the open-circuit voltage increased from 732 mV to 779 mV. Therefore,the addition of the co-adsorption material can not only enhance the short-circuit current by prohibiting the aggregation of the dye, but also increase the open-circuit voltage by modifying adsorption on the TiO2 surface.
