摘　　要：针对有机光伏器件光学吸收效率不高的问题,通过在二元光伏器件PBDB-T/IT-M中添加苝二酰亚胺染料分子(SF-PDI),有效地改善了器件在可见光区(400~550 nm)的光学吸收效率,使得光伏器件在520 nm处的外部量子效率(EQE)从78%增加到85%。进一步调整SF-PDI的含量,光伏器件的短路电流(J_(SC))从16.05 mA·cm^(-2)增加到17.79 mA·cm^(-2),能量转换效率(PCE)从9.98%提高到11.21%。In order to improve the optical absorption efficiency of organic photovoltaic devices,a perylene diimide dye molecule(SF-PDI)was added into the binary photovoltaic devices of PBDB-T/IT-M.It is found that the optical absorption efficiency of the device in the visible region(400~550 nm)was effectively improved,resulting in an external quantum efficiency(EQE)increased from 78% to 85% at 520 nm.With adjusting the content of SF-PDI,the short-circuit current(JSC)of photovoltaic devices increased from 16.05 mA·cm^(-2) to 17.79 mA·cm^(-2),and the energy conversion efficiency(PCE)increased from 9.98% to 11.21%.
