设计合成了以二酮基吡咯(DPP)和5，6-二氟苯并[c][1，2，5]噻二唑(FfBT)为缺电子单元(A)、烷基噻吩基取代苯并二硫(BDTT)(D)为富电子单元(D)的三种新型无规共聚物(Re-P1、Re-P2和Re-P3)。研究了这些三元共聚物在光物理、电化学和光伏性能方面的差异。与无规共聚物Ra-P1相比，规则三元共聚物Re-P2在300~800 nm范围内具有更强的吸收带，更高的空穴迁移率和更合适的表面形态。随着DTffBT用量的增加，规则三元共聚物Re-P3在300-600 nm处表现出比Re-P2更强的吸收带。以这些聚合物为供体材料，以[6，6]-苯基-C71-丁酸甲酯(PC71BM)为受体材料，制备了聚合物太阳电池。其中，基于Re-P3的器件显示出较好的功率转换效率为4.08%，短路电流为8.23mA/cm−2，开路电压为0.76kV，填充系数为65.0%。
Three new random or regular terpolymers (ra-P1, re-P2, and re-P3) based on diketopyrrolopyrrole (DPP) and 5,6-difluorobenzo-[c][1,2,5]thiadiazole (ffBT) as electron-deficient unit (A), alkylthienyl-substituted benzodithiophene (BDTT) as electron-rich units (D) have been designed and synthesized for donor materials in polymer solar cells. The differences on photophysical, electrochemical, and photovoltaic properties of these terpolymers have been investigated. Compared with random terpolymer ra-P1, regular terpolymer re-P2 has stronger absorption band range from 300 to 800 nm, higher hole mobility and more appropriate surface morphology. With increasing the quantity of DTffBT, regular terpolymer re-P3 showed more stronger absorption band in 300–600 nm compared to re-P2. The polymer solar cells have been fabricated by using these terpolymers as donor materials and [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as the acceptor material. Among them, the device based on re-P3 demonstrated preferable power conversion efficiency of 4.08% with a short-circuit current of 8.23 mA cm−2, an open-circuit voltage of 0.76 V and a fill factor of 65.0%.
