A series of donor–acceptor (D–A) conjugated polymers P1–P4 was synthesized by copolymerization of a novel pentacyclic aromatic lactam acceptor unit, thieno[20,30:5,6]pyrido[3,4-g]thieno[3,2-c]-isoquinoline-5,11(4H,10H)-dione (TPTI), with a donor unit, benzo-[1,2-b:4,5-b0]dithiophene (BDT) or dithieno[3,2-b:20,30-d]silole (DTS). The effect of the donor units and the side chains on TPTI on polymer properties and solar cell performance was investigated. Bulk heterojunction solar cells based on P1 and PC71BM afforded the highest power conversion efficiency (PCE) of 5.30%.
一系列供体-受体(D-A)共轭聚合物 P1-P4 通过将新型五环芳香内酰胺受体单元噻吩[20,30:5,6]吡啶并[3,4-g]噻吩[3,2-c]-异喹啉-5,11(4H,10H)-二酮(TPTI)与供体单元苯并[1,2-b:4,5-b0]二噻吩(BDT)或二噻吩[3,2-b:20,30-d]硅(DTS)共聚合成。研究了供体单元和侧链对 TPTI 对聚合物性质和太阳能电池性能的影响。基于 P1 和 PC71BM 的体异质结太阳能电池获得了 5.30%的最高功率转换效率(PCE)。
