Two novel acceptor–acceptor (A–A) type polymeric electron acceptors, PPDI-DTBT and PFPDI-DTBT, which contain perylene diimide (PDI) and fused PDI (FPDI) with electron deficient 4,7-dithienyl-2,1,3-benzothiadiazole (DTBT) units, respectively, are designed and synthesized to investigate their application in all-polymer solar cells (all-PSCs).
