Abstract

Three A₁-D-A₂-D regular conjugated terpolymers containing diketopyrrolopyrrole, isoindigo, or thienoisoindigo moieties were synthesized. Each terpolymer with the combination of two different acceptors and thiophene as common donor displayed strong absorption from 500 nm to the near-IR region as well as different molecular energy levels. Among three terpolymers, bulk heterojunction polymer solar cell made of the terpolymer containing diketopyrrolopyrrole, isoindigo, and thiophene moieties and phenyl-C71-butyric acid methyl ester showed the highest power conversion efficiency of 6.95% due to its appropriate internal morphology and the high open circuit voltage conferred by the relatively low-lying highest occupied molecular orbital level of the polymer.
