Abstract

The new diketopyrrolopyrrole-based copolymer, referred to as PDPPBDTE, bearing linear alkyl ester groups, was synthesized with the objective of improving the miscibility between the donor polymer and [6,6]-phenyl C₇₁ butyric acid methyl ester (PC₇₁BM). PDPPBDTA bearing ethylhexyl side-chains was also synthesized as a control polymer. The PDPPBDTE:PC₇₁BM blend film showed a relatively small crystalline domain size compared to the PDPPBDTA:PC₇₁BM blend film. A polymer solar cell fabricated with PDPPBDTE and PC₇₁BM exhibited twofold higher power conversion efficiency than that employing PDPPBDTA. [Figure not available: see fulltext.]
