Abstract

High-dielectric constant side-chain polymers that show reduced non-geminate recombination in heterojunction solar cells are reported. Active layer polymers with high dielectric side-chains show increased performance over alkyl side-chain polymers. The doubling in efficiency is attributed to suppressed recombination. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
