Abstract

To study the effect of iridium complexes on performance of polymer solar cells, we report the ternary bulk heterojunction (BHJ) polymer solar cells (PSCs) by doping an iridium complex material of bis (1-phenylisoquinoline) acetylacetonate iridium(III) [Ir(piq)₂acac] into the conventional active layer of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C71-butyric acid methyl ester (PC₇₁BM). The results show that the power conversion efficiency (PCE) of P3HT:PC₇₁BM based ternary devices is improved from 2.99% to 4.44% by doping 1 wt% Ir(piq)₂acac, which is benefited from the enhanced exciton harvesting by Förster resonance energy transfer (FRET) from Ir(piq)₂acac to P3HT and optimized self-organized morphology within ternary blends.
