Abstract

The high crystallinity and ability to harvest near-infrared photons make diketopyrrolopyrrole (DPP)-based polymers one of the most promising donors for high performing organic solar cells (OSCs). However, DPP-based OSC devices still suffer from the trade-off between energetic loss (Eloss) and maximum external quantum efficiency (EQEmax), which significantly hinders their potential. Thus far, the replacement of fullerenes with small molecule acceptors did not wisdom the performance development of DPP-donor-based solar cells due to severe charge recombination issues. In this work, efficient DPP-based solar cells are reported using low bandgap fused ring electron acceptor, IEICO-4F. PBDTT-DPP:IEICO-4F OSC devices deliver a champion power conversion efficiency of 9.66% with successful interface engineering along with low Eloss of 0.57 eV and a high EQEmax (>70%).
