An All‐Small‐Molecule Organic Solar Cell with High Efficiency Nonfullerene Acceptor

Abstract

An efficient bulk heterojunction all-small-molecule organic solar cell composed of a high-performance small-molecule donor and a self-assembling nonfullerene acceptor is demonstrated. Favorable nanoscale phase separation and enhanced charge carrier generation with transport in this donor–acceptor system assures a maximum power conversion efficiency of 5.4%.
