Enhanced charge separation by interchain hole delocalization in nonfullerene acceptor‐based bulk heterojunction materials

Abstract Bulk heterojunction (BHJ) composites show improved power conversion efficiencies when optimized in terms of morphology using various film processing methods. A reduced carrier recombination loss in an optimized BHJ was characterized previously. However, the driving force that leads to this...
