High Performance Organic Solar Cells Based on a Twisted Bay‐Substituted Tetraphenyl Functionalized Perylenediimide Electron Acceptor

A twisted bay-substituted tetraphenyl functionalized perylenediimide monomer (TP-PDI) is synthesized. A high power conversion efficiency of 4.1% is achieved for organic solar cells incorporated a combination of TP-PDI electron acceptor and PTB7-Th electron donor, indicating that chemical modification of PDI monomers is a useful way of designing high-performance non-fullerene electron acceptors.
