High Performance Organic Solar Cells Based on a Twisted Bay‐Substituted Tetraphenyl Functionalized Perylenediimide Electron Acceptor. Issue 11 (7th April 2015) - Cai, Yunhao
Abstract 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.
