摘要:
This study focuses on the synthesis and the performance of non-fullerene acceptors (NFAs) with varying chlorine dispersion in organic solar cells (OSCs). Four chlorine-mediated acceptors, BO3Cl- a , BO3Cl- γ , BO3Cl- β , and BOEH3Cl- β are synthesized with isomeric terminal groups and then integrated with donor PBDB-TF to fabricate OSCs. It finds that increased chlorine dispersion improves device efficiency with enhanced current and BOEH3Cl- β -based devices achieving a power conversion efficiency (PCE) of over 19%, which is one of the high...
