We synthesized three soluble perinone isomers as electron transport materials in p-i-n perovskite solar cells. The cis -isomer BBIN-2 possesses higher LUMO level and electron mobility than the trans -isomers. The BBIN-2 devices showed the highest power conversion efficiency of 19.36%, demonstrating the potential of perinone dyes in perovskite solar cells.
