ABSTRACT

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.
