The Influence Of Fullerene-Based Interlayers On Ch3nh3pbi3 Perovskite Photodetector

High performance CH3NH3PbI3 perovskite photodetectors are realized by applying thin films of fullerene derivatives as interfacial layers between the metal contact and the perovskite materials. The perovskite photodetector with PC61BM interlayer demonstrates much better performance than that with IC(60)BA interlayer, reaching a responsivity of 57.6 mA/W. The influences of different fullerene derivatives on the photocarriers extraction behaviors at the electrode interfaces are studied.
