The main goal of this work is to study the effects of resistive switching in organometallic perovskites and their composites with parts of graphene oxide, determination of modes and mechanism of resistive switching. It is found that the resistive switching effect in Ag/[60]PCBM/CH3NH3PbBr3(I3):GO/PEDOT:PSS/ITO/glass films is observed as a sharp change from HRS (high resistance state) to LRS (low resistance state) as both positive and negative biases are applied to Ag and ITO elec-trodes in the darkness and during illumination by a sunlight imitator. The composite films based on organometallic perovskites CH3NH3PbBr3 and CH3NH3PbI3 with graphene oxide (GO) particles with concentration 1â3 wt. % and a layer of [60]PCBM fullerene are promising for the creation of non-volatile RRAM memory cells with electrical and optical information recording. The resistive switching mechanism is assumed to be related to the capture and accumulation of charge carriers in GO particles due to the reduction/oxidation processes.
