Using a pentacene/perovskite field effect transistor (FET) test platform, we investigated the interfacial charge transfer associated with optical gating through threshold voltage measurements under illumination. Importantly, bistable electrical conduction in pentacene/perovskite FET devices was achieved as a result of field-induced charge retention at the interface and the origin is discussed to be associated with interfacial charging at the pentacene/perovskite interface. Interfacial contact modification associated with ion migration and other possible effects in the perovskite layer plays a crucial role in forming a functional interface involving organic semiconducting materials.
