Abstract
Graphene quantum dots (GQDs) synthesized by single phase solution chemistry are embedded in metal halide perovskite (MHP) films because they can act as passivating defects that are present throughout the MHP film, not only at the interface but also throughout the bulk of the film. The perovskite photodetectors composed of indium-doped tin oxide/SnO2/MHP with embedded GQDs/poly triarylamine/Au have the reduced dark current, increased detectivity, and fasted response speed due to lower trap density throughout the bulk MHP layer.
