Graphene boosts perovskite single crystal photodetector performance

Due to the wide application of photodetectors in fields including optical communication, environmental monitoring, and image sensing, research for developing highly efficient photodetectors has attracted extensive attention in recent decades. Since 2009, methyl ammonium lead halide (CH3NH3PbX3, X=halogen) perovskites have become a hot topic in material science for light collection in photodetectors.
