NOVELTY - The utility model belongs to the field of photoelectric detector, perovskite/graphene hybrid specific design based on modified Au MoS2 electrode of photoelectric detector, to down comprising a gate electrode, a gate insulating layer, a vertical graphene nanometer wall/Au modified MoS2 perovskite structure, source electrode and Au modified MoS2 drain electrode. The utility model in the perovskite/vertical graphene nanometer wall hybrid result can well the cavity of photon induced transferred to the graphene from the perovskite, the excitation of electrons in the conduction band without attenuation, cannot return to the valence band to compound with the hole, so as to enhance the lifetime of photo-excited carriers, further increasing the light response. MoS2 can not only as an electrode but also can forms a heterojunction with vertical graphene nanometer wall/perovskite structure, it can better use the light absorption coefficient MoS2 characteristic and high carrier mobility. and MoS2 Au-modified more improves MoS2 ability of the two aspects.
