(a) Diagram of FAPbBr3 QD/graphene photodetector, and optical and SEM image of the FAPbBr3 QDs.[78] (b) Time-dependent responsivity characteristics of the photodetector. The channel length is 80 μm.[78] (c) 3D schematic view of graphene-PTB7 hybrid photodetector.[79] (d) The responsivities of the SiO2 and ODTS devices as a function of power density at a drain voltage of 3.5 V and without gate voltage.[79]
