Fig. 5. (b) I–V curves of the photodetector measured under dark and UV (300), visible (400, 500, 600, and 700 nm), and near-infrared (800, 900 nm) light illumination with the same light intensity of 11.24 mW/cm2. (c) Wavelength-dependent responsivity with a bias of 5.0 V. The light source is the bromine tungsten lamp modulated by optical grating to generate monochromatic light with a minimum step of 5 nm. The inset is the energy band diagrams of the Ag/MAPbI3/Ag structure showing the generation, transfer and collection processes of photogenerated carriers. (d) I–V characteristics of the studied photodetector with different light illumination power (650 nm). (e) On/off ratio, photoresponsivity, and specific detectivity of the photodetectors versus the illuminated light irradiance (650 nm). (f) A comparison of time-dependent photocurrent responses of the detectors made by 1#, 2#, and 3# samples operated at the same applied bias and light illumination power. Fig. 7.
