From: Metal Electrode-Free Halide Perovskite-Based Flexible Ultraviolet-C Photodetector with Large Area
a Photoresponses of the detector with different incident light intensities from 0.354 to 0.774 mW/cm2 under bending test; b Transient photoresponse and stability of the detector under repeated on/off mode; c I-t curve with 500 on/off cycles; d Current with long-time UV exposure; e Responsivity and specific detectivity as a function of the power light; and f The logarithm of generated current under 254-nm irradiation and on/off ratio as a function of light intensity
