Photoconductive Response to Pulsed UV Light of CsPbCl3 Flexible Thin Films Grown by Magnetron Sputtering

CsPbCl3 perovskite is attracting increasing interest in ultraviolet (UV) detection due to its optical band gap and superior intrinsic optoelectronic properties. In this study, a novel one-step magnetron sputtering technique was applied for fabricating polycrystalline films on flexible plastic substrates with interdigitated contacts. The photoconductive response of 500 nm 1 µm thick pulsed light the 0.1–100 Hz frequency range intensity 10–500 W/m2 tested at room temperature. experimental results demonstrated good performances terms signal stability, fast transient signal, detectivity, dynamic range, dark current noise photodetection UV light.
