Abstract

Although lead halide perovskites with tunable band gaps are widely used for photodetection in the visible spectrum, very few studies have been focused on the use of perovskites in ultraviolet detection. Here, we report that MAPbI_3−xCl_x-based photodetectors (PDs) show a response in the ultraviolet spectrum as well as yield very fast photoresponse speed (< 80 µs/90 µs) and excellent detectivity (10¹² Jones with 365 nm lamp) with very low driving voltage (0.3 V). The results demonstrate the enhancement of photoelectric performance of the PDs in the ultraviolet spectrum is because the doping of Cl in MAPbI₃ increases the bandgap and the crystalline grain size of MAPbI_3−xCl_x film. Moreover, 10%PbCl₂-MAPbI_3−xCl_x-based flexible photodetectors displays remarkable mechanical flexibility.
