Flexible, UV-responsive perovskite photodetectors with low driving voltage
Source abstract
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 MAPbI3−xClx-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 MAPbI3−xClx film. Moreover, 10%PbCl2-MAPbI3−xClx-based flexible photodetectors displays remarkable mechanical flexibility.
