High-performance Ag2BiI5 Pb-free perovskite photodetector
文献摘要：
Recently,lead-free all-inorganic halide perovskites have attracted great interest because they not only have the merits of the halide perovskite family,but also are non-toxic.However,the commercialization of lead-free all-inorganic perovskites is restricted by their relatively low performances,which are usually caused by the fabrication methods and undesirable interfaces between the active layer and carrier transport layers.Herein,we demonstrate a solution-processed route for high-quality Ag2BiI5 lead-free perovskite film by adopting ideal electron transport material SnO2 and a carbon electrode.By optimizing the fabrication process and tailoring the composition of the perovskite active layer,a high-performance photodetector(PD)with an FTO/SnO2/Ag2BiI5/carbon structure PD is first fabricated,which shows good self-powered performance with a detectivity of as high as 5.3 x 1012 Jones and a linear dynamic range of up to 138 dB,which are better than those of the reported Pb-free perovskite PDs and comparable to high-performance Pb-based perovskite PDs.In addition,our unpackaged PDs show good light,thermal,and storage stability in air.Our results provide a special route for the development of lead-free perovskite devices in an environmentally friendly field.
