Abstract

Metal halide perovskite, a promising semiconductor material, is suitable for new generation optoelectronic application. In comparison to organic -inorganic hybrid perovskites (OIHP), all inorganic CsPbX3 (X = Cl, Br and I) show superior thermal and chemical stability. Although there are many kinds of coating procedures for producing perovskite QDs peorovskite film, most studies of CsPbX3 perovskite thin film fabrication focus on solution processing techniques such as spin coating. Unfortunately, the CsPbBr3 precusor dissolubility is very low compared to OIHP, resulting in a low materials utilization and poor uniformity for the large-scale area. In this work, we report a facile spray coating method to produce CsPbBr3 film on pre-patterned Pt electrode for photodetector (PD) application. The spray-coated perovskite was demonstrated suitable for photodiode application with numbers figure of merit such as: A high responsivity of 60 A/W, high detectivity of 6× 10-13 Jones, the response time (rising and fall time) below 17 ms were obtained at 1 V under 405 nm illumination. From this study, we belive that the spray deposition technique will benefit for futher thin film-based perovskite optoelectronic devices.
