Halide perovskite for photodetector applications

Halide perovskite has dawned as a novel material for photovoltaic applications owing to its futuristic characteristics. Furthermore, its exceptional characteristics such as simplicity and affordability of fabrication, long diffusion lengths, adjustable spectral absorption range, and high carrier mobility render it one of the market-competitive and most exceptional materials beyond photovoltaics such as photodetectors, lasers, light-emitting diodes (LED), memory devices, etc. Furthermore, the perovskite versatility in device architecture supports in achieving relatively higher performance devices. This chapter explains why halide perovskite materials are becoming more popular for a wide range of applications by describing their distinctive qualities, such as electrical and optical properties. Finally, this chapter also discusses the challenges to be overcome for several applications and the gold standards of perovskite as next-generation optoelectronics devices.
