Dry deposition of perovskite films and solids for optoelectronics

Lead and tin halide perovskites are currently under intense investigation for their potential applications in optoelectronics, due to their favorable and adjustable semiconducting properties. Despite the potential for widespread adoption in the industrial sector, dry deposition of perovskite films and devices remains a specialized area. Here we will examine the latest developments in the vacuum deposition of perovskite films, focusing on methods to manipulate their morphology and structure. Specifically, we will highlight the impact of factors such as composition, deposition rate, and substrate temperature on properties like luminescence quantum yield and recombination lifetime. We will also present a dry synthetic method to prepare powders and functional disks starting from raw chemical precursors. Lastly, we will show the use of these materials in solar cells and photodetectors.
