Protocol for isothermal crystallization of photovoltaic perovskite films based on volatile solvents

The efficient functioning and stability of a perovskite photoactive layer are paramount to the performance of solar cell devices. Here, we present a protocol for the synthesis of a high-performance exemplified methylammonium lead iodide (CH(3)NH(3)PbI(3) or MAPbI(3)) perovskite photoactive layer. We describe steps for preparing the requisite ratios of the precursor powders, synthesizing MAPbI(3) single crystals, and selecting a suitable preparation technique. We then detail a flexible doping strategy for the perovskite photoactive layer. For complete details on the use and execution of this protocol, please refer to Wang and Wu (2020, 2022, 2023).(1)(,)(2)(,)(3)
