Abstract
Embodiments relate to methods of forming a halide perovskite crystal. The method involves dispersing a halide perovskite material exhibiting a perovskite crystallographic lattice into a solution. The solution can include amine and a volatile solvent. The method involves forming a metastable intermediate state via amine molecules inserting into the perovskite crystallographic lattice. The method involves transitioning the perovskite material to a photo-sensitive phase via escape of the amine molecules from the perovskite crystallographic lattice. The method involves transitioning the metastable intermediate state to a halide perovskite crystal film.
