Title: Solution growth of single-crystal perovskite structures

Patent ·
OSTI ID:1483380

A method for growing single-crystal perovskite structures comprises immersing a film of a metal precursor compound on a surface of a substrate, the metal precursor compound comprising a metal ion B, in a solution comprising a cation precursor compound, the cation precursor compound comprising a cation ion A and an anion X, at a concentration of the cation precursor compound, a growth time, and a growth temperature sufficient to dissolve the film to release the metal ion B to form a complex with the anion X and sufficient to induce recrystallization of the complex with the cation ion A to form a plurality of single-crystal perovskite structures composed of A, B and X. The single-crystal perovskite structures, devices incorporating the same, and methods of using the devices are also provided.
