Methods for Producing Perovskite-Containing Devices

Kai Zhu (Inventor), Fei Zhang (Inventor), Joseph Berry (Inventor)

Research output: Patent


The present disclosure relates to a method that includes applying a first perovskite precursor solution to a substrate to form a first liquid film of the first perovskite precursor solution on the substrate; from the first liquid film, forming a first intermediate solid perovskite layer on the substrate; repeating at least once, both the applying and the forming, resulting in the creation of at least one additional intermediate solid perovskite layer; and treating a last intermediate solid perovskite layer, resulting from the at least one additional applying and the at least one additional forming, to create a final solid perovskite layer.
