  • Publication number: 20210383977
    Abstract: The invention provides a method of forming a perovskite film for an optoelectronic device, the method comprising: applying a perovskite precursor solution to at least one part of a hydrophilic region of a substrate, wherein the hydrophilic region is bounded by a hydrophobic boundary; allowing the perovskite precursor solution to spread over the hydrophilic region, wherein the perovskite precursor solution is retained within the hydrophilic region by at least a portion of the hydrophobic boundary; and drying the perovskite precursor solution to form a perovskite film on the hydrophilic region.
