Patent ID: 8123997

Claim:
A process for preparing a melt-processed perovskite organic-inorganic hybrid material comprising: applying onto a substrate a perovskite organic-inorganic hybrid material; maintaining the substrate and/or the perovskite organic-inorganic hybrid material at a temperature above the melting point of the perovskite organic-inorganic hybrid material but below the decomposition temperature of the perovskite organic-inorganic hybrid material and the substrate for a period of time sufficient to form a uniform melt; and cooling the substrate and/or uniform melt to an ambient temperature under conditions sufficient to form the melt-processed perovskite organic-inorganic hybrid material, wherein the perovskite organic- inorganic hybrid material have a fixed ratio of each organic component and inorganic component and wherein both the organic component and inorganic component manifest forces that enable a self assembly there between into a predictable arrangement.
