METHODS FOR PURIFYING PEROVSKITE PRECURSORS AND IMPROVED PEROVSKITES MANUFACTURED THEREFROM

The present disclosure relates to a method that includes preparing a mixture by dissolving at least two halide perovskite precursors in a first liquid, forming a halide perovskite crystal in the mixture by lowering a solubility limit of at least one of the halide perovskite precursors, and separatin...

Zusammenfassung:The present disclosure relates to a method that includes preparing a mixture by dissolving at least two halide perovskite precursors in a first liquid, forming a halide perovskite crystal in the mixture by lowering a solubility limit of at least one of the halide perovskite precursors, and separating the halide perovskite crystal from the mixture, where at least one of the halide perovskite precursors contains an impurity, and the halide perovskite crystal is substantially free of the impurity.
