Abstract
The present disclosure relates to a method of preparing a halide perovskite single crystal, including a process of enhancing a solubility of a precursor by using a low-temperature solvent.
Claims8
A method of preparing a halide perovskite single crystal, comprising:
- preparing a perovskite precursor solution by dissolving a perovskite raw material compound in a solvent;
- increasing a solubility of the perovskite precursor solution by controlling a temperature of the perovskite precursor solution;
- and
- growing the halide perovskite single crystal while gradually changing the temperature of the perovskite precursor solution with increased solubility,
- wherein the increasing the solubility of the perovskite precursor solution includes lowering the temperature of the perovskite precursor solution by cooling the perovskite precursor solution.
