Abstract
Embodiments of the present disclosure provide for single crystal organometallic halide perovskites, methods of making, methods of use, devices incorporating single crystal organometallic halide perovskites, and the like.
Claims14
A method of making a single crystal, comprising:
- providing a first reservoir including a first liquid, wherein the first liquid includes a first precursor and an organic cation precursor dissolved in a first liquid solvent;
- providing a second reservoir including a second liquid, wherein the second liquid is a non-solvent;
- wherein the first reservoir and second reservoir are separated by a boundary so that the first liquid and the second liquid do not contact one another, wherein the first reservoir and the second reservoir are in a closed system;
- allowing for vapor diffusion of the second liquid into the first liquid so that the solubility of the first precursor and organic cation precursor gradually decreases;
- and
- precipitating out an organometallic halide perovskite single crystal in the first reservoir.
