Abstract
Methods of growing organometallic halide structures such as AMX3 single crystal organometallic halide perovskites, using the inverse temperature solubility.
Claims18
A method of making an AMX3 structure, comprising:
- dissolving MX2 and AX in a solvent to form dissolved AMX3 in a container, wherein A is an organic cation or Cesium (Cs), M is a divalent cation selected from the group consisting of:
- Pb, Sn, Cu, Ni, Co, Fe, Mn, Pd, Cd, Ge, Cs, or Eu, and X is selected from a halide;
- and
- heating the mixture in the solvent to a temperature to form the AMX3 structure, wherein the temperature corresponds to the inverse temperature solubility for dissolved AMX3.
