Title: Oriented perovskite crystals and methods of making the same

Abstract

An aspect of the present disclosure is a method that includes combining a first organic salt (A1X1), a first metal salt (M1(X2)2), a second organic salt (A2X3), a second metal salt (M2Cl2), and a solvent to form a primary solution, where A1X1 and M1(X2)2 are present in the primary solution at a first ratio between about 0.5 to 1.0 and about 1.5 to 1.0, and A2X3 to M2Cl2 are present in the primary solution at a second ratio between about 2.0 to 1.0 and about 4.0 to 1.0. In some embodiments of the present disclosure, at least one of A1 or A2 may include at least one of an alkyl ammonium, an alkyl diamine, cesium, and/or rubidium.
