Abstract
Methods of growing large, free-standing single crystals of (FACs)PbBrperovskites, where 0≤x<1, in solution using tertiary or ternary alkyl ammonium salts, weak organic acids, or a combination thereof are provided. By including the additives in a crystallization solution with perovskite precursors, larger single crystals can be grown by slow evaporation or inverse temperature crystallization than would possible in the absence of the additives under the same growth conditions.
