Title: Organic-inorganic perovskite materials and methods of making the same

Abstract

The present disclosure relates to a method that includes treating a liquid that includes a first precursor at a concentration C1, a second precursor at a concentration C2, a third precursor at a concentration C3, and an additive at a concentration C4, where the treating results in a perovskite, each of C1, C2, and C3 are between 0.001 M and 100 M, inclusively, and at least one of C4/C1 or C4/C2 equals a ratio greater than or equal to zero
