An aspect of the present disclosure is a method that includes exchanging at least a portion of a first cation of a perovskite solid with a second cation, where the exchanging is performed by exposing the perovskite solid to a precursor of the second cation, such that the precursor of the second cation oxidizes to form the second cation and the first cation reduces to form a precursor of the first cation.
