摘要： Compositions comprise a perovskite and a non-perovskite. Perovskites comprise AxA′yA″(1−x−y)BX3, and non-perovskites may comprise A″, B and X, where A is a first cation, A′ is a second cation, A″ is a third cation, B is a fourth cation, X is an anion. In some instances, A, A′, and A″ are each independently (NH2)2CH+, CH3NH3+, Cs+, Rb+, or (NH2)2(C═NH2)+, with the proviso that A, A′, and A″ are each different. The perovskite may have a first crystal structure in which the anion is corner-sharing, the non-perovskite may have a second crystal structure comprising at least one of an orthorhombic structure, a hexagonal structure, or a perovskite-like structure, and 1−x−y may be greater than about 0.15.
