Abstract: Methods of passivating a surface. The methods may include providing a mixture including a liquid and a derivative of quinacridone, applying the mixture to a first surface of a film that includes a metal halide perovskite, and annealing the film for a time and a temperature effective to convert the derivative of quinacridone to quinacridone. Composite materials and electronic devices also are provided.

Abstract: Bandgap-tunable perovskite compositions are provided having the formula CsPb(AxBy)3, wherein A and B are each a halogen. The mixed halide perovskite composition has a morphology which suppresses phase segregation to stabilize a tuned bandgap of the mixed halide perovskite composition. For example, the perovskite may be in the form of nanocrystals embedded in a non-perovskite matrix, which, for example, may have the formula Cs4Pb(AxBy)6, wherein A and B are each a halogen. Solar cells and light-emitting diodes comprising the mixed perovskite compositions are also provided.
