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.
Claims20
A method of passivating a surface, the method comprising:
- providing a mixture comprising a liquid and a derivative of quinacridone, wherein the derivative of quinacridone is at least partially dissolved in the liquid;
- applying the mixture to a first surface of a film, wherein the film comprises a metal halide perovskite;
- and
- annealing the film for a time and a temperature effective to convert the derivative of quinacridone to quinacridone.
1 more element
A composite material comprising:
- a film comprising a metal halide perovskite, the film having a first side and a second side opposite the first side;
- and
- a coating comprising quinacridone, wherein the coating at least partially coats the first side of the film.
