Hybrid Perovskite Material Processing
First Claim
1. A perovskite material prepared by a process comprising the steps of:
- preparing a thin-film precursor ink, wherein preparing the thin-film precursor ink comprises the steps of;
introducing a lead halide into a first vessel;
introducing a first solvent to the first vessel;
contacting the lead halide with the first solvent to dissolve the lead halide to form a lead halide solution;
introducing a Group 1 metal halide into a second vessel;
introducing a second solvent into the second vessel; and
contacting the Group 1 metal halide with the second solvent to dissolve the Group 1 metal halide to form a Group 1 metal halide solution;
contacting the lead halide solution with the Group 1 metal halide solution to form the thin-film precursor ink;
depositing the thin-film precursor ink onto a substrate;
drying the thin-film precursor ink to form a thin film;
annealing the thin film; and
rinsing the thin film with a salt solution comprising a third solvent and a salt selected from the group consisting of methylammonium halide, formamidinium halide, guanidinium halide, ethene tetramine halide, imidazolium halide, 1,2,2-triaminovinyl ammonium halide, and 5-aminovaleric acid hydrohalide.

Abstract
A method for preparing photoactive perovskite materials. The method comprises the steps of: introducing a lead halide and a first solvent to a first vessel and contacting the lead halide with the first solvent to dissolve the lead halide to form a lead halide solution, introducing a Group 1 metal halide a second solvent into a second vessel and contacting the Group 1 metal halide with the second solvent to dissolve the Group 1 metal halide to form a Group 1 metal halide solution, and contacting the lead halide solution with the Group 1 metal halide solution to form a thin-film precursor ink. The method further comprises depositing the thin-film precursor ink onto a substrate, drying the thin-film precursor ink to form a thin film, annealing the thin film; and rinsing the thin film with a salt solution.
