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

Abstract: A method for preparing photoactive perovskite materials. The method comprises the steps of preparing a lead and tin halide precursor ink. Preparing a lead and tin halide precursor ink comprises the steps of introducing a lead halide and a tin halide into a vessel; introducing a first solvent to the vessel; and contacting the lead halide and the halide with the first solvent to dissolve the lead halide and the tin halide to form the lead and tin halide precursor ink; depositing the lead and tin halide precursor ink onto a substrate; drying the lead and tin halide precursor ink to form a thin film; annealing the thin film; and rinsing the thin film with a solvent comprising: a second solvent; a first salt selected from the group consisting of methylammonium halide, formamidinimum halide, guanidinium halide, 1,2,2-triaminovinylammonium halide, and 5-aminovaleric acid hydrohalide; and a second salt selected from the group consisting of methylammonium halide, formamidinimum halide, guanidinium halide, 1,2,2-triaminovinylammonium halide, and 5-aminovaleric acid hydrohalide.

Abstract: A method for preparing photoactive perovskite materials. The method comprises the steps of preparing a bismuth halide precursor ink. Preparing a bismuth halide precursor ink comprises the steps of introducing a bismuth halide into a vessel; introducing a first solvent to the vessel; and contacting the bismuth halide with the first solvent to dissolve the bismuth halide to form the bismuth halide precursor ink; depositing the bismuth halide precursor ink onto a substrate; drying the bismuth halide precursor ink to form a thin film; annealing the thin film; and rinsing the thin film with a solvent comprising: a second solvent; a first salt selected from the group consisting of methylammonium halide, formamidinimum halide, guanidinium halide, 1,2,2-triaminovinylammonium halide, and 5-aminovaleric acid hydrohalide; and a second salt selected from the group consisting of methylammonium halide, formamidinimum halide, guanidinium halide, 1,2,2-triaminovinylammonium halide, and 5-aminovaleric acid hydrohalide.

Abstract: Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer disposed between two electrodes. The active layer may have perovskite material and other material such as mesoporous material, interfacial layers, thin-coat interfacial layers, and combinations thereof. The perovskite material may be photoactive. The perovskite material may be disposed between two or more other materials in the photovoltaic device. Inclusion of these materials in various arrangements within an active layer of a photovoltaic device may improve device performance. Other materials may be included to further improve device performance, such as, for example: additional perovskites, and additional interfacial layers.
