A method for forming a nickel oxide layer is disclosed herein. In some embodiments, a method includes depositing a nickel oxide precursor ink on a substrate, wherein the nickel oxide precursor ink comprises a solvent comprising diols, alcohol amines, and water, Ni(NO)·6HO, and at least one metal acetate selected from the group consisting of Ni(CHCO)·4HO and Cu(CHCO)·1HO, annealing the nickel oxide precursor ink at a temperature between 250° to 400° Celsius for between 10 minutes and 6 hours to form a nickel oxide layer, and cooling the nickel oxide layer.

Nickel oxide sol-gel ink

A method for preparing a nickel oxide precursor ink comprising: preparing a solvent comprising diols and alcohol amines; adding nickel nitrate into the solvent to form a nickel nitrate containing solution; adding at least one metal acetate into the nickel nitrate containing solution to form a nickel nitrate and metal acetate containing solution; adding water to the nickel nitrate and metal acetate containing solution to form a nickel oxide precursor mixture; heating the nickel oxide precursor mixture to 60 to 75 Celsius; and cooling the nickel oxide precursor mixture to form the nickel oxide precursor ink.

A composition for use in a preparation of a nickel oxide layer that includes Ni(NO).nHO, wherein n is 0, 4, 6 or 9, at least one metal acetate, and a solvent combination that includes a diol, an alcohol amine, and water.
