Abstract: A method for fabricating a layer of material in an organic electronic structure, an organic electronic structure and a perovskite precursor ink for use in fabricating the same. The method includes the steps of: reducing moisture and oxygen content on a surface of a substrate; depositing the material contained in a solution on the surface of the substrate; and facilitating crystallization of the material contained in the solution applied on the surface so as to form the layer of material.

Abstract: A metal oxide ink, a method for manufacturing the metal oxide ink and a method for manufacturing an organic electronic structure using the metal oxide ink. The metal oxide ink includes: a plurality of metal oxide particles suspended in a solvent; and a stabilizer arranged to stabilize the metal oxide particles with a plurality of ligands; wherein the plurality of ligands are arranged to self-dissociate upon a drying process of the solvent.
