Method of manufacturing perovskite light emitting device by inkjet printing

摘要

A method of assembling a perovskite light emitting layer is provided. The method includes providing a substrate; Providing a bank structure disposed over the substrate and patterned to define at least one subpixel on the substrate; Providing a perovskite ink comprising at least one solvent and at least one perovskite light emitting material mixed with the at least one solvent; Depositing perovskite ink onto at least one subpixel on the substrate using an inkjet printing method; And assembling a perovskite light emitting layer on at least one subpixel by vacuum drying the perovskite ink in the vacuum drying chamber. A perovskite emissive layer assembled using the method provided is also provided. A perovskite light emitting device comprising a perovskite light emitting layer assembled using the provided method is also provided.
