Abstract: Provided are metal halide perovskite light emitting device and method of manufacturing the same. The metal halide perovskite light emitting device uses perovskite film having a multi-dimensional crystal structure derived from a proton transfer reaction as light emitting layer. Due to self-assembled shell of the perovskite film, ion movement is suppressed and surface defects are removed. Thereby, photoluminescence intensity, luminescence efficiency and lifetime are improved. By injecting a fluorine-based material and a basic material into the PEDOT:PSS conductive polymer used as the conventional hole injection layer, the acidity is controlled and the work function of the interface is improved. Furthermore, chemically stable graphene barrier layer protects the electrode vulnerable to acid, so that a high-efficiency light emitting device can be manufactured.
