NOVELTY - Preparing surface modified graphene transparent electrode involves coating nitrogen-doped graphene on a three-dimensional substrate comprising a concavo-convex portion and forming a conductive material on the nitrogen-doped graphene-coated three-dimensional substrate. The three-dimensional substrate including the concave-convex portion is gallium nitride, zinc oxide, indium gallium nitride, alumina or combinations. The recessed portion of the uneven portion is coated with the nitrogen-doped graphene, and the conductive material is formed in the concave portion of the uneven portion. USE - Method for preparing surface modified graphene transparent electrode. DETAILED DESCRIPTION - Preparing surface modified graphene transparent electrode involves coating nitrogen-doped graphene on a three-dimensional substrate comprising a concavo-convex portion and forming a conductive material on the nitrogen-doped graphene-coated three-dimensional substrate. The three-dimensional substrate including the concave-convex portion is gallium nitride, zinc oxide, indium gallium nitride, alumina or combinations. The recessed portion of the uneven portion is coated with the nitrogen-doped graphene, and the conductive material is formed in the concave portion of the uneven portion. The formation of the conductive material on the nitrogen-doped graphene-coated three-dimensional substrate may be performed by the hydrophilic property of the surface of the three-dimensional substrate coated with the nitrogen-doped graphene and the hydrophobic property of the conductive material where the conductive material is bonded onto a three-dimensional substrate coated with nitrogen-doped graphene. The surface of the graphene transparent electrode is in the form of a layer.
