Abstract: The present invention relates to a method of fabricating a nanowire and graphene-sheet hybrid structure, and a transparent electrode employing the same, in which a hybrid structure, in which a graphene sheet is attached on surfaces of nanowires, is fabricated by fabricating a line pattern, in which nanowires are aligned in a longitudinal direction, by using an electro-spinning method, and then additionally employing a dipping method of dipping the line pattern in a graphene sheet dispersed solution, and the fabricated hybrid structure is applied to the transparent electrode. Accordingly, a crosslinking portion is increased by decreasing a distance between nanowires present inside the line pattern to improve a conductive property of a nanowire metal line. Further, the nanowire with a relative uniform density is present within the fabricated line pattern, so that when the line pattern is fabricated on the entire substrate, it is possible to achieve a uniform distribution of nanowires over a large area. Further, the surfaces of the nanowires are covered by the graphene sheet by adopting the dipping process of dipping the nanowire line pattern in a dispersion solution in which the graphene sheet is evenly dispersed, thereby preventing oxidation of the nanowire due to a contact with air during a thermal treatment process.
