摘要： Disclosed is a method for producing a counter electrode based on electrophoretic deposition of graphene. The method includes: adding graphene to a dispersion medium to prepare a graphene dispersion; dipping a transparent electrode in the graphene dispersion and applying a voltage to the transparent electrode for 5 seconds to 5 minutes to deposit the graphene on the transparent electrode; and annealing the graphene-adsorbed transparent electrode at 350 to 600° C. under a nitrogen atmosphere. Also disclosed are a counter electrode produced by the method and a dye-sensitized solar cell including the counter electrode.

摘要： Disclosed is a carbonaceous nanocomposite including: a substrate; a graphene sheet formed on a top surface of the substrate in parallel with the substrate; and a carbonaceous nanomaterial provided on another surface of the graphene sheet, the nanomaterial having an aspect ratio of 2 to 75,000 to make a predetermined angle with the graphene sheet. The carbonaceous nanocomposite according to the present disclosure has excellent adhesivity to the substrate and can be attached to the substrate without undergoing a pasting process. Since a two-directional current flow is generated, the electrical resistance of the graphene and carbon nanotube is considerably reduced. In addition, the graphene allows the carbon nanotube to have a high current density and a high specific surface area, thereby accelerating a redox reaction. The excellent heat-radiating property of the graphene sheet allows fast transfer of heat generated in the carbon nanotube to outside, thereby avoiding degradation of the carbon nanotube. Thus, when employed as an electrode for a battery or a field emission display, a higher current density and an extended lifespan can be achieved when compared with the existing art.
