Abstract
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.
