▎ 摘　　要

NOVELTY - The method involves mixing raw materials of graphite and turpentine oil through alcohol, ethyl cellulose and absolute ethyl alcohol to prepare graphene slurry. The ethyl cellulose is dissolved in ethyl alcohol. The dissolved cellulose solution is poured into a mortar. A cleaned conductive glass is fixed on a flat working table. Specific amount of prepared slurry is coated on a surface of the glass. A thick film is arranged in an annealing furnace to remove organic component of the thick film. The thick film is naturally cooled to room temperature to obtain a graphene thick-film electrode. USE - Method for preparing a graphene thick-film electrode of a dye-sensitized solar cell. ADVANTAGE - The method enables effectively avoiding film-forming difficulties of the graphene material on the conductive glass substrate, thus simplifying the preparing process of the graphene slurry, and controlling the viscous degree of the slurry, and hence obtaining uniform and controllable thickness of the graphene thick film. The method ensures that the prepared graphene thick film improves high photoelectric conversion performance of a dye-sensitized solar cell. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical illustration of a method for preparing a graphene thick-film electrode of a dye-sensitized solar cell.'(Drawing includes non-English language text)'
