▎ 摘  要

NOVELTY - The method involves (i) washing the polyethylene terephthalate base material and drying; (ii) preheating the hot stamping roller with grid, (iii) placing the polyethylene terephthalate substrate in the heated hot stamping roller for hot stamping, (iv) depositing graphene the copper foil, (v) coating the polymethyl methacrylate as the supporting material on the substrate, (vi) covering one surface of copper foil deposited graphene on the polyethylene and removing the copper layer to obtain the substrate A; (vii) cleaning the substrate to be treated, soaking in acetone, removing polymethyl methyl acrylate, soaking the processing substrate B in nitric acid solution, allowing to stand, washing to obtain the graphene, transferring the graphene to the grid of the polyethylene terephthalate base material, spin coating polystyrene sulfonate photosensitive layer, annealing, spin coating polystyrene sulfonate photosensitive layer and depositing the top part electrode to obtain the electrode USE - The method is useful for preparing transparent electrode between grid of hot roller impression polyethylene terephthalate substrate is used in organic solar cell and flexible photoelectric device. ADVANTAGE - The electrode has a lower resistivity and a higher transmittance, improves the surface properties of the silver grid by coating graphene, reduces the surface roughness of the embedded silver grid, decreases the sheet resistance of the silver grid/graphene electrode and helps to reduce the resistance of the hybrid electrode.
