▎ 摘　　要

NOVELTY - The graphene structure comprises a conductive layer (52) formed of graphene doped with a dopant, and a protective layer that is laminated on the conductive layer and formed of a material having a higher oxidation-reduction potential than water. The protective layer is: a sacrificial layer formed of a material that reacts with water; a non-aqueous solution layer formed of a non-aqueous solution; a sealing layer formed of a material that shields water and covers the conductive layer; and a surplus dopant layer formed of a surplus amount of the dopant, which does not contribute to the doping. USE - The graphene structure is useful as a transparent conductive film in a photoelectric conversion element, a solar cell and an image pickup apparatus (all claimed) and as an electrode of a touch panel. ADVANTAGE - The graphene structure exhibits high conductivity and optical transparency, reduced time degradation of graphene, and increased temporal stability, and enhances photoelectric conversion efficiency and power generating efficiency of the photoelectric conversion element and the solar cell respectively. DETAILED DESCRIPTION - The graphene structure comprises a conductive layer (52) formed of graphene doped with a dopant, and a protective layer that is laminated on the conductive layer and is formed of a material having a higher oxidation-reduction potential than water. The protective layer is: a sacrificial layer formed of a material that reacts with water; a non-aqueous solution layer formed of a non-aqueous solution; a sealing layer formed of a material that shields water and covers the conductive layer; a surplus dopant layer formed of a surplus amount of the dopant, which does not contribute to the doping; and a dried gas layer (53) formed of a dried gas, which does not contain water. An INDEPENDENT CLAIM is included for a method for producing a graphene structure. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a graphene structure.
