Graphene containing film, its manufacturing method, graphene containing film laminate and photoelectric conversion element

摘要

Problem to be solved: to provide a photoelectric conversion element using a graphene containing film excellent in electrical characteristics, a manufacturing method thereof, a graphene containing film stack, and a graphene containing film.Photoelectron intensities of graphene containing films of graphene backbone containing graphene containing graphene at the position of 288 EV in the X-ray photoelectron spectroscopy spectra of graphene containing films measured on ITO Films A graphene containing film with a ratio of photoelectron intensities at the energy peak position of the C1s orbit to 5.5 to 20.The graphene containing film can be obtained by heating the oxide graphene containing film in the presence of polyalkylene imine and heating it in the presence of the reducing agent.The graphene containing film can be disposed between the photoelectric conversion layer of the photoelectric conversion element and the electrode.
