▎ 摘  要

NOVELTY - The transparent electrode (10) comprises a grid structure (14), a graphene film (12) associated with the grid structure, and a substrate (16). The grid structure and the graphene film are adhesively associated with each other. The graphene film: is positioned on a top surface of the grid structure; is a monolayer; comprises 2-9 layers; and comprises pristine graphene, doped graphene and sprayed graphene particles. The grid structure consists of metals, and carbon nanotubes including single-walled carbon nanotubes, multi-walled carbon nanotubes and double-walled carbon nanotubes. USE - The hybrid transparent electrode is useful for optoelectronic applications such as organic photovoltaics, organic light emitting devices, LCD devices, touch screens, smart window panes and head-up displays that are useful in windscreens, goggles, glasses and visors, and useful in flexible solar cells and organic light emitting diodes. ADVANTAGE - The hybrid transparent electrode can be effectively and economically manufactured with high transparency, conductivity, flexibility, strength and robustness, long lifespan and low sheet resistance. DETAILED DESCRIPTION - The transparent electrode (10) comprises a grid structure (14), a graphene film (12) associated with the grid structure, and a substrate (16). The grid structure and the graphene film are adhesively associated with each other. The graphene film: is positioned on a top surface of the grid structure; is a monolayer; comprises 2-9 layers; and comprises pristine graphene, doped graphene and sprayed graphene particles. The grid structure: consists of metals, carbon nanotubes including single-walled carbon nanotubes, multi-walled carbon nanotubes, double-walled carbon nanotubes and/or ultrashort carbon nanotubes, graphite, amorphous carbons, metal particles, metal nanoparticles and/or metal microparticles; and is positioned on a top surface of the substrate. The sprayed graphene particles consists of graphene nanoflakes, graphene nanoribbons, exfoliated graphite, reduced graphene oxide, and/or split carbon nanotubes. The substrate is arranged beneath the grid structure and the graphene film. The electrode has a transparency of more than 70% in a wavelength region of 400-1200 nm. An INDEPENDENT CLAIM is included for a method of making a transparent electrode. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a transparent electrode.
