NOVELTY - A nitrogen-doped graphene electrode comprises a substrate and cured uniform layer of nitrogen-doped graphene thin film provided on surface of substrate. USE - Nitrogen-doped graphene electrode for dye-sensitized solar cell. ADVANTAGE - The nitrogen-doped graphene electrode is manufactured with high conductivity, favorable stability, high strength and excellent photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of nitrogen-doped graphene electrode, which involves preparing nitrogen-doped graphene by hydrothermal method, dispersing nitrogen-doped graphene in solvent to form uniform and stable dispersion by ultrasound and stirring, preheating substrate at 45-90 degrees C, coating on surface of substrate, and drying at 50-300 degrees C. The coating method is spin coating, drop coating, spray coating or printing method.
