▎ 摘　　要

NOVELTY - A plasmonic core-shell nanostructure comprises a graphene oxide shell formed on a core containing plasmonic metal nanoparticles. USE - Plasmonic core-shell nanostructure is used in photoelectrode for dye-sensitized solar cell (all claimed). ADVANTAGE - The plasmonic core-shell nanostructure has excellent thermal stability and chemical stability. The dye-sensitized solar cell provided with the photoelectrode obtained using the plasmonic core-shell nanostructure has excellent photoelectric conversion efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) photoelectrode; (2) dye-sensitized solar cell; and (3) manufacture of plasmonic core-shell nanostructure.
