▎ 摘　　要

NOVELTY - Electrode comprises reduced graphene oxide layer and a metal oxide layer positioned on the reduced graphene oxide layer. USE - The electrode is useful in solar cell, organic light-emitting diode, touch panel and sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing electrode, comprising (a) producing a substrate, (b) forming an graphene oxide layer on the substrate, (c) forming a metal layer on the substrate, and (d) obtaining a reduced graphene oxide layer and a metal oxide layer by oxidation-reduction reaction the metal layer and the graphene oxide layer simultaneously. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the method for producing electrode (Drawing includes non-English language text).
