Abstract

The present embodiment provides a transparent electrode, a transparent electrode production process and a photoelectric conversion device. The transparent electrode comprises a patterned electrode layer formed on a transparent substrate. The electrode layer has an electroconductive film containing metal nanowires and also has a film of N-graphene. In the graphene carbon skeleton of the N-graphene, carbon atoms are partly substituted with nitrogen atoms. The transparent electrode can be produced by: forming an electroconductive layer by coating with a dispersion containing metal nanowires; then forming an N-graphene film thereon; and subsequently patterning them.
