Claims21
A method for producing a stacked electrode, comprising:
- preparing a multi-layered graphene film directly on an insulating substrate;
- applying a dispersion liquid of metal nanowires directly onto the multi-layered graphene film;
- removing a solvent from the dispersion liquid to prepare a metal wiring on the multi-layered graphene film;
- pressing the metal wiring to prepare a metal wiring on the multi-layered graphene filing and to strengthen the connection between the multi-layered graphene film and the metal nanowires;
- forming a polymer directly on the multi-layered graphene film and the metal wiring to fill asperities of the metal nanowires, wherein the polymer covers the multi-layered graphene film and the metal wiring to obtain a stacked member including the insulating substrate, the multi-layered graphene film, the metal wire, and the polymer;
- and
- cleaving a side of the stacked member where the multi-layered graphene and the insulating substrate are in direct contact and obtaining the stacked electrode including the multi-layered graphene film, the metal wire, and the polymer.
A method for producing a photoelectric conversion device including, as constituents, a stacked electrode, a counter electrode facing the stacked electrode, and a photoelectric conversion layer interposed between the stacked electrode and the counter electrode, wherein
