摘要： [Problem] The embodiments provide a process for easily producing an electrode having low resistance, easily subjected to post-process and hardly impairing the device; and also provide, as its application, a production process for a photoelectric conversion device.
[Solution] The process comprises the steps of:
coating a hydrophobic substrate directly with a dispersion of metal nanomaterial, to form a metal nanomaterial layer,
coating the surface of the metal nanomaterial layer with a dispersion of carbon material, to form a carbon material layer and thereby to form an electrode layer comprising a laminate of the metal nanomaterial layer and the carbon material layer,
pressing the carbon material layer onto a hydrophilic substrate so that the surface of the carbon material layer may be directly fixed on the hydrophilic substrate, and
peeling away the hydrophobic substrate so as to transfer the electrode layer onto the hydrophilic substrate.-
