Production Process of Photoelectrode for Dye-Sensitized Solar Cell, Photoelectrode for Dye-Sensitized Solar Cell and Dye-Sensitized Solar Cell.

摘要

The invention provides a photoelectrode for dye-sensitized solar cell, by which a dye-sensitized solar cell capable of obtaining a high photoelectric conversion efficiency even when a plastic base is used as a transparent base forming a transparent substrate, and retaining a high level of photoelectric conversion efficiency even when the quantity of incident light is changed can be surely obtained with good reproducibility, a production process thereof, and a dye-sensitized solar cell.;The production process comprises forming a transparent conductive layer on a transparent base to provide a transparent substrate and laminating a photoelectric conversion layer on the transparent conductive layer of the transparent substrate, wherein the photoelectric conversion layer contains at least two kinds of semiconductor particles different in average particle diameter from each other and a sensitizing dye, and the process comprises a step of subjecting a coating film formed on the transparent conductive layer with an aqueous paste containing neither a binder nor an organic solvent and containing said at least two kinds of semiconductor particles different in average particle diameter to a pressing treatment.
