Abstract:
A photoresponsive electrode used for a wet solar cell, which comprises:a metal film capable of giving a surface plasmon energy to a photoresponsive molecule at occurrence of a surface plasmon resonance;the photoresponsive molecule being fixed on the metal film by chemical reaction using a metal-sulfur bond and being capable of excitation by the surface plasmon energy; anda light-irradiating portion fixed on the metal film and having a dielectric constant different from that of the metal film;wherein the metal film has a thickness capable of satisfying conditions of the surface plasmon resonance with respect to a refractive index of the light-irradiating portion, and when the metal film is irradiated, through the light-irradiating portion, with a p-polarized light at a resonance incident angle, the surface plasmon resonance is induced in an interface between the metal film and the light-irradiating portion.
