ABSTRACT:
Disclosed are a photo-semiconductive electrode that has a high light-to-electricity conversion efficiency and excellent stability and can be prepared economically and easily, and a photo-electric cell using the photo-semiconductive electrode. The photo-electric cell comprises a photo-semiconductive electrode having an electroconductive base and a light-to-electricity conversion layer formed thereon, and a counter electrode, such that the photo-semiconductive electrode and the counter electrode contact an electrolyte, wherein the light-to-electricity conversion layer holds an organic pigment. In the photo-electric cell, the photo-semiconductive electrode and the counter electrode are used integrally and disposed so that these electrodes contact the electrolyte. The organic pigment suited for use in the layer is selected from the group consisting of: phthalocyanine pigment such as titanyl phthalocyanine, chlorogallium phthalocyanine and hydroxygallium phthalocyanine; and naphthalocyanine pigments.
