Abstract
A method for the production of a photoelectrochemical cell includes forming an anion-doped long-chain alkylthiophene polymer layer on one surface of a semiconductor directly or through the medium of a coating of a noble metal formed in advance on said one surface, interposing a solid electrolyte between a transparent electrode and the anion-dope long-chain alkylthiophene polymer on the semiconductor, and finally connecting a lead wire to the other surface of the semiconductor. A photoelectrochemical cell is produced by the method described above and consists essentially of a layer of an anion-doped long-chain alkylthiophene polymer formed on one surface of a semiconductor directly or through the medium of a coating of a noble metal formed in advance, a transparent electrode, and a solid electrolyte interposed between the polymer layer and the transparent electrode.
