Chemically modified photochemical cell
Patent
·
OSTI ID:5460203
A chemically modified photoelectrochemical cell is disclosed including at least one cathode and a plurality of anodes, at least said plurality of anodes being constituted with a semiconductor, each of said plurality of anodes being formed by fixing through covalent bonds molecules of at least one sensitizer dye on the surface of a light-transmissible flat plate of an n-type semiconductor or a light-transmissible flat plate covered with a thin film of an n-type semiconductor, and said plurality of anodes being disposed parallelly to each other and in the form of layers in an electrolyte solution, together with said at least one cathode. Thus, since this photoelectrochemical cell can convert photoenergy of a longer wavelength to electric energy with a high efficiency by making the use of the dye sensitization effect, sufficient practical utility to the photodevices is obtained.
