A photo-electrochemical cell of improved photon conversion efficiency

摘要

A film (23) of a metal oxide semiconductor preferably TiO2, is deposited on the substrate of the anode electrode (20), is sintered by heating the TiO2 particles, where particles sizes between less than 30 nm and sizes more than 100 nm are mixed, and where the average particle size is 30-50 nm, which allows improving the photon conversion efficiency by keeping the dye adsorption area and by improving the light scattering effect.
