Latest Patents
Ahmad Aftab holds a patent for a method of preparing TiO₂ thick film photoanodes. This invention outlines a process that begins with screen printing a film of conductive material on a clean alumina substrate. The conductive layer is then fused through heating. A first layer of TiO₂ particles in an organic carrier is screen-printed over this conductive layer, ensuring that at least 10% of the TiO₂ is in the anatase form. The structure undergoes further heating to burn off the organic carrier and transform part of the TiO₂ to rutile form, enhancing adhesion. A second layer of TiO₂ is applied to address potential pinholes in the first layer, followed by heating in a reducing atmosphere to reduce the electrical resistivity of the films.
