The invention proposes, as the simplest corresponding component, a thin film applied to a substrate, e.g. made of glass. In this context, the thin layer may consist, e.g., of doped gallium arsenide. Let two electrodes be applied to the gallium arsenide layer at a spacing of, e.g., 1 cm, and let the gallium arsenide layer, in the zone between the electrodes, have a pronounced stoichiometric gradient, i.e. a change in the ratio of Ga to As. Under illumination it is now possible to measure at the electrodes a voltage of a clear few volts. One of the fabrication methods proposed for the thin gallium arsenide film is cathode sputtering (cathodic sputtering). IMAGE
