Process for producing a solar absorber coating, which comprises the steps: coating of a substrate with a titanium precursor solution to produce a titanium dioxide layer by the sol-gel technique and heat treatment of the coated substrate to pyrolyse and crystallize the layer, characterized in that silver ions are added to the titanium precursor solution prior to coating in such an amount that the heat-treated layer has a proportion by mass of silver in the range from 10% to 80% and pyrolysis and crystallization of the layer are carried out with illumination of the layer with visible light. |
