Abstract
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.
Claims9
A process for producing a solar absorber coating, comprising the steps of:
- coating a substrate with a titanium precursor solution to obtain a titanium dioxide layer by the sol-gel technique and heat-treating the coated substrate to pyrolyze and crystallize the layer, characterized in that silver ions are added to the titanium precursor solution before the coating in such an amount that the heat-treated layer has a proportion by mass of silver between 10% and 80% and pyrolysis and crystallization of the layer are effected with illumination of the layer with visible light.
