Abstract
The radiation-selective absorber coating, in particular for an absorber tube of a parabolic trough collector, includes a reflective layer which is reflective in the infrared range, at least one barrier layer arranged below the reflective layer, at least one absorption layer arranged above the reflective layer, an antireflection layer arranged above the absorption layer and at least one adhesion-enhancing layer arranged between the barrier layer and the reflective layer. The adhesion-enhancing layer preferably is a molybdenum layer, but can also be provided by a copper, titanium, titanium oxide, or silicon layer. The adhesion-enhancing layer preferably has a thickness of 5 to 50 nm.
