Production proceeding of a selectively absorbing titanium nitride layer

In times of controversial nuclear energy, the exploration and further development of systems that are able to use renewable energies become more and more important. Because of its high efficiency and the fast amortization, solar thermal energy is path-breaking. Even though, there is a great variety of solar thermal systems the price of those modules stands in the way of widespread use. One serious cost factor in the production of selective solar absorbance layers is the use of a process related to the physical vapor deposition. This process requires expensive vacuum constructions.

Scientists of Saarland University were able to produce a selective absorbance layer by using atmospheric dip coating. A tandem order was used to generate selectivity: Nano – scaling titanium nitride is able to absorb the incoming solar radiation and transmit it in the infrared band of wavelength. In contrast, the substrate, e.g. build out of aluminum, shows the required reflection at high wavelengths. This technique does not require any vacuum which makes it a cost-effective alternative compared to established production proceedings.
