  • Publication number: 20140261390
    Abstract: A solar receiver includes a wavelength selective coating comprising a first diffusion barrier layer, a metallic IR reflective layer, a solar absorptive layer, an anti-reflective layer, and/or a hard coat protective layer. Selective absorber coatings, which are characterized by a high solar absorption coefficient and low thermal emission, can be used to convert captured solar radiation into usable heat. In embodiments, more efficient selective coatings are provided that combine relatively high solar absorbance (e.g., greater than about 0.96) with relatively low thermal emittance (e.g., less than about 0.07 at 700° C.), and that are thermally stable above 600° C., for example, in outdoor conditions. The use of such coatings in a solar field may allow for an increase in the operating efficiencies thereof at operating temperatures of about 600° C. or greater.

  • Patent number: 8318329
    Abstract: The radiation-selective absorber coating (20) has two barrier layers (24a, 24b), an IR-reflecting layer (21) arranged thereon, an absorption layer (22) arranged above the IR-reflecting (21) and an antireflection layer (23) over the absorption layer (22). The absorber tube (13) is a steel tube (1) with the radiation-selective absorber coating (20) applied to the outside thereof. In the process of coating the absorber tube (13) a first oxide barrier layer (24a) is applied to a steel tube by thermal oxidation; a second barrier layer (24b) is then applied by physical gas phase deposition of silicon with supply of oxygen; the IR-reflecting layer (21) is then applied by gas phase deposition of gold, silver, platinum or copper; the absorption layer (22) is then applied by deposition of aluminum and molybdenum; and a final antireflection layer (23) is applied by deposition of silicon with supply of oxygen.

  • Patent number: 7909029
    Abstract: The radiation selective absorber coating of the invention includes two or more barrier layers arranged over each other on a substrate surface, an infrared-range reflective layer arranged on the two or more barrier layers, and at least an absorption layer arranged over the infrared-range reflective layer and a final antireflection layer arranged over the absorption layer. The absorber pipe, especially for a parabolic trough collector, is a steel pipe, on whose outer side the radiation selective absorber coating is applied. In the method of making the absorber pipe a first oxide barrier layer is provided on the outer side of the steel pipe by thermal oxidation, and then a second barrier layer, an infrared-range reflective layer, an absorption layer and a final antireflection layer are applied by gas-phase physical deposition.

  • Patent number: 7637259
    Abstract: The invention relates to a solar collector comprising an absorber tube (13) supported by supports. Radiation-permeable cladding tubes (15) are located between the supports and surround the absorber tube (13). Compensation pieces (17) are provided between the cladding tubes (15) due to the fact that the absorber tube (13) and the cladding tubes (15) have different expansion behaviors. In order to also capture radiation that strikes the connection area (50), at least one mirror collar (20) is provided that reflects the solar radiation into the area of the active absorber tube surface. This mirror collar (20) is capable of reflecting the concentrated solar radiation coming from different directions from the parabolic mirrors even at different solar angles of incidence upon the active absorber surface.

  • Patent number: 7607428
    Abstract: The solar absorber is equipped with an absorber body (10) that absorbs incident solar energy (12) and converts it to heat. The absorber body has a selective absorption layer (17) on a side (36) oriented toward the concentrator (13) and another selective absorption layer (18) on an opposite side (38) oriented away from the concentrator (13). The selective absorption layers (17, 18) have threshold wavelengths below which solar radiation is absorbed and above which a reradiation capacity of the absorber body is suppressed. The threshold wavelength of the selective absorption layer (17) on the side (36) of the absorber body that is oriented toward the concentrator is greater than the other threshold wavelength of the other selective absorption layer(18) on the opposite side (38) of the absorber body oriented away from the concentrator.
