摘要： This invention provides a solar heat-collecting pipe that includes, in the stated order from the inner side on the outer surface of a ferrous material pipe through the interior of which a heat transfer medium is allowed to flow, at least a first diffusion-preventing layer, a second diffusion-preventing layer, an infrared radiation-reflecting layer, a sunlight-to-heat conversion layer and an anti-reflection layer. The first diffusion-preventing layer includes at least one selected from the group consisting of silicon oxide, aluminum oxide and chromium oxide. The second diffusion-preventing layer includes at least one selected from the group consisting of tantalum nitride, tantalum oxynitride, titanium nitride, titanium oxynitride, niobium nitride, and niobium oxynitride.

摘要： A coating for solar tubes has a porous absorbing layer that includes an absorbing black pigment material mixed with a porous binder having an open porosity, and a first protective layer having oxides applied on top of the porous absorbing layer. The first protective layer may penetrate to at least a portion of the open porosity. The first protective layer may include nanoparticles, to improve the filling of the pores. A second protective layer may be applied after the first layer, to improve the filling of the remaining gaps.

摘要： A gas receiver configured to heat a working fluid is disclosed. The receiver comprises an aperture, a light absorber, and a pre-heater interposed between the aperture and light absorber. The pre-heater is transparent to visible light and opaque to infrared. The pre-heater in the preferred embodiment comprises quartz in the form of a plurality of quartz plates or quartz tubes, for example, that are oriented substantially parallel to one another. The quartz plates are separated from one another by a gap to permit air to pass into the receiver cavity, while the quartz tubes are hollow to permit air to pass therethrough. The quartz plates or tubes are configured to transmit visible light from the aperture to the light absorber, and to absorb infrared radiation passing from the light absorber toward the aperture. Since the quartz structures absorb infrared, they serve to capture blackbody radiation emitted from the absorber and use that energy to pre-heat air before it passes into the absorber.

摘要： A method is disclosed for producing a plasmonic-nanostructure spectrally selective solar absorber having high solar absorptance, low thermal emittance, and superior thermal stability. The method includes the steps of providing an alloy structure containing a base metal and a copper alloying impurity, wherein copper has a weight percent concentration in the alloy of at least 0.25%; and applying an alkaline solution to a surface of the alloy structure to selectively dissolve base metal elements at the surface resulting in fabrication of sponge-like copper nanostructures on the surface configured to scatter, trap, and absorb light in solar wavelengths.
