Abstract
The present invention provides a solar absorptive material for a solar selective surface of an absorber of solar radiation. The solar absorptive material comprises a dispersed metallic material and a receiving the top surface boundary through which the solar radiation is received. Further, the solar absorptive material comprises a first region and a second region. The first region being located at a position closer to the receiving boundary than the second region and the first region has an average volume fraction of the dispersed metallic material that is larger than that of the second region.
Claims17
A solar absorptive material for a solar selective surface of an absorber of solar radiation, the solar absorptive material comprising:
- a dispersed metallic material,
- a receiving boundary through which the solar radiation is received,
- a first, a second and a third region, the first region being located at a position closer to the receiving boundary than the second region and having an average volume fraction of the dispersed metallic material that is larger than that of the second region, the third region being positioned at a distance below the receiving boundary that is further than that of the second region and having an average metal volume fraction that is larger than that of the second region.
A solar absorptive material for a solar selective surface of an absorber for solar radiation, the solar absorptive material comprising a silicide material.
A solar absorptive material for a solar selective surface of an absorber of solar radiation, the solar absorptive material comprising:
- at least three layers having a dispersed metallic material, an intermediate one of the at least three layers having an average volume fraction of the dispersed metallic material that is lower than that of the adjacent layers,
- wherein the average metal volume fraction of the intermediate layer is selected so that the diffusion of metallic material from the adjacent layers is substantially inhibited for a temperature range of 300° C. to 500° C.
