Abstract:
1. A method for manufacturing a solar selective absorption material, comprising: providing a substrate ; applying thereto at least one layer of at least one IR reflective material; applying to said at least one layer of the at least one IR reflective material at least one layer of at least one solar absorbent material including depositing materials to form said at least one solar absorbent material as a cermet; and applying at least one surface layer of at least one solar antireflective material, to produce a coated substrate having an overall high solar absorbance and a low IR emittance at elevated temperatures, wherein the at least one solar absorbent cermet comprising the deposited materials comprises particles of at least one first metal in the form of a metal silicide, an elemental metal, and mixtures thereof dispersed in the solar absorbent material, wherein the at least one solar absorbent material comprises at least one second metal in the form of a metal oxide, a metal nitride, a metal oxynitride, a metal silicide, a metal boride, a metal carbide, a metal ternary compound, and mixtures thereof, wherein the at least one first metal of the particles comprises at least one of a Group IVA metal, a Group VA metal, a Group VI metal, a noble metal, and mixtures thereof, and wherein the at least one second metal of the solar absorbent material comprises at least one of a Group IVA metal, a Group VA metal, a Group VI metal, a metalloid, a noble metal, and mixtures thereof wherein the high solar absorbance is greater than about
