Study on Experimental Preparation of SS-O Solar Spectrum Selective Absorbing Coating
It is practically significant to develop a kind of selective absorbing coating with excellent performance and usability for flat-plate solar collector,and to work out the related preparation craft.In this article,the Cu-based SS-O solar spectrum flat-plate selective absorption coating system was prepared by the method of direct current reactive sputtering coating films,in which,two layers are SS-O absorbing layer and one is Si-O anti-reflection layer.The reflectance spectra of the absorption coating system was measured by UV3600 spectrophotometer,the reflectance and absorptance of the absorption layer and the anti-reflection layer were calculated,and certain experimental tests were conducted on the prepared absorption coating system in terms of the salt spray resistance performances.The results show that the SS-O selective absorption coating which was prepared by magnetron sputtering technique possesses excellent corrosion resistance,whose absorption rate and the emission ratio have reached the level of the German blue tape series.It can meet the domestic demand for high-level flat-plate market.
