Abstract
A new solar selective coating was designed in our paper. Ti0.5Al0.5N and Ti0.25Al0.75N coatings were chosen as absorber layers, and AlN coating was chosen as anti-reflection layer. The optical constants of these coatings were studied by spectroscopic ellipsometric. The Ti0.5Al0.5N coating exhibits metallic character. But, the Ti0.25Al0.75N coating exhibits semiconducting property. The AlN coating is expected as a dielectric layer. The solar selective coating was optimized by using a computer program named TFCalc and verified by experimental results. The absorptance and emittance of the optimized solar selective coating were 0.945 and 0.04 (82 °C), respectively.
