摘要：

This study presents a design of multilayer solar selective absorber for high temperature applications. The optical stack is composed of four layers deposited by magnetron sputtering on stainless steel substrates. The first is a back-reflector tungsten layer, which is followed by two absorption layers based on CrAlSiNx/CrAlSiOyNx,, structure for phase interference. The final layer is an antireflection layer of SiAlOx. The design was theoretically modelled with SCOUT software using transmittance and reflectance curves of individual thin layers, which were deposited on glass substrates. The final design shows simultaneously high solar absorbance alpha = 95.2% and low emissivity epsilon = 9.8% (calculated for 400 degrees C) together with high thermal stability at 400 degrees C, in air, and 600 degrees C in vacuum for 650 h.
