Abstract Solar thermal energy has often been used as a renewable green energy source. Here we present a design composed of a highly selective solar thermal absorber coating that has been deposited by DC magnetron sputtering. This will consist of four layers: W/AlSiTiNx/SiAlTiOyNx/SiAlOx. The coating that was utilised revealed an excellent average solar thermal absorbance, (α = 95.5%) with very low emittance, (e = 9.6% calculated for 500 °C) together with an excellent thermal stability after annealed at 500 °C, in air for 350 h, and at 630 °C in vacuum for 220 h.

W/AlSiTiNx/SiAlTiOyNx/SiAlOx 多层太阳能热选择性吸收涂层

摘要 太阳能热能经常被用作可再生的绿色能源。在这里，我们提出了一种设计，该设计由通过直流磁控溅射沉积的高选择性太阳能热吸收涂层组成。这将由四层组成：W/AlSiTiNx/SiAlTiOyNx/SiAlOx。所使用的涂层显示出优异的平均太阳能热吸收率 (α = 95.5%) 和非常低的发射率 (e = 9.6% 以 500 °C 计算) 以及在空气中 500 °C 退火后的出色热稳定性350 小时，然后在 630 °C 真空中保持 220 小时。
