Abstract

An oxygen-free solar selective absorbing coating of Cu/TiSiN/AlSiN was prepared on a Cu buffered stainless steel substrate by magnetron sputtering. This coating was prepared using a single target for each layer. A spectrophotometer, Fourier transform infrared spectrophotometer, scanning electron microscopy, X-ray diffractometer and atomic force microscopy were used to characterize the optical properties, crystalline structure, morphology and composition of these coatings. The coating of Cu/TiSiN/AlSiN has good optical properties (average absorption of 0.941 and emittance of 0.058) and excellent thermal stability. The performance criterion (PC) is 0.0365, when the solar selective absorbing coating is heated in air at 200 °C for 1200 h.

摘要

通过磁控溅射在铜缓冲不锈钢基底上制备了Cu/TiSiN/AlSiN无氧太阳能选择性吸收涂层。该涂层的每一层均使用单个靶材制备。使用分光光度计、傅里叶变换红外分光光度计、扫描电子显微镜、X射线衍射仪和原子力显微镜对这些涂层的光学性能、晶体结构、形貌和成分进行了表征。Cu/TiSiN/AlSiN涂层具有良好的光学性能（平均吸收率为0.941，发射率为0.058）和优异的热稳定性。当太阳能选择性吸收涂层在空气中200℃加热1200小时时，性能准则（PC）为0.0365。
