Abstract	A new spectrally selective solar absorber coating of TiC-WC/Al₂O₃ tandem layer is designed and prepared on stainless steel (SS) substrate by magnetron sputtering. The coating consists of an absorptance layer (TiC-WC) and an antireflectance layer (Al₂O₃) from substrate to top. The new SS/TiC-WC/Al₂O₃ coating exhibits excellent selective absorbing properties with a high solar absorptance of 0.92 and a low thermal emittance of 0.11. The SS/TiC-WC/Al₂O₃ coating presents a purple color, which is further investigated by chromaticity study. The thermal stability of the coating is evaluated and characterized by SEM, XRD, UV–vis–NIR spectrophotometer, Fourier transform infrared spectroscopy, and Raman spectroscopy. Experimental results indicate that the coating is highly stable in vacuum at 500 °C for 100 h with a good solar selectivity of 0.92/0.11.
