“…Some spectrally selective absorber coatings for receiver tubes in open air were reported in last years with excellent photothermal properties and thermal stability in open air atmosphere for T ≈ 300-350°C [12,13]. Other works studied the thermal stability of spectrally selective coatings at higher temperatures both in vacuum and in air conditions [14][15][16][17].…”

“…These coatings can be combined into multilayer structures to optimize their solar performance exhibiting high absorptance (up to 98%) and reduced emittance (<15%). Some high-temperature solar absorber coatings that have already been reported are CrAlN/CrAlON/Al 2 O 3 , CrAlN/CrAlON/Si 3 N 4 , Ti/AlTiN/AlTiON/AlTiO, TiN/AlCrSiO/AlCrSiO, AlMoN­(H)/AlMoN­(L), Mo–Si 3 N 4 , Mo/ZrSiN/ZrSiON/SiO 2 , W/Ag/WN-AlN/AlN/SiO 2 , W/AlSi x N/AlSiO y N x /AlSiO x , W/CrAlSiN x /CrAlSiN x O y /SiAlO x , and W/WAlSiN/SiON/SiO 2 . In addition, a table presenting the solar selectivity of metal nitride/oxynitrides SSC coatings deposited by magnetron sputtering on various substrates can be found in ref .…”

In previous works, Escobar-Galindo et al studied the microstructure, element composition, chemical bonding, and optical properties of Al y Ti 1– y (O x N 1– x ) multilayered coatings, both before and after single-stage (12 h) and thermal cycles in air.…”

“…The WAlSiNbased spectrally-selective solar absorber coating is designed to achieve high solar absorptance and low thermal emissivity at elevated temperatures. Its previously proposed layer stacking was W/WAlSiN/SiON/ SiO 2 and durability tests under various conditions indicated stability in air up to 500 • C and in vacuum up to 700 • C for 200 h [23,24]. We have carried out in situ RBS and SE measurements during heatingcooling cycles between quasi room temperature (25 • C ≤ T ≤ 100 • C) and the three subsequently increased high temperatures of 450 • C, 650 • C and 800 • C. The measurements were performed at the cluster tool facility located at the Ion Beam Center (IBC) of the HZDR [21,22,25].…”
