Optical properties and thermal stability of TiAlN/AlON tandem absorber prepared by reactive DC/RF magnetron sputtering

Chemical bonding states and solar selective characteristics of unbalanced magnetron sputtered TixM1−x−yNy films

“…[3][4][5][6]8,9,20,[30][31][32][33][34] Spectrally selective behaviour of transition metal nitride lms have been previously studied. 10 Studies of magnetron sputtered TiAlN/ TiAlON lms synthesized onto a metal substrate exhibited high absorptance and low emittance were reported by Barshilia et al 5 The absorptance of the lms was substantially enhanced to 0.95 by adding a Si 3 N 4 anti-reective coating on the top of these lms.…”

“…Various types of metal nitrides based selective solar surfaces such as TiN, ZrN, HfN, TiAlN, TiAlON, NbAlN, NbAlON, MoAlN, and WAlN have been investigated by numerous groups. [1][2][3][4][5][6][7][8][9][10][11] Over the past few years, transition metal nitride based thin lms have attracted signicant research interest as selective solar surfaces in solar thermal conversion devices. Generally, the energy conversion performance of a selective solar surface depends on the lm materials, lm design and fabrication technique used.…”

“…A multi-layer lm stack with mixture of metal nitride, metal oxide and metal oxynitride lms e.g., TiAlN/AlON, and TiAl/ TiAlN/TiAlON/TiAlO has been explored for the potential commercial development of selective solar surfaces. 3,12 TiAlN/ TiAlON/Si 3 N 4 selective absorbers have been produced on various substrates such as copper, nickel, stainless steel, glass and nimonic alloys. 13 However, these materials are yet to be commercialized for solar energy conversion applications.…”

Optimization of TiAlN/TiAlON/Si3N4 solar absorber coatings

“…solar absorbers due to their excellent chemical and mechanical stability, high oxidation resistance, and high degree of spectral selectivity (Xie and Hintzen, 2013). TiAlN/TiAlON/Si 3 N 4 ( Barshilia et al, 2006), TiAlN/AlON (Barshilia et al, 2008a), TiAlN/TiAlON/SiO 2 (Rebouta et al, 2012a), Ti 0.5 Al 0.5 N/Ti 0.25 Al 0.75 N/AlN (Du et al, 2011), TiAlON with TiC as buffer layer (Signore et al, 2011), and TiAlSiN/TiAlSiON/SiO 2 (Rebouta et al, 2012b) have been investigated as solar absorbers. The substrate used in these stack absorbers is generally copper because it preserves high thermal and electrical conductivity, and high infrared reflectance.…”
