Nanometer thick tunable AlHfN coating for solar thermal applications: Transition from absorber to antireflection coating

AlMoN based spectrally selective coating with improved thermal stability for high temperature solar thermal applications

“…In recent years, various cermets and absorber-reflector tandem concept based coatings have been developed for high temperature solar thermal applications (Selvakumar and Barshilia, 2012;Esposito et al, 2009;Antonaia et al, 2010;Lanxner and Elgat (1990); Selvakumar et al, 2015;Rebouta et al, 2015;Jyothi et al, 2015;Liu et al, 2015;Valleti et al, 2014;Gong et al, 2015;Liu et al, 2014). Our group has developed various transition metal nitride/oxide based solar selective coatings for high temperature solar thermal applications (Selvakumar et al, 2015;Jyothi et al, 2015;Selvakumar et al, 2010).…”

“…Our group has developed various transition metal nitride/oxide based solar selective coatings for high temperature solar thermal applications (Selvakumar et al, 2015;Jyothi et al, 2015;Selvakumar et al, 2010). Four layer CrAlO based coating developed by Liu et al using cathodic arc plating technique exhibit very high thermal stability in air (i.e., 800°C for 10 h) .…”

“…The advantages of this proposed coating are its cost effectiveness and the ease of scaling up the process as it utilizes the same material for absorber layer and antireflection coating. Based on this concept, in our previous work, we have developed a novel AlHfN(H)/AlHfN(L) coating with tunable optical properties for high temperature solar thermal applications (Selvakumar et al, 2015). By varying the thicknesses and compositions of AlHfN coatings, the transition from absorber to antireflection behavior was achieved.…”

“…By varying the thicknesses and compositions of AlHfN coatings, the transition from absorber to antireflection behavior was achieved. These coatings were thermally stable in air at 425°C for 2 h and also stable in vacuum at 580°C for 260 h (Selvakumar et al, 2015).…”

A Status Review on Cu2ZnSn(S, Se)4-Based Thin-Film Solar Cells

“…Sputtering. Sputtering is a prevalent method of fabrication that offers uniformity and reproducibility of deposited layer on a large scale [17][18][19][20]. This method is suitable for large scale solar cell production with control over interface engineering, tuning of crystallinity, and the composition of the films [21,22].…”
