“…The Al/NbMoN/NbMoON/SiO 2 solar selective absorbing coatings developed for its potential applications in concentrated solar power (CSP) system were deposited onto the stainless steel substrates via magnetron sputtering method [100] (See Figure 7). These coatings show a high value of solar absorptance and higher degree of thermal stability both in air and in vacuum up to 450 °C however, substantial degradation of the optical performance of these coatings was noticed at an annealing temperature of 500°C.…”

Since solar thermal collectors are considered to be the most direct way of converting the solar energy into the usable form, in the last few years growing attention has been paid to the development of transition metal nitride and metal oxynitride based thin film selective surfaces for solar-thermal collectors in order to harvest more solar energy. A solar-thermal energy system, generally, shows very high solar absorption of incident solar radiation from the solar-thermal collectors in the visible range (0.3 to 2.5 µm) and extremely low thermal losses through emission (or high reflection) in the infrared region (≥ 2.5 µm). The efficiency of a solar-thermal energy conversion system can be improved by the use of solar selective surfaces consisting of novel metallic nanoparticles surrounded in metal nitride/oxynitrides systems. In order to enhance the effectiveness of solar thermal devices, solar selective surfaces with high thermal stability are a prerequisite. Over the years, substantial efforts have been made in the field of solar selective surfaces to attain higher solar absorptance and lower thermal emittance at high temperature (above 400°C) applications. In this article, we review the present state-of-the-art transition metal nitride and/or oxynitrides based vacuum sputtered Page 1 of 36 AUTHOR SUBMITTED MANUSCRIPT-JOPT-104532.R1 nanostructured thin film coatings with respect to their optical and solar selective surface applications. We have also summarized the solar selectivity data from recent published literature investigations, including discussion on some potential applications for these materials.

“…[11], using PVD and CVD technology in preparation of substrate [12,13], the solar absorptance of the coating is generally more than 0.9 and emittance is less than 0.2 [14]. In the future, the solar-thermal will be an important expansion direction at 120-250 • C [15]. Restricting the application of coatings to medium and high temperatures is the heat resistance of the coating.…”

The solar selective absorber coating (SSAC) are at the core of the efficient solar-thermal system. In this paper, for the first time, the Chromium-iron oxidation mixture cermet was successfully prepared on the surface of ultra-pure ferritic stainless steel by chemical coloring as SSAC. The coating surface has an optical trap structure, and the chromium-iron oxidation mixture cermet is used as an absorption layer to realize solar-thermal conversion. The solar absorptance (AM1.5) of the coating reached 93.66, and the thermal emittance was less than 13. After thermal shock tests at 25/300 °C done 32 times (accumulated 812.8 h), the Performance Criterion (PC) of the coating was 0.01375 < 0.05, showing outstanding thermal stability.

“…However, such coatings have limited durability at higher temperature due to oxidation or diffusion of the metal component in the dielectric matrix, which limits their applications [18]. On the other hand, transition metal nitrides and oxynitrides based structures are characterized by a good diffusion barrier, high resistance of oxidation, good mechanical, chemical and thermal properties [19][20][21]. Several materials such as TiAlN/AlON, W/WSiAlN x /WSiAlO y N x /SiAlO x , TiAlN/TiAlON/SiO 2 , and WAlN/WAlON/Al 2 O 3 have been reported as selective solar absorbers [22,23].…”

Titanium oxinitride (TiOx Ny ) solar absorber coatings were deposited at different oxygen partial pressures onto Cu, Si and glass substrates using electron beam evaporation technique. XRD diffraction patterns evidenced (111), (200) and (220) orientation of TiNx phase. The preferred orientation of the films changed with oxygen partial pressure. XPS revealed the intensity of both Ti 2P3/2 and Ti 2P1/2 increases as a function of oxygen flow, and also shifted towards higher binding energy, indicating more oxidized state of Ti species than that of TiO2 due to incorporation of nitrogen atoms. Formation of uniformly distributed spherical like particles and an increase in surface roughness of the TiOx Ny films were observed as a function of oxygen partial pressure as depicted from SEM and AFM, respectively. Ellipsometric and resistivity measurements showed a shift from metallic to semiconductor behaviour of the TiOx Ny films as oxygen flow changed. A solar absorptance value of 0.94 in the solar spectrum region and a low thermal emittance value of 0.05 were achieved for the TiOx Ny solar absorber coatings prepared at the oxygen partial pressure of 7.5x10-5 Torr due to both interference and intrinsic absorption. This study confirmed that a single layer of TiOx Ny film can be a good candidate as selective solar absorber.
