“…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).…”

Solar oven based on sunlight condensation is a promising energy conservation and sustainable solar thermal utility way. However, the temperature of solar oven is greatly affected by the sunshine conditions. In this research, adding phase-change heat storage layer in the solar vacuum tubular collector has been proposed, and the thermal performance has been numerically studied. The influence of the food initial temperature on the temperature distribution of the heat storage layer has been investigated. The results show that adding phase-change heat storage layer (u40 mm/80 mm Â 770 mm) makes the oven inner wall temperature 30 C-80 C higher than that without phase-change heat storage layer when the oven cavity temperature is at a constant of 100 C; and the oven inner wall temperature fluctuation caused by sunshine is obviously reduced from 100 C to 18 C-35 C. It indicates that the food initial temperature has little effect on the temperature field of the heat storage layer with the food initial temperature being 10 C-50 C. The analysis of the heat storage performance shows that the heat storage layer has a certain heat storage capacity in all seasons, and the daily heat storage is up to 2718 kJ.

“…Solar selective absorbing coatings, as the core part among the system, play a significant role in CSP [1]. To achieve as high conversion efficiency as possible, the main requirements for the solar selective absorbing coatings are high absorptance (α) in the solar radiation wavelength range (0.3-2.5μm) and low thermal emittance (ε) in the infrared wavelength region (2.5-25μm) [2].…”

Abstract-A series of AlCrNO based solar selective absorber coatings were deposited by cathodic arc ion plating on three kinds of different infrared reflectors (AlCr, Cu, Cr) and with different deposition currents respectively. The surface morphology, phase structure and surface roughness were characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and roughmeter respectively. The results show that the AlCr-AlCrNO based coating exhibited a high absorptance of 0.91 and an emittance of 0.52 when AlCr was served as infrared reflector. Meanwhile, a higher absorptance (α=0.92) of AlCr-AlCrNO based coating was obtained when varying deposition current from 50 A to 60 A. Moreover, the roughness is one of impacts on the emittance. Increasing the deposition current to 70 A brings about the raising of the roughness, increasing the emittance therefore.
