A new selective surface has been developed on nickel which combines high solar absorptivity (∝s 0.97) with emissivity at 100°C of 0.08. The surface treatment has been applied to thin nickel foil, resulting in a product capable of application to metallic or non metallic (such as concrete, glass, or plastic) substrates. Results show the durability of the surface to be at least equal to existing selective surfaces. Information on adhesives suitable for applying the foil to non-concentating solar collecting systems is given.
