Since solar–thermal collectors are considered to be the most direct way of converting solar
energy into usable forms, 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 embedded in metal nitride/oxynitride 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 in high temperature
(above 400 °C) applications. In this article, we review the present state-of-the-art transition metal
nitride and/or oxynitride based vacuum sputtered nanostructured thin film coatings, with respect
to their optical and solar selective surface applications. We have also summarized the solar
selectivity data from recently published investigations, including discussion on some potential
applications for these materials.
