High-Temperature Solar Selective Coating

Abstract

Solar energy has maximum potential in comparison with other renewable energy sources. Solar thermal conversion is one of the direct methods for harnessing solar energy using solar selective absorbers. This review article summarizes the recent research progress on the high-temperature solar selective coatings, methodology, and process involved in coating, computer modeling, as well as designs of coatings, optical, compositional, and structural properties of selective coatings. The major bottleneck in developing a solar selective coating is its stability in air at temperature higher than 450°C that possess thermal and structural stability in both individual and combined layers. New possibilities to overcome the abovementioned problems on the performance of solar selective coatings are discussed.
