Research on materials of solar selective absorption coating based on the first principle

Based on the first principle, this paper studies the optical properties of Ni, Mo, CoO, and Cr2O3 according to the Materials Studio software. It is found that the absorptivity of Ni is low, while Ni has low emissivity. Hence, it can be used to reduce emissivity. The absorption rate of CoO is very hi...

The absorption–emission ratio is the highest when the mass ratio is 1:1, and the performance is the best, which is in good agreement with the result of the experiment. And we hope that our method will provide some help for the study of solar selective absorption composite coatings.
