The solar selective absorbing coating can convert solar radiation absorption into heat.In order to make full use of solar energy,high temperature selective absorbing coatings are the key components to improve photo-thermal conversion efficiency.Ultra-high temperature carbide ceramic coatings are promising because of their excellent optical properties and high temperature stability.At present,a variety of carbon-based ceramic solar selective absorbing coatings were prepared by magnetron sputtering,spray,sol-gel and laser coating methods,and many studies have been done to optimize their properties.In this paper,the research progress of solar selective absorbing coatings is reviewed.Firstly,the solar spectral selective requirements and the basic principle of selective absorption in carbide ceramics are introduced.Then,preparation method,performance of the carbide solar selective absorption coatings and their influence factors were summarized.Finally,we prospect the carbide development prospects of ultra-high temperature ceramic selective absorbing coatings.
