The present invention provides a method for making a highly efficient and inexpensive solar selective coating. Coating consists of various carbon nanotube sheets composite layers, each performing a specific function by incorporating functional materials and components with proper structure. Joule heating of the described solar selective coating allows for efficient functionality even when solar energy is not available.
