| Trough line focus solar thermal power generation system is the most prospecting research of solar thermal power generation now, the optical properties of solar selective absorption on collector tube surface is the key to improve the efficiency of photo-thermal conversion and reduce the cost.The best way to improve the performance of solar selective absorbing coating includes improving the efficiency of trough line focus solar thermal power generation system and reducing the cost. In addition, improving the operating temperature can increase power generation cycle energy efficiency and reduce the cost of heat storage, thereby reducing the cost of solar power. Therefore, the high temperature (≥450℃) solar selective absorbing coating turns the hotspot research in recent years.In this paper, according to the principle of solar selective absorption coating, we discussed coating structure,material,manufacturing process and the others, With a new cermet coating technology, The experiment results, it has a good optical characteristics and physical properties, At the same time, I made the current development constraints and future development prospects.
