Abstract: The high temperature receiver tube is the core component of the parabolic trough solar power generation system, and has a direct bearing on the efficiency of the system. By using the sol-gel and dip coating method, anti-reflective coatings are prepared on the surface of the high temperature receiver tube. Thus the thermal efficiency of the high temperature receiver tube is increased. An automatic production line of anti-reflection coating for solar collector tubes is developed to enhance its industrialized production capacity.
