摘要: Al–N cermet solar selective coatings with double absorbing layers were deposited on Al substrates via a home-made DC magnetron sputter system. The as-deposited showed high absorptance of 0.942 and normal emittance 0.066 at 80 °C. Thermal accelerated aging tests results that the are durable for least 25 years. Neutral salt spray test coating presents excellent corrosion stability because optical performance (absorptance emittance) coating remained almost unchanged after 200 h test. structural, chemical, evolution heat treatment in air was comprehensively investigated. Our research clearly indicated layer Al–AlN absorber can be used solar-thermal flat plate collectors. Furthermore, we obtained different colored wide range only by tuning thickness (LMVF) AlN anti-reflective (AR) layers, while maintaining (>0.90) low (<0.10). These blue, purple, red, yellowish orange, yellow, easily produced commercial production process, suitable building integration energy saving systems.
