Abstract

Metals such as Cu and Cr have good infrared reflection properties, but there are few reports on their effects on the optical properties of solar spectrum absorption layers. Herein, Cu and Cr infrared reflectors were deposited under AlCrNO absorbing layer by multi arc ion plating technology, and the effects of deposition parameters of infrared reflectors on coating properties were studied. The morphology, element composition and phase structure of the coating were analyzed by scanning electron microscope, energy dispersive spectrometer and X - ray diffraction. Results showed that compared with the coating without infrared reflection layer, the coating with Cu infrared reflection layer had the best performance, the absorptivity was increased by 1.7%, and the emissivity was reduced by 31.9%. Besides, the absorptivity and emissivity of coating with Cr infrared reflector were increased by 0.6% and 13%, respectively. Therefore, Cu was better than Cr as infrared reflector.
