摘　　要：Cu, Cr等金属具有良好的红外反射性能,但鲜见其对太阳能光谱吸收层光学性能影响的报道。采用多弧离子镀技术在AlCrNO吸收层下方分别沉积Cu, Cr红外反射层,并研究红外反射层的沉积参数对涂层性能的影响。采用扫描电子显微镜、能谱仪及X射线衍射仪分析涂层形貌、组成元素及物相结构。结果表明,与没有红外反射层的涂层相比,加入Cu红外反射层的涂层性能最好,吸收率提高了1.7%,发射率降低了31.9%。Cr作为红外反射层的涂层吸收率提高了0.6%,发射率降低了13.0%。Cu作为红外反射层的性能优于Cr。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.
