摘　　要：太阳能选择吸收涂层是一种特殊的表面，在0．3～2．5μm太阳光谱范围内具有尽可能高的太阳吸收能力，同时在3～25μm红外波长范围内有尽可能低的热辐射能力。在太阳能热利用中，它能把太阳能富集起来，提高太阳能光热转换效率。近年来，太阳能的中高温利用日益成为人们关注的焦点。系统介绍了选择性吸收涂层的吸收机制、制备工艺，同时对国内外选择吸收涂层的现状做了综述。最近，对金属复合氧化物选择吸收涂层的研究有了新的进展，这类涂层在非真空、高温条件下具有较好的光学性能，且热稳定性好，有望进一步推动中高温太阳能吸收涂层的发展。Solar energy selective absorption coating displayed high absorptivity in solar spectrum in the range of 0.3 -2.5 μm and low emissivity in infrared wavelength of 3 - 25 μm. It could absorb solar energy and improve the efficiency of solar energy photothermal conversion. In recent years, the application of solar energy for medium and high temperature was paid great attention. The absorption mechanisms, prepara-tion techniques were introduced, and the present status of selective absorption coating was summarized. Recently, there was some new progress on absorption coating of metal composite oxides, this type of coating had good optical property and thermal stability in the non-vacuum, high-temperature conditions, and was expected to further promote the development of solar energy absorption coating at high temperature.
