太阳光谱选择性吸收表面光学性能计算

OPTICAL PROPERTY CALCULATIONS OF MULTILAYER STACK MODELS FOR SOLAR SELECTIVE ABSORBING SURFACES

发展了多层结构吸收表面的反射率优化设计计算方法。ＳｉＯ２／Ｍｏ－Ｎ－Ｏ／Ｍｏ选择性吸收表面的计算结果与实测结果基本一致，其太阳吸收率和发射率分别为０．９４、０．１９和０．９２、０．２１（６００℃，真空中９０ｍｉｎ退火）。

ptical property calculations for the multilayer stack models have been developed. The optimisation calculations of reflectances of the absorbing surface with multilayer stack structure have been carried out. Good reasonable agreement was obtained between computed and experimentally measured reflectances of the sputtered SiO2/Mo-N -O/Mo selective absorbing surface which has a solar absorptance of about 0.94 and 0.92 (AD and HT). a thermal emittance of approximately 0. 19 and 0.21 for as-deposited and heat treated at 600℃ for 1.5 h in vacuum. respectively.
