A study was made to characterize parametrically the spectrally selective absorptance profiles of typical interference, bulk absorption, and mixed-type absorbing layers for solar-thermal conversion at temperatures to 500 degrees C. A five parameter empirical Fermi function was used to model the spectral absorptance converted from the measured spectral reflectance. An alternative method using the Fermi model is presented for defining the ir spectral emittance profile, as scaled to the measured hemispherical total emittahce.
开展了一项研究，以参数化表征典型干涉、体吸收和混合型吸收层在高达500摄氏度温度下用于太阳能-热能转换的光谱选择性吸收曲线。使用一个五参数经验费米函数对从测量的光谱反射率转换而来的光谱吸收率进行建模。提出了一种使用费米模型的替代方法来定义红外光谱发射率曲线，并将其按比例换算为测量的半球总发射率。
