摘要：

A simple method for theoretical prediction of optimum thickness to maximise the spectral selectivity of the absorber in photothermal conversion of solar energy is presented. The optical properties of the absorber are described in terms of Kubelka-Munk theory. The calculation is applied on black thickness-sensitive spectrally selective paint coatings. The obtained optimum thicknesses are compared with values which have been established by experimental optimisation.
