Paper Abstract

There are already a large and varied number of existing selective coatings which are used for photothermal energy conversion, but lately coatings based on thin films produced by sputtering have begun to be used in industry. A coating of this type is based on a multilayer stack consisting of both dielectric and absorbing layers. Included in the absorbing layers are layers which have a dispersion of metal particles in a ceramic matrix, and in general the metal concentration in these layers is not uniform but graded. Programs for the calculation of optical parameters of such a multilayer cannot currently be purchased commercially. Therefore it was decided to develop a program which would calculate the reflectance, solar absorbtivity, thermal emissivity, and photothermal efficiency of a selective coating. Throughout the use of this program, it is possible to calculate the highest photothermal efficiency for any temperature, to evaluate the influence of each individual layer on the resultant behaviour of the entire stack, and to calculate the angular dependence of the solar absorbtivity.
