Abstract
A solar energy absorptive coating for absorbing sunlight energy includes a multilayer stack, including a first absorbing layer with first absorbing layer material for absorbing an absorption radiation of a certain spectrum of the sunlight, a transmission dielectric layer with a transmission dielectric layer material for a transmission of the absorption radiation, and a second absorbing layer with a second absorbing layer material for absorbing the absorption radiation, wherein at least one of the absorbing layer materials has an absorbing layer material refractive index for the absorption radiation, between 1.5 and 4.0, and an absorbing layer material extinction coefficient for the absorption radiation, between 0.8 and 3.0, and the transmission dielectric layer material has a dielectric layer material refractive index for the absorption radiation, between 1.0 and 3.0, and a dielectric layer material extinction coefficient for the absorption radiation, between 0.0 and 0.2.
