Spectrally selective AlxOy/Pt/AlxOy multilayer absorber coatings were deposited onto
corning 1737 glass, Si (111) and copper substrates using electron beam (e-beam) vacuum
evaporator at room temperature. The employment of ellipsometric measurements and
optical simulation was proposed as an effective method to optimize and deposit multilayer
solar absorber coatings. The optical constants (n and k) measured using spectroscopic
ellipsometry, showed that both AlxOy layers, which used in the coatings, were dielectric in …
