Resumen:
In this work, we report on the deposition and characterization of
selective coatings for solar-to-thermal energy conversion systems for
applications of low to medium temperatures. Both sputtering and
electrodeposition were used to deposit the layers of typical multilayer
coatings. The completely electrodeposited selective films consist of an
infrared reflecting nickel interlayer on stainless steel, and a black
nickel solar absorber material. An alumina/molybdenum/alumina (AMA)
multilayer absorber material was deposited by sputtering on stainless
steel and copper with electrodeposited nickel (Cu/Ni). The optical
properties of the films were studied as a function of the thermal
treatment and were compared with similar selective coatings with
sputtered alumina as antireflective coating. The films were thermally
treated and characterized by reflectance spectroscopy, FESEM, DSC, XRD,
profilometry and Raman measurements. Finally, we report on the scale-up
of these films, and the results obtained on individual fin collectors
showed that our selective coatings exhibit a performance close to the
benchmark coating in the market.
