  • Article with thin film coating having an enhanced emissivity and reduced absorption of radiant energy
    Patent number: 4783373
    Abstract: A coating useful for a solar cell is formed by concurrent deposition of two materials, such as silicon dioxide and magnesium fluoride, on a substrate within a single vacuum chamber. The deposition is monitored to enable control of the ratio of the materials and the thickness of the coating. An alternative embodiment of a coating employs alternating layers of different materials which form pairs or periods, each having a very small optical thickness. By virtue of the coatings, emissivity is enhanced by suppression of the reststrahlen reflectance and solar absorption is reduced by external reflection of the ultraviolet portion of the solar spectrum.
