Selective coatings for solar energy conversion
Abstract
Optical and thermal properties of electrolytically deposited selective coatings of black nickel, chrome, and copper on galvanized iron have been studied. Correlation between these properties and deposition parameters and structure of the coatings has been established. Stable and adherent black nickel coatings on galvanized iron yield an absorptance of 0.94 and an emittance of 0.09 at 100 C. At an inlet-outlet temperature differences of 61 C, selectively coated collector is 3.7 times more efficient than the nonselectively coated collector.
