Abstract:
1. A cool dark-colored reflective coating comprising: a base layer having a reflective surface; a dielectric layer formed on said reflective surface; and an absorber layer formed on said dielectric layer formed on said reflective surface of said base layer, said absorber layer comprising a semiconductor material with a band gap of 1.55 to 1.77 eV; wherein said absorber layer comprises amorphous silicon and said dielectric layer comprises silicon nitride, silicon dioxide, nitrides, oxides, or fluorides; wherein an average reflectance of said reflective coating for wavelengths of electromagnetic radiation in the range of 800 to 2500 nm irradiated upon said reflective coating is greater than about 70%, and an average reflectance of said reflective coating for wavelengths of electromagnetic radiation in the range of 400 to 700 nm irradiated upon said reflecting coating is less than said average reflectance of said reflective coating from 800 to 2500 nm.
