UV/IR reflecting solar cell cover

摘要

A new solar cell cover comprises a substrate that transmits the spectral region to which the solar cell responds and a multilayer infrared-reflecting coating which incorporates means for suppressing low order reflections. The multilayer coating may also contain ultraviolet or blue coatings and be formed on one or both substrate surfaces. The multilayer coating reflects spectral bands which are adjacent to the short- and long-wavelength limits of the spectral response of the cell. The upper limit wavelength of the short-wavelength reflection band and the lower wavelength limit of the long-wavelength reflection band are independent and may be separately specified.
