Abstract
Disclosed herein is a solar converter structure and fabrication process therefor which includes a composite zinc selenide fluorescent wavelength shifter (FWS) prepared with anti-reflective (AR) coatings on both major surfaces thereof. One of these AR coatings is adhesively bonded to an AR coating on the sunlight-receiving surface of a gallium arsenide or an aluminum gallium arsenide photovoltaic (PV) solar cell, and the 'free-standing' FWS composite wavelength shifter protects the solar cell from proton and ultraviolet radiation damage. The ZnSe wavelength shifter has a spectral response below about 0.47 micrometers and the solar cell has a spectral response above about 0.47 micrometers. The wavelength shifter absorbs radiation in the 0.3 to 0.47 micrometer range and re-emits radiation to the solar cell in a band centered about 0.62 micrometers and well within the pn junction response spectra for the solar cell to thereby enhance its power output.
