SPACE ENVIRONMENTAL TESTING OF BLUE RED REFLECTING COVERGLASSES FOR GALLIUM ARSENIDE AND HIGH EFFICIENCY SILICON SOLAR CELLS

摘要

Thermooptical properties of the coverglasses for GaAs and high efficiency Si solar cells are tailored using optical coatings. These coatings are combined with a thin conducting ITO coating that prevents ESDs on solar arrays. The optimal configuration with respect to eliminating ESDs and maximizing end-of-life GaAs array performance is AR/ITO/ RR (RR is a red reflector). For Si arrays, the optimal coating configuration is UVR/RR (UVR is a UV reflector). All ITO coated coverglasses are effective in preventing ESD.
