The use of spectrally selective coatings as filters for silicon solar cells was studied. The thermal balance of a solar panel in space and the resultant effect on array efficiency was examined a specific example is studied. The physical properties and environmental characteristics of state-of- the-art coatings were studied. Measurements of the spectral transmittance, reflectance and emittance for coated cells were obtained. Environmental tests included humidity, high and low temperature storage, temperature shock, vacuum storage, and ultraviolet and beta irradiation.
