INVESTIGATION OF OPTICAL COATINGS FOR SOLAR CELLS

Abstract

The use of spectrally selective coatings as filters for Si solar cells is under investigation with primary emphasis on auxiliary power systems for space vehicles. A general study of the thermal balance of a solar panel in space and the resultant effect on array efficiency were examined. The diffuse spectral reflectances and spectral sensitivities of typical Si cells are being redetermined. The physical properties and environmental characteristics of state-of-theart coatings are being studied and measurements of the spectral transmittance, reflectance and emittance for cell coatings are being obtained. Environmental tests included humidity, high- and low-temperature storage, temperature shock, vacuum storage and UV and beta irradiation. Adaptation of the Spectrolab IR window coating to Si solar cells is being studied. (Author)
