DENDRITIC SILICON SOLAR CELL OPTIMIZATION AND FABRICATION.
Abstract
This report describes the research and development work to optimize and fabricate dendritic silicon solar cells in the areas related to weight reduction, physical and electrical characteristics, and radiation resistance. A total of 970 diffused standard cells and 901 epitaxial drift field cells of 1 by 30.5 cm size were fabricated. The efficiency range of the standard cells was 9.0 to 13.3 percent with a mean of 10.5 percent, and the range of the drift field cells was 9.0 to 12.7 percent with a mean of 10.6 percent. The cell efficiencies are based on tungsten 100 mw/sq cm. Physical and electrical properties based on typical cell characteristics related to illumination intensity, spectral response, temperature, and radiation resistance are given. Process specifications for cell fabrication are included. Integral quartz coatings of at least .001 inch thickness were evaluated and are discussed briefly.
