The analysis covers the fabrication and test of photovoltaic materials and design of solar-cell arrays for maximum conversion of solar energy with minimum weight. Evaporated layer cells with an efficiency of up to 4.5 percent over anAREA OF 1.6 SQ CM WERE FABRICATED. Research on crystal layer conversion reduced the temperature for recrystallization from 500 C to 300 C. Two models of solar-cell arrays to simulate a 100 sq ft system were fabricated the tele coping sail with a density of 0.075 lb sq ft., and the inflatable torus sail with a density of 0.04 lb sq ft. The maximum area of individual cells was increased by a factor of 27, thickness of substrate reduced by factor of 6, and weight reduced by factor of 7.
