Floating Substrate Process. Large-Area Silicon Sheet Task, Low-Cost Solar Array Project. Final report

Description: The work described was directed toward the demonstration of the practical feasibility of the Floating Substrate Process for the growth of silicon sheet. Supercooling of silicon--tin alloy melts was studied. Values as high as 78/sup 0/C at 1100/sup 0/C and 39/sup 0/C at 1200/sup 0/C were observed, corresponding to supersaturation parameter values 0.025 and 0.053 at 1050/sup 0/C and 1150/sup 0/C, respectively. The interaction of tin with silane gas streams was investigated over the temperature ra… more

New developments in the IZG of metal oxide-metal eutectic composites

Description: Hartzell and Sekerka's numerical analysis of internal zone growth (IZG) has been used to interpret the problems of surface melting, difficult initial Rf-coupling, and heating controllability. By varying the parameters suggested by their analysis, solutions were found to all three problems as encountered in the IZG of Cr/sub 2/O/sub 3/--Mo eutectic composites. A new sample preparation technique was developed which allows Rf-coupling at room temperature and improved heating control.

Laser-zone growth in a ribbon-to-ribbon (RTR) process silicon sheet growth development for the large area silicon sheet task of the low cost silicon solar array project. Technical quarterly report no. 8, April 1--June 30, 1978

Description: Further progress in growth rate has been made, reaching an area throughput rate of 38 cm/sup 2//min. This growth rate was achieved, using CVD feedstock, both with a 7.6 cm wide ribbon grown at 5 cm/min and a 5 cm wide ribbon grown at 7.6 cm/min. The 5 cm wide ribbon exhibited a dendritic structure; although the ribbon showed a tendency to buckle in the non-dendritic region, it was perfectly flat once the dendrites were firmly established. The 7.6 cm wide ribbon was non-dendritic, and had severe… more
