Description

The overall objective of the LSA Silicon Material Task is to establish a chemical process for producing silicon at a rate and price commensurate with the production goals of the LSA project for solar-cell modules. This material must be suitable for utilization in the large-area sheet process and in the automated process for the fabrication of solar cells. As part of the overall Silicon Material Task, Union Carbide developed the silane-silicon process and advanced the technology to the point that it has a definite potential for providing high-purity polysilicon on a commercial scale at a cost of $14/kg by 1986 ... continued below

Description

The overall objective of the LSA Silicon Material Task is to establish a chemical process for producing silicon at a rate and price commensurate with the production goals of the LSA project for solar-cell modules. This material must be suitable for utilization in the large-area sheet process and in the automated process for the fabrication of solar cells. As part of the overall Silicon Material Task, Union Carbide developed the silane-silicon process and advanced the technology to the point that it has a definite potential for providing high-purity polysilicon on a commercial scale at a cost of $14/kg by 1986 (1980 dollars). The Phase III program (initiated in April 1979) is aimed at establishing the practicality of the process by pursuing the followng specific objectives: (1) design, fabricate, install, and operate an Experimental Process System Development Unit (EPSDU) sized for 100 MT/Yr to obtain extensive performance data to establish the data base for the design of commercial facilities; (2) perform supporting research and development to provide an information base usable for the EPSDU and for technological design and economic analysis for potential scale-up of the process; and (3) perform iterative economic analyses of the estimated product cost for the production of semiconductor-grade silicon in a facility capable of producing 1000 MT/Yr. The three basic process steps entail converting M-G silicon to trichlorosilane, redistributing the trichlorosilane to produce silane, and thermally decomposing the silane to form polycrystalline silicon powder. The powder is then melted and the molten silicon is cast into rods for subsequent fabrication of solar cells. Technical progress is reported. (WHK)
