Book Description
During this reporting period, major activities were continued on process system properties, chemical engineering and economic analyses for application to alternate processes under consideration for solar cell grade silicon. In Task 1, primary efforts were devoted to properties of silicon source materials. For silane, liquid viscosity data were correlated as a function of temperature to cover the entire liquid range. Estimates for gas and liquid thermal conductivity are reported. For Task 2, major efforts were devoted to preliminary process design for the conventional polysilicon process based on the rod reactor (hairpin) technology. The criteria for design were selected to be commensurate with the design basis for the alternate processes to produce solar cell grade silicon. Chemical engineering analysis activities in Task 2 also focused on preliminary process design for a silane (SiH/sub 4/) plant. A revised flowsheet received from Union Carbide has received a preliminary review, and process design has been reinitiated. In Task 3, preliminary cost analysis is in progress for the conventional polysilicon process used in the United States and Europe for the production of semiconductor grade polysilicon. Plant investment and product cost estimates will be determined upon completion of review of major process equipment and production labor requirements.
