Chapter Seven - Crystalline Silicon Feedstock Preparation and Analysis

Laszlo Fabry; Karl Hesse

Abstract We review and evaluate historical, present, and future trends in high-volume manufacturing (HVM) processes for polysilicon solar feedstock. Witnessing expanding HVM closed-loop capacities based on the purification of metallurgical silicon on the gaseous phase and chemical vapor phase deposition of chlorosilane precursors according to the Siemens process, we provide an interpretation of this trend. Analytical methods for quality assurance and quality assessment are also presented.
