Research summary:

Production of high-purity silicon for solar cells and  electronics can be done through several routes. Although the  trichlorosilane-based Siemens process is dominating the industry today there  is reason to believe that monosilane-based processes and upgraded  metallurgical silicon will take over in the long run. This paper will give a short description of the status on research and  development on monosilane-based polysilicon production technologies.  Furthermore we will summarize some of our experiences as an independent research facility for silicon production and demonstrate some results on how  pilot reactor testing, on-line monitoring and process control improves  silicon production technologies.
