Title
Polysilicon production - Modelling and Scaleup
Abstract: Silicon based photovoltaic (PV) cells are expected to play a major role in the utilization of solar energy and the market for polysilicon is expected to grow rapidly in the next decade. Large scale production with capacity per plant of 10 000 mt/year or more are expected to be the norm in order to reduce the cost of production improve the energy efficiency and the by-product recovery and reuse in such processes. The reactor design and scaleup of these systems therefore becomes important. This needs a multiscale modeling methodology which encompasses the fields of chemical kinetics particle nucleation and growth hydrodynamic models and reactor models. Simultaneously process intensification and optimization tools need to be developed. The focus of this talk is to provide a review of the current technologies and recent advances in polysilicon production and modeling. It is hoped that the information and the key references provided will be useful to identify areas for future research and educational needs in this field.
