Our focus is to understand the processes needed for the production of high quality silicon ingots. Thorough validation of the models is based on the close interaction with experimental activities.

• Heat transport processes
• Conduction
• Radiation
• Forced and natural convection
• Solidification
• Mass transport and related
  issues
• Melt convection
• Segregation
• Impurity transport in the
  melt/ingot and cover gas
• Impurity dissolution/evaporation from crucible/coating/cover gas
• Inclusions and particle precipitation
• Stress analysis
• Dislocation multiplication
• Residual stresses
• Impact of impurities and dislocations on minority carrier lifetime
