Solar grade silicon production: A review of kinetic, thermodynamic and fluid dynamics based continuum scale modeling

摘要: Abstract The rapid growth in silicon photovoltaics deployment has led to increased research focus on the energy and capital intensive refining of solar grade for improved environmental, production economic benefits. As this process consists a number steps taking place multi-phase reacting systems with complex fluid flows, models can be an important tool mechanistic understanding, design optimization. This paper reviews most widely implemented techniques classifies them into two broad categories; those relating synthesis volatile Si based compounds deposition compounds. Within each category, are further divided according reactor type or physical which they examining. These typically use computational various combinations theory obtaining chemical thermodynamics, kinetics, mechanics heat mass transfer information system. system definition, main assumptions, results study presented. There is also brief review ab initio atomistic studies area along discussion future research. work should help researchers selecting appropriate investigating developing their own models.
