Abstract

Two-dimensional mathematical modeling of solid-liquid interface during directional solidification of polycrystalline silicon is established by analytic method. This mathematical model quantitatively reveals the mathematical principle of the solid-liquid interface and can be used to analyze the key parameters affecting the interface morphology. The results of modeling indicate that the interface morphology is related to the boundary temperature distribution of the interface and the heat flux of the crucible sidewall, and the latter is the key factor affecting the interface morphology.
