3D time-dependent numerical study of the influence of the melt flow on the interface shape in a silicon ingot casting process

Carbon concentration and particle precipitation during directional solidification of multicrystalline silicon for solar cells

“…With the development of modern computer technology and efficient algorithms, numerical simulation has been developed as a powerful tool for analysis and optimization in the field of crystal growth and solidification [9][10][11][12][13][14]. However, there have been few reports [15] on numerical simulation of carbon segregation and SiC particle precipitation in a directional solidification process.…”

Study on thermal stress in a silicon ingot during a unidirectional solidification process

“…Many studies on optimization of a unidirectional process of crystalline silicon for solar cells have been carried out [3][4][5][6][7][8][9][10][11]. Liu calculated time-dependent distribution of iron and temperature [3], carbon concentration and SiC particle precipitation [4] in a silicon ingot.…”

“…Liu calculated time-dependent distribution of iron and temperature [3], carbon concentration and SiC particle precipitation [4] in a silicon ingot. The melt-solid interface shapes of a silicon ingot in unidirectional solidification and casting processes were studied by Vizman et al [5] and Miyazawa et al [6,7]. The relative movement of various parts of furnace was considered in a global 3D time-dependent numerical simulation by Delannoy et al [8].…”

Numerical Study of the Thermal and Flow Fields during the Growth Process of 800 kg and 1600 kg Silicon Feedstock

“…Due to the confidentiality policies of the company with which we are working in cooperation, the operating conditions are not specified. It is known that performing 3D simulation will predict more exactly the evolution of flow and thermal field during the growth of ingot [6,11,12]. However, 3D modeling is complex and time consuming, especially for the large size of ingot and the transient computation.…”
