Numerical Simulation of the Optimized Hot Zone
Structure of the Multi-Crystalline Silicon Directional Solidification Furnace for Photovoltaics
Abstract: The hot zone of the directional solidification multi-crystalline silicon furnace is extremely important to the quality of multi-crystalline silicon. In this paper, numerical simulation was carried out by using CGSim on the added heat preservation structures in the bottom edges and sidewalls of the hot zone and its effects on the temperature field, flow field and interface were analyzed. Simulation results show that, after the optimization of the hot zone, isotherms around the bottom edges and the sidewalls become flat and the flow of the molten silicon is better to remove the impurities. Therefore, the quality of the multi-crystalline silicon by directional solidification is improved.
