METHOD AND APPARATUS FOR PRODUCING SILICON, SILICON WAFER AND PANEL FOR SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a silicon production method capable of surely bringing a treating agent into contact with molten silicon in the case of removing impurities in molten silicon with the treating agent, thereby efficiently contributing to the reaction with impurities.

SOLUTION: The silicon production method comprises a pushing step of pushing the treating agent into the system at a level lower than the liquid level of the molten silicon in the system and a removal step of reacting the impurities in the molten silicon with the treating agent and removing the impurities from the system.
