A new production process of solar-grade silicon (SOG-Si) for small demand which is made from metallurgical-grade silicon (MG-Si) is proposed here, based on the findings of silicon refining stage in NEDO (New Energy and Industrial Technology Development Organization) Direct Reduction Process. SOG-Si trially produced was made into a multicrystalline cell through NEDO Project and the conversion efficiency was max. 10.9%.

Removal of boron from molten silicon was investigated using Ar plasma mixed with water vapor in view of developing a new process for solar-grade silicon (SOG-Si). The raw silicon was induction-melted and blown with a plasma flame of Ar gas with water vapor. It was concluded that the concentration of boron in silicon was decreased from 20 ppmw down to 0.1 ppmw or less by the plasma treatment for 300 minutes, and the rate of removing boron is proportional to both of the concentration of H2O in Ar plasma and the reaction area on the molten surface formed by blowing of the plasma. Presumably, the boron atoms were removed as volatile boron oxides. The kinetic analysis revealed the first order character of the reaction.
