Conversion efficiency of solar cell is strongly affected by quality of substrate and the quality of substrate is influenced by melt convection if the substrate crystal is grown by melt growth technique. Therefore, melt convection control techniques are important to produce a high quality single crystal. In this paper, we have proposed a high frequency magnetic field applied CZ method and investigated the effect of high frequency magnetic field on silicon melt convection. The result reveals that the high frequency magnetic fields affect the tendency of the melt convection: until certain intensity of the high frequency magnetic field, the melt convection is suppressed and above such intensity of the high frequency magnetic field, the melt convection intensity is enhanced. This result indicates that the melt convection can be controlled by the high frequency magnetic field and the high quality silicon single crystals will be grown by this method.
