| Abstract: | The rapid development of photovoltaie industry results in lack of silicon feedstock which meets technical and economic requirements of the photovoltaic cells. More and more attentions have been paid to the research of producing solar grade silicon by refining metallurgical grade silicon. This paper surveys the recent research outcomes on directional-solidification-based upgrading of solar grade silicon by refining metallurgical grade silicon. It compares and analyzes the advances of these research outcomes to have an outlook on possible application prospect. |
| Keywords: | solar grade silicon metallurgical grade silicon refining purification directional solidification |
