<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for producing low-cost silicon polycrystals for solar cells. <P>SOLUTION: In the method for producing silicon by reducing a chlorine compound of silicon, at least, a metal is made into liquid particles, and the liquid particles of the metal are brought into contact with a gaseous chlorine compound of silicon to reduce the chlorine compound of silicon in order to produce silicon. The apparatus for producing silicon comprises: at least a reactor in which particles of a metal and a gaseous chlorine compound of silicon are reacted with each other; a means to heat the reactor; a means to feed particles of the metal into the reactor; a means to feed the chlorine compound of silicon into the reactor; a means to discharge fluid in the reactor; and a vessel for capturing generated silicon. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
