ABSTRACT:
The invention relates to a method and device for producing polycrystalline silicon. The method consists in particular in purifying a bath of molten silicon which contains impurities by bubbling a mixture of chlorine and oxygen and in progressively crystallizing the purified silicon in a receptacle (22) which is moved vertically downwards in a vertical gradient of temperatures which increase towards the top. Application to manufacturing solar photocells.
