DEVICE FOR REFINING OF SILICON BY DIRECTIONAL SOLIDIFICATION IN AN OXYGEN-CONTAINING ATMOSPHERE AS WELL AS A REFINING METHOD OF SILICON

摘要

There is provided a device for a directional solidification process in particular of liquid silicon to produce solar grade silicon as well as the refining method for directional solidification. The device comprises a furnace with heating elements that tolerate an oxygen-containing atmosphere and are arranged above a bottom plate, wherein on the bottom plate a crucible/mould with liquid silicon is placed on. In addition, there are provided a method of the directional solidification, a computer readable medium on which computer software is stored on and a program element for the operation of the device for directional solidification.
