Patent ID: 8461487

Claim:
A system for forming high quality silicon material for solar cells, the system comprising: a crucible having an interior region, the crucible being made of a quartz material, the quartz material being capable of withstanding a temperature of at least 1400 Degrees Celsius, the crucible being configured in an upright position and having an open region to expose a melted material; and an independent injecting device configured above the crucible, the independent injecting device an energy source and a purifying material supply system, wherein the energy source comprising an arc heater configured above the open region and spaced by a gap between the exposed melted material and a muzzle region of the arc heater to cause formation of a determined temperature profile within a vicinity of a center region of the exposed melted material while maintaining outer regions of the melted material at a temperature below a melting point of the quartz material of the crucible, and wherein the purifying material supply system comprising a chemical and gas supply tube and a high pressure gas supply tube, the chemical and gas supply tube being configured to provide chemicals and gases required for purification, the high pressure gas supply tube being configured to provide high-pressure damped gas mixtures.
