[VIDEO] ICARUS – Silicon-Kerf recovery & Mono crystalline ingot growth
One of the steps of the manufacturing process of solar silicon wafers consists in shaping silicon ingots, into bricks and into wafers. Wafer slicing leads to a loss of 35% in mass and a contamination of the Silicon-Kerf. ICARUS aims to reduce the impurities by improving the sawing process and testing soft chemical and thermal treatments.
Find out more information about the recovery process of the Silicon-Kerf by CEA. The video also presents how the purified silicon-kerf could be used as feedstock material for monocrystalline ingot growth.
