GT Advanced Technologies Inc. announced the commercial availability of its DSS(TM)450 MonoCast(TM) crystal growth system. Modules produced from material grown in GT's DSS(TM)450 MonoCast(TM) furnace rival modules that incorporate traditional boron-doped batch CZ monocrystalline wafers in terms of total output. The DSS450 MonoCast furnace incorporates a number of new features that result in >=80% mono volume yield per slabbed ingot and significantly increases Grade I wafers (>90% mono area/wafer) per ingot than other cast mono technologies. The MonoCast(TM) technology is being offered first on GT's DSS450 and DSS450HP systems. Customers currently operating these DSS furnaces can migrate to the new DSS450 MonoCast system through a field upgrade. GT's DSS(TM)450 MonoCast(TM) crystal growth system. Modules produced from material grown in the DSS450 MonoCast furnace rival modules that incorporate traditional boron-doped batch CZ monocrystalline wafers in terms of total output. Modules produced from GT's MonoCast material rival modules that incorporate traditional boron-doped batch CZ processed monocrystalline wafers in terms of total output. Cells produced from DSS450 MonoCast wafers have lower Light Induced Degradation (LID) and the full square surface dimension area across the wafer provides greater electricity generating surface area than the pseudo square shape of traditional monocrystalline wafers. The result is module efficiencies that are competitive with modules incorporating batch monocrystalline wafers. The DSS450 MonoCast features new advanced hardware and an industry first automatic seed retention feature that eliminates dipping and operator intervention between melt and growth helping to automate the process and enabling the production worthiness of the DSS450 MonoCast system. When combined with GT's new Acuity(TM) performance software, the DSS450 MonoCast can produce high quality ingots run after run.
