DSS™ 450 MonoCast™

Monocrystalline Growth System
A New Standard in High Quality Wafer Production
The GT Advanced Technologies DSS™450 MonoCast™ crystal growth system is the newest
member of GT’s industry leading family of silicon casting furnaces. The DSS450 MonoCast
system puts powerful DSS crystal growth technology in the hands of wafer manufacturers
allowing them to target new market opportunities that require high quality mono wafers.
Modules produced from GT’s MonoCast™ material rival modules that incorporate traditional
boron-doped batch CZ 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 traditional boron-doped
monocrystalline wafers.

GT Advanced Technologies is committed

GT’s MonoCast Advantage – Increasing the Output of Grade I Wafers

to delivering sustained value to customers

The DSS450 MonoCast furnace has a number of unique new features that result in ≥80%

and the DSS450 MonoCast delivers on this

mono volume yield per ingot*. This translates into a higher percentage of mono material

promise. Customers currently operating

per wafer which helps drive even higher efficiency at the cell and module level. For

DSS™450 and DSS™450HP systems can

customers that require uncompromised quality, GT’s innovative MonoCast technology

easily upgrade their furnaces to start

significantly increases Grade I wafers (>90% mono area/wafer) per ingot than other

producing high quality MonoCast wafers

mono-cast technologies.
