DSS™450 MonoCast™
Monocrystalline Growth System
Increasing the Output of Grade I Wafers
DSS™450 MonoCast is the latest addition to GT’s industry leading DSS™ family.
The DSS™450 MonoCast™ can achieve mono volume yield that is greater than 80% of the ingot*. That translates to more mono region per wafer which helps drive even higher efficiency at the cell and module level. And for customers that seek uncompromised quality, the DSS™450 MonoCast™ can produce up to 50% more Grade I wafers (>90% mono area) than other industry solutions.
Cells made with MonoCast™ wafers have lower Light Induced Degradation (LID) and offer additional area from their full square form. This can produce higher efficiency modules comparable to monocrystalline modules made from boron-doped batch CZ monocrystalline material.
GT’s market-leading expertise in crystal growth processes, mechanical design, vacuum and high-pressure chambers, control system design, and crystal growth modeling, provide customers with a technologically advanced system with production proven repeatability. The DSS450 MonoCast features an industry first automatic seed retention feature that eliminates operator intervention at the end of melt and the start of growth. Coupled with GT’s Acuity™ software, the DSS450 MonoCast can produce high quality ingots from run to run and furnace to furnace.
