PHOTOVOLTAIC
DSS™850
Crystalline Growth System
Increased Throughput Improves Productivity by 65 Percent
The GT Advanced Technologies DSS™ 850 is the newest member of the
industry’s leading family of DSS crystallization systems. The DSS850 sets a
new standard for cost-effective, precisely controlled crystalline ingot growth
and helps customers achieve lower cost of ownership and better ingot quality.
The DSS850 can grow significantly larger silicon ingots averaging 800 kg
resulting in 65 percent more output, while reducing consumable costs and
optimizing the wafer- slicing process. The design of the DSS850 will support
MonoCast™ crystal growth that offers a path to higher quality material.
GT Advanced Technologies is committed to delivering sustained value to
customers and the DSS850 delivers on this promise. Customers who operate
DSS™450, DSS™450HP and DSS™650 systems can easily upgrade their
furnaces to take advantage of the improved throughput of the DSS850.
Key Benefits:
•Furnace Output >11.5 MW per year (assumes 17% efficiency from
156 mm cell lines)
•Ingot size: 100 x 100 cm2
•Ingot weight: Typical 800 kg
•Mass ingot yield (MIY) ≥73 percent
•Cycle time ≤76 hours
•Bottom-load process chamber: adds operating convenience
•Automated and guaranteed process
•Patented crucible-coating process
•Lowest cost of ownership
•>3,200 systems of experience ensures trouble-free production ramp

Lower the Cost of Wafer Operations
GT Advanced Technologies is
The DSS850 furnace produces the industry’s largest high-volume production ingots
comprised of 36 bricks. PV manufacturers may also be able to lower the cost of
wafer operations because the taller bricks help to optimize and improve the
use of the wafer saw beam to minimize waste and improve the amount of good
wafers produced.
