Equipment Solutions for Multi-crystalline Ingot Production
GT Solar, a market leader in multi-crystalline growth technology, offers an evolving line of products designed to enhance performance and lower cost.
Our Directional Solidification System (DSS) furnaces, specialized furnaces that melt polysilicon and cast multi-crystalline ingots, are used to produce solar wafers, which are key components of solar cells. Our DSS furnaces are the most widely used in the solar industry, with more than 1,000 units shipped worldwide.
GT Solar’s key multi-crystalline growth products are:
DSS450HP™ DIRECTIONAL SOLIDIFICATION SYSTEM
Increased Productivity Lowers Cost of Manufacturing
Distinguished by its proven production technology, GT Solar’s DSS450HP furnace sets the standard for cost-effective, reliable multicrystalline ingot growth and helps customers lower the cost of PV manufacturing. The GT Solar DSS450HP includes a thermally optimized, second-generation hot zone for improved efficiency that can grow significantly faster silicon ingots averaging 52 hours — resulting in 15-20 percent more throughput. Because the DSS450HP has the same dimensions as the DSS450, current users can easily migrate to the new DSS450HP with a field upgrade kit. As a leading provider of PV manufacturing technology and services with over 1300 DSS systems in the field, GT Solar delivers proven value
and a high return on investment.
Key advantages include:
• Cycle time down to 52 hrs*
• Mass ingot yield greater than 65%*
• >1,300 systems of experience ensures trouble free production ramp
• Furnace Output > 8MW per year (assumes 15.8 percent efficiency from 156 mm cell lines)
• Fully automated and guaranteed process
• Patented crucible coating process
• Capability to process low and high quality feedstock
• Bottom-load process chamber adds operating convenience
• Upgrade kits available for DSS240™ and DSS450
*Using 430 kg solar grade feedstock
Lowering the Cost of Manufacturing
The high-throughput DSS450HP furnace produces large ingots rapidly – down to 52 hours – resulting in a 15-20 percent improvement in productivity. Silicon is directionally solidified into a square ingot and later cut into 25 bricks. GT Solar’s innovation and expertise in mechanical design, vacuum and high-pressure chambers, control system design, and crystal growth modeling, provide customers with a technologically advanced system that consistently produces high quality ingots that optimize mass ingot yield.
Existing DSS450™ and DSS240™ customers can easily upgrade to the new DSS450HP platform with a simple field upgrade kit that quickly gets them up and running to take advantage of the new levels of throughput and cost savings.

GT-FZ100™
Float Zone System
Float zone is widely used by silicon manufacturers for analytical lab sample preparation and quality control. It plays an important role in assuring material purity, and is therefore an essential tool for solar and semiconductor grade silicon manufacturing.
GT Solar's GT-FZ100 float zone system has a long history of providing fast turn-around sampling and batch check for every reactor run, and for helping our customers ensure they are producing high quality silicon. The GT-FZ100's extreme reliability and stellar performance are evidenced by the many repeat orders we have received from satisfied GT Solar customers around the world.
