The first agreement with Jiangsu Zhongneng polysilicon technology development is for GT Solar’s Trichlorosilane (TCS) production technology. The second, with Jiangsu GCL silicon material technology development, is for GT Solar’s directional solidification system (DSS) furnaces and ancillary equipment. These contracts represent the first purchases of GT Solar equipment and services by GCL-Poly and its subsidiaries.

GT Solar’s TCS production technology includes all of the technology and basic engineering services required to produce TCS, one of the primary raw materials used to manufacture polysilicon. GT Solar’s DSS furnaces are used to melt polysilicon and grow multi-crystalline ingots, which are utilized to produce solar wafers and solar cells.

Zhu Shan, executive director, chairman and CEO of GCL-Poly, said: “GCL-Poly is committed to providing high-quality and cost-competitive solar raw materials by adopting the best-in-class technologies and equipment. We chose to purchase the TCS Production Solution and DSS units from GT Solar because of their proven expertise in both polysilicon production and ingot crystallization. GT Solar’s TCS production solution should help to improve the quality and lower the cost of our polysilicon operations. Their expected timely delivery of the DSS furnaces should help to ensure that our new ingot and wafer production facility can be up-and-running in 2010.”

Tom Gutierrez, president and CEO of GT Solar, said: “We are pleased to welcome GCL-Poly as a new GT Solar customer for both our polysilicon and photovoltaic equipment businesses. Our relationship with GCL-Poly further strengthens our market position in China and reinforces our role as a technology leader. We believe GT Solar’s DSS furnaces are the system of choice for leading PV manufacturers around the world. And, our TCS Production Technology Solution represents another win for this leading technology that should help to significantly lower the production cost of polysilicon.”
