GT Solar Achieves Record for Average Solar Cell Efficiency

GT Solar International, a global provider of polysilicon production technology, and sapphire and silicon crystalline growth systems and materials for the solar, LED and other specialty markets, today announced that researchers at Georgia Institute of Technology have demonstrated average cell efficiencies of 18.8% with highest efficiencies exceeding 19% on monocast silicon material grown in GT’s advanced ingot casting furnace.

“The efficiency results announced by Dr. Rohatgi’s team on cells produced with our monocast material are very satisfying,” said Tom Gutierrez, president and CEO of GT Solar. “Our advanced technology team and material scientists have been focused on balancing casting furnace architecture with refined process techniques to produce material that demonstrates near monocrystalline silicon performance and leverages the low cost advantages of multicrystalline production. These recent results indicate we are making great progress in achieving this goal and we fully expect to offer this for commercial availability later in the year.”
