Stion Announces $2M Award from Dept. of Energy SunShot Initiative

Scale-Up of Highest Efficiency Thin Film Module in Industry to Continue in CA and MS

SAN JOSE, Calif.–November 20, 2012–Stion, a leading manufacturer of high-efficiency thin-film solar modules, today announced a $2M award from the US Department of Energy’s SunShot Initiative to continue pilot production and scale-up of its ultra high-efficiency thin film modules based on proprietary tandem junction technology.

The award is a Tier 2 grant under the Sunshot’s Incubator 7 Program and is designed to accelerate the transition to commercial production. It is a follow-on to the Tier 1 award given to Stion in February 2011. As part of Tier 1, Stion successfully advanced its technology into commercial prototype stage and produced tandem junction prototype modules at 18.8% aperture efficiency, the highest for any module prototype based on thin-film technology.

“We are extremely excited to continue working with DOE to help address America’s critical need for clean, secure sources of energy”, said Chet Farris, Stion’s President & CEO. “Our progress on the tandem technology demonstrates that thin films can achieve industry-leading efficiencies on a scalable, low-cost production platform.”

Stion’s unique approach to thin film PV leverages proprietary materials and device expertise along with a robust, high-volume manufacturing process based on readily available, standardized equipment. Stion began shipments of products in March based on its single junction CIGSS technology, and has produced commercial modules with as high as 15.6% aperture efficiency.

The tandem junction module would increase efficiency by enabling broader and more effective harvesting of available light using an additional thin film device. It utilizes mechanically stacked top and bottom devices to eliminate the design and manufacturing challenges associated with traditional junction integration, and maintains the same glass / glass packaging design as Stion’s current commercial modules.

About Stion
Stion is a US-based manufacturer of high-efficiency thin-film solar modules based on state-of-the-art materials and device technology and proven production processes. Stion was founded in 2006 and is backed by leading financial and strategic investors, including Khosla Ventures, Taiwan Semiconductor / VentureTech Alliance, Lightspeed Venture Partners, General Catalyst Partners, Braemar Energy Ventures, and AVACO. Stion opened its first mass production facility in Hattiesburg, MS earlier this year. For more information, visit www.stion.com.

About DOE SunShot
The DOE SunShot Initiative is a collaborative national initiative to make solar energy cost competitive with other forms of energy by the end of the decade. Reducing the installed cost of solar energy systems by about 75% will drive widespread, large-scale adoption of this renewable energy technology and restore U.S. leadership in the global clean energy race.
