Marlboro, Massachusetts (USA), September 24, 2007 - Evergreen Solar, Inc. (Nasdaq: ESLR) today announced it is featuring its revolutionary new Quad furnace technology at its exhibit during the Solar Power Conference in Long Beach, California (September 25-27). The ground-breaking innovation evolved from Evergreen's proprietary String Ribbon' technology. Quad furnace operations will increase manufacturing and product efficiencies while strengthening String Ribbon's' status as a scaleable, exportable technology.
"Our new 75-MW factory in Massachusetts (USA) will use our revolutionary Quad furnace technology with its state of the art automated ribbon-cutting technology," said Rick Feldt, President and CEO of Evergreen Solar. "This innovative wafer production process provides substantial opportunity to further increase yield, cell efficiency and labor productivity as well as to reduce our already industry-leading silicon consumption."
Feldt said that in addition to substantially augmenting Evergreen's manufacturing and product efficiencies, Quad technology also improves the Company's industry-leading environmental credentials. The advanced furnace further reduces the carbon footprint of Evergreen panels, which is already the smallest of any panel on the market.
In the String Ribbon' process, a set of special parallel strings are pulled continuously through a small molten pool of silicon inside a custom furnace. A thin "ribbon" is created between the two strings as the silicon cools and re-crystallizes. The ribbon is then cut into wafers, which are converted into solar cells and used in the production of solar panels - all under one roof. The process is continuous, clean and efficient. Evergreen's current String Ribbon' technology produces two ribbons at one time, while Quad creates four ribbons simultaneously.
