ARISE Technologies, which is dedicated to becoming a leader in high-performance, cost-effective solar technology, has announced that it has produced its first photovoltaic cells at its manufacturing plant in Bischofswerda, Germany using the company’s own 7N+ polysilicon.

“We have taken another significant and important step forward in our silicon feedstock development project,” said Jeff Dawkins, Vice-President and General Manager, PV Silicon Division. “This marks the first time that we have used our Silicon Refining Furnace (SiRF) to produce 7N+ high-purity silicon in a quantity that could be used to manufacture PV cells with an efficiency level comparable to those being produced at our German plant. Our current cell manufacturing process uses silicon wafers that we have purchased from other suppliers.”

ARISE’s silicon feedstock development project is being partially funded by Sustainable Development Technology Canada (SDTC). The project is developing a new approach for refining high-purity silicon needed for high-efficiency photovoltaic cells. The proprietary process that ARISE is developing is intended to produce 7N+ high-purity (99.99999 percent purity level) silicon for photovoltaic applications using a simplified chemical vapor deposition process. ARISE believes that its ability to produce 7N+ high-purity silicon will enable it to meet its target of more than 20 percent efficiency for photovoltaic cells.

“ARISE’s technology has the potential to increase efficiency while also reducing the high cost of producing PV cells, a major issue currently facing the PV solar industry,” said Vicky J. Sharpe, President and CEO of SDTC. “The achievement of this significant milestone in the silicon feedstock development project represents an important step forward for the PV solar industry in Canada and around the world.”

“Having achieved this milestone in our development program, ARISE is displaying at the 24th European Photovoltaic Solar Energy Conference and Exhibition being held in Hamburg, Germany September 21-25 mono-crystal ingots that we produced from our polysilicon,” Mr. Dawkins reported.

ARISE Technologies, based in Waterloo, Ontario, is dedicated to becoming a leader in high-performance, cost-effective solar technology. The company operates through three divisions. The PV Cell Division manufactures photovoltaic cells at its first manufacturing plant opened in April 2008 in Bischofswerda, Germany. The division is developing proprietary technology with a target of achieving a step-by-step progression to a high-efficiency level of greater than 20 percent. The PV Silicon Division is using a proprietary method to produce silicon at 7N+ high-purity (99.99999 percent) for photovoltaic applications, based on a simplified chemical vapour deposition process. The division is focusing on scaling up its process to provide ARISE with control over its supply, costs, and quality. The PV Systems Division has been providing photovoltaic solutions for solar farms and rooftop installations since 1996 throughout North America. With the new Green Energy and Green Economy Act and the Ontario FIT (Feed-In-Tariff) program, ARISE is planning to expand its Systems business in Ontario.
