OTB Solar and ARISE Technologies announce significant progress in development and deployment of innovative selective emitter approach

Eindhoven, October 8, 2009 – OTB Solar and ARISE Technologies Corporation (TSX: APV and Frankfurt: A3T), which is dedicated to becoming a leader in high performance, high quality, cost-effective solar technology, today announced that their cooperation has resulted in significant progress in the development and deployment of OTB Solar's Single Pass Selective Emitter Process, in combination with a conventional P-doper diffusion furnace, to produce high efficiency silicon based photovoltaic cells.

The Single Pass Process enables the deposition of the area emitter and selective emitter dopants in a single pass process sequence, thus reducing and eliminating the need for additional costly emitter forming equipment, processes and materials. The emitter forming process under development at OTB Solar's Eindhoven Technology Center and ARISE’s Bischofswerda PV Cell Production Fab utilizes OTB Solar's ELEMENTS Ink Jet Printing Deposition Platform. This industrial scale product can be easily adjusted towards the different throughput requirements of cell makers. "Recent developments indicate that a significant improvement in cell effect can be attained by way of a single pass Selective Emitter Process. The process is simple, cost effective and can be easily integrated into existing cell production operations,” says Paul Breddels, CEO of OTB Solar.

Ian MacLellan, Vice Chairman, President of Systems Division and CTO of ARISE Technologies stated, “We have been looking at various selective emitter approaches and like this one because it is simpler to implement in production while keeping existing throughput on our production lines. These low volume results also demonstrate that we can implement this technology on our existing production lines. We look forward to working with OTB to develop a high volume solution to complement our strategy of a step by step approach to delivering on our high efficiency program for our customers and shareholders.”

About ARISE Technologies

ARISE Technologies Corporation, 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 PV (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%. The PV Silicon Division is using a proprietary method to produce silicon at 7N+ high-purity (99.99999% purity) for PV cell applications, based on a simplified chemical vapor 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 PV solutions for solar farms and rooftop installations since 1996 throughout North America. ARISE is planning to expand its Systems business in Ontario under the Ontario FIT (Feed-In-Tariff) program. The company's shares are listed on the Toronto Stock Exchange under the symbol APV and on the Frankfurt Open Market Exchange under the symbol A3T.
