Daystar Technologies Achieves Advanced Performance Milestones With Discrete Cigs Solar Cells On Metal Foils

Halfmoon, NY — (PR Newswire) — June 15, 2006 — DayStar Technologies, Inc. (NASDAQ: DSTI), a developer and manufacturer of innovative Photovoltaic Foilä products, today revealed key performance milestones on TerraFoiläcells produced using each of its three production line processes. As an alternative to wafer Silicon cells, DayStar’s TerraFoiläcells have the potential to dramatically lower photovoltaic module costs below current levels, which could significantly expand the market and accelerate the use of solar power systems worldwide.


Recent results from measurements performed in DayStar’s characterization laboratory have shown solar cells produced from its Gen I line achieved 16.9 percent total area conversion efficiencies on (1.1cm2) glass substrates and 15.7 percent on flexible metal substrates.  Similar size TerraFoiläcellsmade on their commercial-scale Gen II platform have achieved 13 percent efficiencies.  However, the most significant achievement was the demonstration of a 13.5 percent larger area device (14 cm2) produced using processes being developed for their high-capacity Gen IIIäproduction platform.


“These results further advance this year’s mission of demonstrating product efficacyand are very encouraging as we enter into commercial scale production with Gen II,” commented Jack McCaffrey, Vice President of Manufacturing, DayStar Technologies.


“The larger area cell performance achieved clearly demonstrates the viability of ourGen IIIäprocess,” said Bob Weiss, Vice President of Advanced Technologies of the Equipment Development Group located in Santa Clara, California.  “We are rapidly incorporating these process results to complete the design of our first Gen IIIätools and remain confident in our timelines.”  


DayStar has engaged in a multi-generational solar cell development and production strategy.  The Company presently operates two separate cell lines (Gen I and Gen II) in their Halfmoon, New York facility as a means of demonstrating product capability and low volume manufacturing techniques.  Volume manufacturing and increased capacity will occur with the development and operation of their more advanced Gen IIIä, roll-to-roll production platform, planned for implementation in early 2007.  Each line is used to advance the performance and manufacturability of the Company’s unique discrete CIGS solar cells.  Unlike other non-Silicon thin film production processes incorporating monolithic module designs, TerraFoiläcells can be used by the existing flat- plate PV module industry, hungry for an alternative to Silicon solar cells, predicted to be in short supply through 2010 and possibly beyond.

About DayStar Technologies, Inc.

DayStar Technologies, Inc. is an emerging leader in low cost, high efficiency PhotovoltaicFoil™ that converts sunlight into energy. The Company manufactures CIGS solar cells, which are deposited on flexible metal foils using production processes adapted from the semiconductor and magnetic drive industries. As an alternative to wafer-silicon solar cells, DayStar believes the unique combination of its CIGS solar cell design coupled with proprietary manufacturing processes on flexible metal substrates could substantially lower costs and remove deployment barriers currently limiting large adoption of solar energy.  For more information on the Company, please visit
