DayStar Technologies Achieves Advanced Performance Milestones With Discrete CIGS Solar Cells on Metal Foils

Achievements Validate GEN IIITM Process Feasibility and TerraFoilTM Product Capability

Halfmoon, NY – (PR Newswire) – June 15, 2006 – DayStar Technologies, Inc. (NASDAQ: DSTI), a developer and manufacturer of innovative Photovoltaic FoilTM  products, today revealed key performance milestones on TerraFoilTM cells produced using each of its three production line processes.  As an alternative to wafer Silicon cells, DayStar’s TerraFoilTM cells 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 (1.1 cm2) glass substrates and 15.7 percent on flexible metal substrates.  Similar size TerraFoilTMcells made 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 IIITM production platform.

“These results further advance this year’s mission of demonstrating product efficacy and 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 our Gen IIITM process,” 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 IIITM tools 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 IIITM, 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, TerraFoilTM cells 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 Photovoltaic Foil™ that converts sunlight into energy. The Company manufactures CIGS solar cells, which are deposited on flexible metal foils using production processes adapted from computer component manufacturing. 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.
