Specifically Designed for High Altitude Airships, Winged Unmanned Aerial

Vehicles and Orbital Applications for Next Generation Satellite Craft

HALFMOON, N.Y., March 3 /PRNewswire-FirstCall/ \-- DayStar Technologies,

Inc. (Nasdaq:
[DSTI](http://studio.financialcontent.com/Engine?Account=prnewswire&PageName=QUOTE&Ticker=DSTI)),
a developer and manufacturer of patented and proprietary

high performance, silicon-free solar cells on specialty metal foils,
today

unveiled LightFoil(TM) for high specific power applications. This
proprietary

alternative energy solution is the first of many highly anticipated

Photovoltaic Foil products expected from DayStar.

Military and Homeland Security applications for LightFoil(TM) include
high

altitude airships (HAA), winged unmanned aerial vehicles (UAV), and
orbital

applications for next generation satellite craft. The product meets the
low

weight, high power, and form flexibility metrics required by onboard
power

generation systems for these weight sensitive applications.

LightFoil(TM) consists of high efficiency CIGS solar cells deposited on

thin titanium foil. Less than the thickness of common household aluminum
foil,

LightFoil\'s design allows for high power production from sunlight
without

excessive weight. The Company has achieved a specific power level of
1440 W/kg

(15.2% AM0 efficiency) in the laboratory setting, which is approximately
50%

more energy dense and 60% lighter than all known thin film alternatives.

Manufacturing development of LightFoil(TM) based on the laboratory
benchmark

is currently underway with a specific power target that will exceed 1000
W/kg.

Engineering samples should be available in 2Q 2005.

In addition to high specific power, LightFoil(TM) is also flexible both

physically and in form factors. The product molds to curved surfaces and
can

be cut to shape to conform to complex geometric requirements.

\"LightFoil(TM) is specifically designed to meet the unique challenges

posed by stratospheric airships, other UAV\'s and orbital craft,\"
stated

Dr. John Tuttle, DayStar\'s CEO. \"Without the constraints of adapting
an

existing silicon-based product manufacturing line, we were free to
produce a

low cost, lightweight product which exceeds specific power requirements
in

many cases. As a consequence, DayStar is able to dedicate manufacturing

capability specifically for LightFoil(TM), should demand warrant.\"

To achieve cost and quantity benchmarks, the Company produces its

Photovoltaic Foil products using proprietary, low cost, high volume

manufacturing processes adapted from commodity computer component

manufacturing. As a result, LightFoil(TM) is not only lightweight with
high

power but also cost effective for specialized military, homeland
security and

commercial applications.

About DayStar Technologies, Inc.

DayStar Technologies, Inc. is a global leader in low cost, high
efficiency
