Thornton, Colo. Ascent Solar Technologies, Inc. (NASDAQ:ASTI), a developer of state of the art flexible thin-film solar modules, announced today that SkySentry, a high altitude vehicle developer n Airship Manufacturer headquartered in Colorado Springs, Colorado, received their first flexible CIGS PV array for an upcoming aerostat test in Sandusky, Ohio, scheduled for mid-September, 2009.dd

Charles Lambert, President and CEO of SkySentry, stated he finds power production and storage to be the most difficult challenge of operating stationary vehicles for lengthy periods in the stratosphere. This test will use an aerostat, a tethered blimp, to characterize performance of a solar array on a dynamic platform, understand the performance of thin film arrays on buoyant vehicle in terms of temperature and impact on an inflated substrate, determine the consistency of solar output for high altitude applications and quantify the effect of clouds and variable weather on performance of an aerostat-mounted array. Corollary benefits include comparing high efficiency solar array deployments on aerostats as primary or supplementary power generation with other technologies such as off-shore power generation with wind turbines.

- measured performance over specifications
- provide higher specific power than available elsewhere
- beginning integration onto aerostat for fligiht on _____

Dr. Joseph Armstrong, Chief Technical Officer, added. This shipment represents our first delivery of flexible monolithically integrated CIGS PV specifically for airship experimentation. SkySentry's testing of our photovoltaics on the aerostat, along with advanced power management, will demonstrate their approach towards an important application for national security and surveillance applications.
