Ascent Solar Announces Resignation of Director.

LITTLETON, Colo. -- Ascent Solar Technologies, Inc., (NASDAQ:ASTI) (BSX:AKC) announced today that Mark Waller resigned from its Board of Directors effective November 30, 2006. The company will immediately begin a search for a candidate to fill the vacant Board position.

In his letter of resignation, Mark Waller stated, "It has been a real pleasure to serve as a Director on the Ascent Solar Board and I am certain the company will continue to make great strides forward. Unfortunately, my position as a member of the Ascent Solar Board has become too restrictive and potentially conflicting with my principal business as a financial advisor to other companies particularly within the energy sector. I feel it is appropriate for me to depart at this time so that I can more freely pursue opportunities within the exciting and growing field of energy." Ascent Solar plans to use Mr. Waller's services from time to time on a consulting basis.

Ascent Solar President and CEO Matthew Foster stated, "We are saddened by Mark's departure, but we also understand his decision and commend his integrity and high standards of business conduct. Mark has been an invaluable resource who has served Ascent Solar in exceptional fashion from its very beginnings. He will be greatly missed as a director, but we look forward to retaining him as a consultant to the company."
