US Air Force Awards Ascent Solar High Efficiency Solar Cell Program
Ascent Solar Technologies, Inc. ("Ascent Solar") (NASDAQ:ASTI), a developer of state-of-the-art, thin-film photovoltaic materials, announced today that the US Air Force Research Laboratory (AFRL) has selected Ascent Solar for a Broad Agency Announcement award to develop high-performance thin-film multijunction photovoltaics (PV) based on Ascent Solar's flexible monolithically integrated CIGS technology. The new contract represents approximately $1.5 million in value over a 48-month period.
Since 1995, AFRL has provided funding for the development of the flexible CIGS at ITN Energy Systems, Inc. and now at Ascent Solar, including the development of aspects of future multijunction devices. Multijunction solar cells are two or more solar cells in a stack, where each solar cell collects a specific portion of the solar spectrum. The top cell in this configuration collects the blue portion of the solar spectrum, the bottom cell collects the red portion of the spectrum, and cells in between collect the rest of the visible spectrum. This type of technology can result in higher performance and lower losses when translating from the small-area cell level to monolithically integrated modules.
