June 15, 2009... Ascent Solar, a copper indium gallium diselenide (CIGS), thin-film photovoltaic module reported that the company has manufactured a monolithically interconnected 5-meter-long, flexible and light-weight module on a polyimide substrate.    Ascent Solar Sr. Vice President for Production Operations Dr. Prem Nath stated, “This is the largest monolithically interconnected CIGS module on polyimide and may be the largest of any CIGS module regardless of construction. The size and efficiency of this module make it a breakthrough for the emerging opportunities of flexible CIGS photovoltaic modules.”

The CIGS-based thin-film material in this module was made using the company’s unique 1.5 MW roll-to-roll manufacturing line. The module was encapsulated during the testing and qualification of equipment that will be used for its 30 MW plant under construction. According to the company's internal testing and evaluation, The 2-kilogram module produces 123 watts (under standard test conditions) with an aperture area efficiency of 9.1%. Ascent solar notes that the 5-meter length is a baseline for its development of large area flexible building integrated photovoltaic (BIPV) products with our strategic BIPV partners.
