Ascent Solar Technologies, Inc. is a publicly traded photovoltaic (PV) company located in Thornton Colorado. Its primary product is a flexible CIGS solar cell on a plastic substrate. Ascent Solars thin-film solar modules are manufactured from CIGS cells using copper indium gallium (di)selenide semiconductor (CIGS), which has shown a 10.5% NREL efficiency in real-world conditions. What makes this proprietary technology unique, however, is its relative size, weight and flexibility: Ascents CIGS panels currently allow for 85 watts/meter, and 48 watts/kg, thereby giving them the greatest power density and weight ratio among available flexible photovoltaic products by a significant margin. This allows for the efficient use of solar power in a range of new contexts, in which size or weight restrictions have previously rendered solar power impracticable: e.g., cell phones, airplanes, unmanned vehicles, consumer electronics, railways, space programs, and off-grid applications. This developing technology was selected as one of the 100 Most Innovative Technologies for 2010 by R&D Magazine, and as one of the 50 Best Inventions of 2011 by Time Magazine. Ascent Solar entered the manufacturing stage for its products in 2013, in part by teaming up with a range of other companies like TFG Radiant (for integrating these materials into a range of building and construction materials), Foxconn (for a "pilot project" at the Zhengzhou Factory, which is currently manufacturing the iPhone 5), and Bye Aerospace (for solar-powered unmanned aircraft).
