ASTI Ascent Solar Technologies Inc

Ascent Solar Technologies, (Nasdaq: ASTI) (“Ascent” or the “Company”), the leading U.S. innovator in the design and manufacture of featherweight, flexible, and durable CIGS thin-film photovoltaic (PV) solutions, today announced it has begun developing prototype solar arrays in collaboration with the University of Stuttgart Institute for Building Energetics, Thermotechnology and Energy Storage (IGTE), an international research center focused on energy storage, renewable energies and indoor climate technology.

Though the project details are not yet publicly available, Ascent will likely ship its ultralight, highly durable and flexible thin-film technology this summer to meet IGTE’s timeline for developing its power collection and storage systems.

“Ascent continues to establish partnerships that put our proprietary CIGS thin-film tech in the hands of top-tier organizations – like the University of Stuttgart IGTE - as they work to spur the next wave of sustainable power generating technology,” said Paul Warley, CEO of Ascent Solar Technologies. “The institute has incredible capacity for system development, testing and investigation, and we look forward to seeing what they can conceive, construct and deploy utilizing Ascent’s technology.”

The IGTE mission is to “research and teach for comfortable living and working conditions in buildings and quarters in harmony with energy efficiency, sustainability and technology. Particular emphasis is placed on renewable energies…and using top-tier scientists to develop sustainable solutions for the global transformation of energy systems.” Since its establishment in 2018 the IGTE has continued to expand and develop innovative solutions for energy generation and storage with the intent for wide scale distribution and adoption.
