THORNTON, Colo., Sept. 16, 2025 (GLOBE NEWSWIRE) -- Ascent Solar Technologies (“Ascent” or the “Company”), the leading U.S. innovator in the design and manufacturing of featherweight, flexible thin-film photovoltaic (PV) solutions, today announced the signing of a teaming agreement with Emtel Energy USA (“Emtel Energy”), a provider of graphene-based electrostatic long duration energy storage (ELDES). The agreement is intended to achieve mutually beneficial goals that would advance Emtel Energy’s energy storage capabilities and aid the proliferation of thin-film PV solutions in space environments.

Emtel Energy has developed a high-agility solid-state graphene battery alternative that circumvents the low energy density and swift degradation concerns that plague flow batteries. This durable power storage technology, paired with Ascent’s thin-film PV, will be instrumental in powering satellites, spacecraft and other space architecture.

“The Department of Defense and Space Force are in great need of durable, reliable energy production and storage technologies that can withstand the punishing elements of space,” said Paul Warley, CEO of Ascent Solar Technologies. “Our lightweight, flexible thin-film PV, combined with Emtel Energy’s long-lasting energy storage technology, creates an ideal offering for these organizations as they seek out solutions that will stick around for the long haul while they continue to build out their space vehicle infrastructure.”
