Ascent Solar and CisLunar team to bring longer-lasting power solutions to US space market
Ascent Solar Technologies Inc of Thornton, CO, USA – which designs and makes lightweight, flexible copper indium gallium diselenide (CIGS) thin-film photovoltaic (PV) panels that can be integrated into consumer products, off-grid applications and aerospace applications – has signed a teaming agreement with CisLunar Industries of Loveland, CO, USA, which develops scalable hardware and embedded control software for power conversion and conditioning.
The agreement aims to bring each of the Colorado-based companies’ technologies together to achieve mutually beneficial spaceflight goals that support their competitive positioning for current and future space missions with various US space organizations including NASA, the Department of Defense, Space Force and other national security space stakeholders.
Ascent’s thin-film PV technology, paired with CisLunar’s high-efficiency power conversion technology, will support durable, long-lasting power solutions intended to keep space vehicles functional longer, thus increasing the potential mission length for commercial, civil and defense space missions. The technological union comes at a crucial time when US space organizations are actively seeking out shipment-ready, energy-efficient power solutions to bolster mission length and efficiency in a timely fashion.
“Our nation’s space leaders continue to seek out viable power solutions that they can rely on to remain functional in the face of both the punishing, natural elements of space, and the growing defense threats from foreign adversaries,” says Ascent Solar’s CEO Paul Warley. “The combination of our two technologies offers superior power systems that meet the needs of today’s space market by offering distributed power solutions that lead to improved vehicle and mission longevity,” he adds.
“By leveraging each other’s technological capabilities, industry expertise, and production capacity, CisLunar Industries and Ascent Solar offer a hungry space market a highly advantageous power solutions package,” believes CisLunar Industries’ CEO Gary Calnan. “This agreement allows each of our companies to bring a wider, more robust array of offerings to potential customers while maintaining our focus on energy efficiency and swift delivery capabilities.”
