Ascent Solar Technologies Inc of Thornton, CO, USA – which designs and makes lightweight, flexible copper indium gallium diselenide (CIGS) thin-film photovoltaic (PV) modules that can be integrated into consumer products, off-grid applications and aerospace applications – has announced a strategic partnership with Defiant Space Corp, an emerging space company focused on scalable solutions for the defense and national security market.
The firms will pursue opportunities in the US defense and national security sectors, combining Ascent’s space-proven solar technology with Defiant’s ability to develop and integrate mission-focused space solutions. The collaboration is designed to address the growing demand for resilient, cost-effective capabilities supporting defense and security objectives.
In addition, Ascent and Defiant will collaborate to explore opportunities across allied and international space markets, including NATO and Five Eyes partner nations. By combining Defiant’s strategic relationships with Ascent’s proprietary thin-film solar technology, the companies aim to identify areas where advanced US solar solutions can contribute to shared defense, security and commercial initiatives.
“Partnering with Defiant neatly aligns with Ascent’s mission to deliver lightweight, flexible and highly durable solar solutions to the most demanding markets,” says Ascent Solar’s CEO Paul Warley. “By combining our technology with Defiant’s platforms, we are strengthening our role in US national security initiatives and opening new commercial pathways for Ascent,” he adds.
“Defiant is focused on developing scalable solutions that strengthen the defense and national security market,” says Defiant Space’s chief strategy officer Jeromy Grimmett. “By working with Ascent Solar, we can advance innovative technologies that align with critical mission needs while also creating new opportunities abroad for US-developed space capabilities.”
The partnership reflects the growing importance of resilient, dual-use space technologies in both government and commercial domains. By aligning their capabilities, Ascent and Defiant reckon that they are well positioned to serve the rapidly expanding $1 trillion global space economy projected by 2040.
