Ascent Solar Technologies (Nasdaq: ASTI), a pioneering force in the development and production of lightweight, flexible, and durable CIGS thin-film photovoltaic (PV) solutions in the U.S., has announced the successful delivery of its latest, higher efficiency material for further evaluation.
This milestone marks the commencement of an extensive series of rigorous lifecycle tests aimed at emulating prolonged operational conditions in space. The trials are designed to guide Ascent’s pursuit of greater efficiencies and advancements. Notably, the company’s Plug & FlyTM arrays have gained traction among customers due to their ability to deliver equivalent power with significantly reduced mass and volume compared to alternatives. Recent efficiency breakthroughs further enhance these weight and volumetric efficiencies, potentially enabling spacecraft to operate with reduced dead weight and the potential for downsizing launch rideshare slots.
The ongoing tests, currently in the manufacturing phase, will precisely determine the required solar array area to generate end-of-life (EOL) power for individual space missions. This initiative not only aims to optimize product resilience but also extends product longevity in the demanding space environment.
Paul Warley, CEO of Ascent Solar Technologies, highlighted the robustness of their CIGS PV technology demonstrated during NASA’s MISSE-X experiment aboard the ISS. He emphasized the forthcoming long-duration simulated tests aimed at quantifying Ascent’s product degradation rate across the most demanding, decades-spanning space missions. The objective is to validate the cost and weight-saving benefits of Ascent’s solutions for current missions while paving the way for future spacecraft capabilities.
Spacecraft face considerable challenges in the harsh, degrading environment of space orbits, necessitating robust power generation capabilities over mission durations. Ascent’s testing program aims to not only reduce spacecraft mass budgets but also ensure adequate power margins for missions, even in deep space scenarios. This advancement could significantly impact hosted payload providers, extending revenue generation opportunities, and empower future spacecraft engineers to plan for sustained power supply over multiple customer payload life-cycles.
The potential for Ascent’s solar modules to reliably generate power for extended periods in orbit may open doors for futuristic business models previously deemed as science fiction, such as Lunar power stations or Dyson Spheres. Ascent Solar Technologies’ extensive testing program signifies a pivotal step toward transforming the landscape of space-based power solutions. |
