Ascent Solar Expands Thin-Film Technology Testing in Extreme Ocean and Space Environments

Ascent Solar Technologies Inc. has delivered test samples to two customers to evaluate its thin-film photovoltaic technology in extreme environments, marking a significant expansion of solar power applications beyond terrestrial uses. The Thornton, Colorado-based company, which previously demonstrated its technology in space applications, is now pushing into ocean monitoring and advanced space power systems.

The first customer, an ocean monitoring technology company developing autonomous underwater vehicles, will test Ascent's solar technology for functionality and durability in aquatic terrestrial applications. This testing aims to enable persistent operation of ocean-based monitoring technologies that require high speed, endurance, and sensing capabilities across diverse marine environments.

The second customer, a manufacturer of cutting-edge power lasers for space and defense industries, will evaluate Ascent's photovoltaic modules for space-based power beaming receiving capabilities. This technology could enable power transmission between satellites in orbit, representing a potential breakthrough for space infrastructure and operations.

"We see underwater and space applications as unique opportunities for thin-film PV to thrive, as the technology's lightweight, flexible and durable design allows it to withstand the immense pressures and tempestuous conditions that define these environments," said Paul Warley, CEO of Ascent Solar Technologies. The company anticipates reviewing test findings to unlock thin-film solar technology's potential in both emerging markets.

Ascent's CIGS thin-film photovoltaic products distinguish themselves through several key advantages: they are lightweight, flexible, bendable, perform well in low-light conditions and extreme temperatures, and offer greater durability than conventional solar solutions. Manufacturing at its Thornton, Colorado facility, the company can deliver solar arrays in six to eight weeks, significantly faster than competitors' nine to twelve month lead times.

The market potential for these applications is substantial. The marine environment solar market is forecast to grow from $1.2 billion to $3.5 billion by 2033, while the space industry represents a $6.8 billion opportunity for Ascent by 2040. This growth is driven by multiple factors: the need for environmentally-friendly power solutions for exploration vessels and equipment, new regulations pushing carbon footprint reduction, and advances in solar panel efficiencies making the technology more viable across industries.

Ascent has already demonstrated success in space applications through partnerships with NASA. The NASA Marshall Space Flight Center, with support from NASA Glenn Research Center, collaborated with Ascent to develop a space-based power system using CIGS PV modules to receive beamed power. This supports NASA's mission to enhance space capabilities while reducing costs. Additionally, Ascent's summer agreement with NOVI Space Inc. involves providing rollable PV array blankets for AI-powered satellites delivering real-time Earth Observation insights.

These developments come as global demand increases for reliable, cost-effective solar solutions that can operate in challenging conditions. Solar power has proven both reliable and cost-effective across multiple applications, and Ascent's expansion into extreme environments represents the next frontier for renewable energy technology. The company's ability to withstand harsh conditions while maintaining performance could revolutionize how we power equipment in the most inaccessible parts of our world and beyond.

The current test deliveries to ocean monitoring and space power customers mark a strategic milestone in Ascent's plan to replicate its space success in maritime and defense industries. As solar technology continues advancing, its role in exploration and communications—from outer space to the Pacific Ocean—expands, with thin-film photovoltaics leading the charge into previously inaccessible environments.
