Flexell Space and Satoro Team Up for Space Solar Cell Tests

Flexell Space, under the leadership of CEO Taehun Ahn, has joined forces with Satoro, a Singapore-based CubeSat manufacturer led by CEO Mark Lu. Their collaborative effort focuses on the in-orbit demonstration and validation of advanced space solar cell technologies.

Planned Demonstrations

As part of this partnership, the companies will conduct two missions aboard SpaceX's Falcon 9 rockets, slated for launch in 2027 and 2028. The aim is to meticulously assess the performance and simplicity of Flexell Space’s solar cells in a real-world space setting.

Enhancing Solar Cell Validation

Previously, Flexell Space has executed successful demonstration missions via Korea's KSLV-II in late 2025 and into 2026. This new collaboration expands Flexell's capability to validate their innovative space solar cells and further collect operational data essential for commercial viability.

In this agreement, Satoro will take charge of satellite manufacturing for the demonstration missions, while Flexell will provide the solar cells and related test modules for integration. Together, they will align on the technical specifications needed for the CubeSat platforms and their demonstration payloads. This coordination will aid in evaluating solar cells’ functionality in orbit.

Comparative Analysis of Data

One of the critical goals for Flexell is to compare bench-tested outcomes with real-time in-orbit performance. They aim to gauge power output characteristics and performance variations over time. The insights gained from both missions will contribute to refining designs and enhancing reliability, establishing a robust technical basis that may attract future commercial clients.

A Collaborative Vision for the Future

This partnership effectively merges Satoro's expertise in CubeSat fabrication with Flexell's advanced solar cell technology development. Flexell focuses on creating solar cells employing copper indium gallium selenide (CIGS) and perovskite materials, emphasizing the establishment of affordable, lightweight power solutions for satellites and diverse space applications.

"To bring space solar cells to market, we need both ground and in-orbit validation of performance," stated Taehun Ahn, CEO of Flexell Space. "With two mission opportunities secured for 2027 and 2028, we are committed to validating the reliability of our next-generation solar cells and gathering the necessary technical evidence for global customers."

Ahn also noted that the collaboration with Satoro clears a path from development to in-orbit demonstration, facilitating quicker preparations for future supply.

Looking Forward

Mark Lu, CEO of Satoro, expressed enthusiasm about the collaboration stating, "We are excited to partner with Flexell Space in demonstrating its next-generation solar cells. Utilizing Satoro's CubeSat infrastructure and mission integration skills, we will secure the vital in-orbit data necessary for technology validation."

With the anticipation of these two important missions, both companies are optimistic about advancing new space power technologies and establishing a foundation for ongoing technical collaborations.
