Flexell Space Secures $20 Million for Space Solar Tech

Flexell Space, a pioneer in next-generation space solar solutions, has announced the successful completion of a $20 million Series A funding round. This substantial investment, achieved approximately two years after the company's inception, highlights strong backing from prominent South Korean investors.

The company specializes in developing high-efficiency, ultra-lightweight, and flexible solar cells based on perovskite and copper indium gallium selenide (CIGS) technologies. These advanced solar cells offer significant advantages over conventional gallium arsenide cells, including lower weight, greater scalability, and improved cost-effectiveness, making them ideal for a range of space applications.

Existing investors like InterVest and L&S Venture Capital participated in this round, alongside new investors such as Mirae Asset Venture Investment and the Industrial Bank of Korea. Including a prior $4 million Pre-Series A round, Flexell Space has now secured approximately $25 million in cumulative funding.

Currently, Flexell Space is actively engaged in in-orbit demonstrations through South Korea's Nuri launch vehicle program and the International Space Station. The company is also undertaking rigorous testing, including radiation and thermal-vacuum tests, while forging partnerships with global defense contractors and satellite manufacturers.

Further bolstering its financial foundation, Flexell Space was recently chosen to lead a major national R&D project funded by the Korean government, totaling approximately US$7.1 million over five years. This project will focus on developing low-cost, high-efficiency tandem solar modules for space.

The newly acquired capital will be instrumental in upgrading pilot manufacturing facilities, acquiring essential equipment, scaling production processes, and expanding sample deliveries. Flexell Space aims to evolve into an integrated space energy solutions provider.

According to Keosan Lee, CFO of Flexell Space, this funding signifies the company's readiness for commercialization and production. "We can advance technology development, space-environment validation, and manufacturing infrastructure in parallel," Lee stated.

Flexell Space anticipates that demand for lightweight, cost-competitive power systems will surge with the expansion of low-Earth-orbit communications networks and increased power requirements for satellites and orbital data centers. The company plans to commence full-scale production by 2028 and expand its offerings globally.
