Product Foundation

Product Features & Process Capability

Centered on flexible structures and controlled manufacturing, our flexible PV product system is scalable, testable, and adaptable to mission requirements

Foldable solar array hardware and deployment structure

Product Features

Ultra-Light and Thin: Built on flexible glass substrates, this architecture reduces overall thickness and mass relative to conventional glass-based PV modules, enabling conformal integration onto curved surfaces and compatibility with mass-constrained spacecraft platforms.

Bendable and Rollable: The cell and module architecture supports bending, folding, and rolling while maintaining structural integrity and stable performance.

Process Advantages

Mature and Stable Process: The fabrication flow is well established, with precise process control and strong batch-to-batch consistency.

Excellent Film Quality: The photoactive layers are uniform and dense, with high crystallinity and low defect density for long-term stable operation.

Repeatability and Yield: A mature process framework ensures consistent batch performance and provides a foundation for reliability and long service life.

SPACE-GRADE COLORLESS POLYIMIDE (CPI) Film

Our space-grade CPI film is developed as a protective film system for space applications. It targets end-of-life (EOL) performance retention under long-duration LEO exposure. A UV-blocking protective layer helps preserve long-term film integrity while maintaining high optical transmittance. The material system is developed for resistance to atomic oxygen erosion, thermal cycling, and low outgassing in spaceflight environments.
