Flexible power for the space age
Launch small. Deploy power at scale.
Heliofold is developing ultra-thin HJT photovoltaic cells and an SCPI roll-to-roll solar blanket designed for compact stowage and large-area deployment in orbit.
Primary technology routes
Flexible photovoltaic building blocks for orbital power.
The current portfolio centers on a flexible P-type HJT cell platform and a future solar blanket architecture that combines compact deployment with lightweight protective materials.
SCPI Solar Blanket
A deployable photovoltaic surface built to roll into a compact volume for launch and unfold into a large power-generating area in orbit.

Thin, flexible, and built for stack-level evaluation.
The Heliofold P-type HJT platform uses a 65 µm silicon cell in a symmetric flexible module concept. It gives integrators a physical starting point for bend mechanics, interconnect design, protection-layer selection, and lightweight array trade studies.

SCPI Solar Blanket
A compact answer to the stowage problem.
Rigid solar panels consume valuable fairing volume. Heliofold's solar blanket concept uses an ultra-thin flexible substrate, high-efficiency HJT cells, and a transparent SCPI protection layer to create a surface that can roll for launch and deploy at full scale.
01
Compact stowageRoll-to-roll construction reduces packaged volume relative to rigid panel architectures.
02
Large deployed areaThe blanket unrolls into a full-size photovoltaic surface once on orbit.
03
Integrated material stackFlexible HJT and SCPI routes are developed as elements of one deployable power system.
