Proton exposure
Resilience through the bulk
Engineered profiles support carrier collection as displacement damage accumulates within the silicon lattice.
Applications
Breakthrough wafer technology for flight.
EpiNex® enables breakthrough wafer and cell technology for Low Earth Orbit (LEO) satellites and High-Altitude Platforms (HAPS), where ultra-light, high-efficiency performance is essential.
The mission challenge
Every gram and every orbit count.
LEO platforms cycle through a demanding radiation environment while carrying strict mass and power budgets. A thinner, engineerable wafer creates new freedom at the foundation of the photovoltaic stack.
Drift-field design
Useful power over time
An internal field positioned away from the radiation-damaged zone helps preserve carrier collection over the mission.
Mission duration
Designed beyond day one
The material architecture supports power-system strategies aimed at longer operational life in LEO.
One platform. Mission-specific possibilities.
Direct epitaxial growth allows thickness and dopant profiles to be considered together, connecting wafer design to the specific power, mass and radiation needs of a spacecraft.
