In the unforgiving environment of space, every watt counts. Whether your satellite is orbiting 400 kilometers above Earth in Low Earth Orbit (LEO) or stationed 35,786 kilometers away in Geostationary Orbit (GEO), reliable power is the lifeline of your mission.
That's where the Space TJ Triple-Junction Solar Cell comes in.
Built on cutting-edge GaInP₂/GaAs/Ge triple-junction epitaxy technology, the Space TJ delivers an exceptional 30–32% conversion efficiency—pushing the boundaries of what's possible in space photovoltaic technology.
Each cell arrives fully integrated with:
Si bypass diode for fault protection
Interconnectors for seamless array assembly
Cover glass for radiation shielding
Ready to install. Ready to perform.
Space TJ cells are rigorously tested and qualified for both LEO and GEO missions, meeting the stringent requirements of ECSS E ST20-08C—the gold standard for European space programs.
| Orbit | Altitude | Typical Missions |
|---|---|---|
| LEO | 200–2,000 km | Earth observation, communication constellations, scientific research |
| GEO | 35,786 km | Telecommunications, weather monitoring, broadcast services |
One product. Infinite possibilities.
Higher Efficiency
30–32% conversion efficiency means more power per square meter—critical when every gram of launch mass costs a fortune.
⚡ Faster Integration
Pre-integrated components eliminate post-assembly steps, reducing satellite production timelines and labor costs.
️ Proven Reliability
ECSS E ST20-08C qualification ensures your mission meets the highest industry standards.
Global Coverage
Dual-orbit qualification gives you the flexibility to serve diverse mission profiles with a single product line.
The triple-junction design captures sunlight across three distinct wavelength bands:
GaInP₂ top cell: Short wavelengths (300–680 nm)
GaAs middle cell: Medium wavelengths (680–900 nm)
Ge bottom cell: Long wavelengths (900–1,800 nm)
This multi-layer approach extracts up to 40% more energy than traditional single-junction silicon cells—essential for missions where sunlight is the only power source.
Space TJ cells power the missions that matter:
Commercial communications satellites
Government and defense payloads
Scientific and Earth observation platforms
Navigation and positioning systems
Emerging space tourism and manufacturing ventures
When you choose Space TJ, you're not just buying solar cells—you're investing in:
✅ Decades of space-proven heritage
✅ Rigorous quality control and traceability
✅ Dedicated technical support
✅ Flexible customization options
