Setting New Standards for Space Power
We introduce the GaInP/GaAs/Ge High-Efficiency Space Solar Cell. This is a cutting-edge product designed for space missions. Its photoelectric conversion efficiency reaches 30%. This far exceeds traditional silicon-based solar cells. This cell is an ideal choice for GEO and LEO satellites.
Triple-Junction Technology and Structure
This cell uses an advanced triple-junction stacked design. It integrates three materials: GaInP, GaAs, and Ge. Each material layer has a unique bandgap.
Layer 1: GaInP (Gallium Indium Phosphide)
The GaInP layer is on top of the cell. It effectively absorbs high-energy, short-wavelength light. It mainly captures blue and violet light. This layer ensures high efficiency and stability in space.
Layer 2: GaAs (Gallium Arsenide)
The GaAs layer is the middle junction of the cell. It is responsible for absorbing medium-wavelength light. This includes the green to red spectrum. GaAs material has excellent resistance to radiation.
Layer 3: Ge (Germanium)
The Germanium (Ge) layer is at the bottom of the cell. It absorbs low-energy infrared light. It ensures the cell uses the complete solar spectrum. Germanium material offers high durability and radiation resistance.
Core Advantages and Performance
The triple-junction design doubles energy output. The cell uses lattice-matching technology. This ensures structural integrity between the different material layers. We apply a special anti-reflection coating. This minimizes light loss maximally. The cell also features high-quality electrical contacts. These designs ensure efficient energy collection and transfer.
Reliability in the Space Environment
This cell is designed for harsh space environments. It has very high resistance to space radiation. It is highly suitable for long-term operating missions. The cell’s service life extends up to 15 years. Its performance degradation is less than 18% over 15 years. This provides continuous and reliable power for spacecraft.
Flexible Customization Service
We offer a variety of customized specifications. Epitaxial wafer sizes are available in 4-inch and 6-inch. Chip sizes include 40mm x 60mm and 40mm x 80mm. These options meet the special needs of different aerospace missions. This product is a reliable energy solution for satellites, spacecraft, and space stations. Choosing it means choosing the success and longevity of your space mission.
