Product Description: GaInP/GaAs/Ge High-Efficiency Space Solar Cell – Suitable for GEO/LEO Orbit Satellites
Our 30% efficiency GaInP/GaAs/Ge high-efficiency space solar cell is a leading-edge solution designed specifically for space applications. It integrates advanced triple-junction solar cell technology, featuring a unique combination of materials, including GaInP (Gallium Indium Phosphide), GaAs (Gallium Arsenide), and Ge (Germanium). These materials are chosen for their ability to absorb a broader spectrum of sunlight and maximize energy conversion, offering outstanding efficiency and performance in space.
Key Features:
High Efficiency (30%): Delivers 30% efficiency, much higher than conventional silicon solar cells, making it ideal for space missions.
Triple-Junction Design: The cell incorporates a GaInP/GaAs/Ge structure, where each layer has a specific bandgap that enables the absorption of different wavelengths of sunlight. This maximizes energy conversion, achieving double the energy output compared to traditional silicon-based solar cells.
Wide Application: Specifically designed for use in GEO (Geostationary Earth Orbit) and LEO (Low Earth Orbit) satellites, this solar cell is also suitable for other space applications, including spacecraft and space stations.
Radiation Resistance: The materials used in the cell, particularly GaAs, have high resistance to space radiation, making it highly durable in harsh space environments.
Long Lifespan: The solar cell has a 15-year service life, with less than 18% degradation, ensuring reliable performance for extended periods in space.
Customizable Specifications: Available in 4-inch and 6-inch epitaxial wafer sizes, with customizable chip sizes, including 40mm x 60mm and 40mm x 80mm, to meet specific mission requirements.
Battery Structure and Components:
GaInP Layer (Top Junction): This layer absorbs the high-energy portion of the solar spectrum, effectively capturing short-wavelength light (blue and violet). The GaInP material offers high efficiency and stability in space.
GaAs Layer (Middle Junction): The second junction, made of GaAs, absorbs medium-wavelength light (green to red) and provides excellent resistance to radiation. This layer plays a critical role in the overall efficiency of the cell.
Ge Layer (Bottom Junction): The Germanium (Ge) layer absorbs low-energy infrared light, ensuring that the solar cell makes use of the entire solar spectrum. Ge is particularly suited for the bottom junction due to its high tolerance to radiation and durability.
Lattice-Matching Technology: The layers are carefully designed to be lattice-matched, ensuring minimal dislocations between the different materials, which leads to better structural integrity and higher efficiency in energy conversion.
Anti-Reflection Coating: A special anti-reflection coating is applied to reduce light loss and enhance the cell’s efficiency by ensuring maximum light absorption.
Electrical Contacts: High-quality electrical contacts are used to ensure efficient energy collection and transfer from the solar cell to the spacecraft’s power systems. These contacts are designed to withstand the harsh space environment and radiation.
Encapsulation: The cell is encapsulated in a robust material that protects the structure from space debris, radiation, and other environmental factors. This encapsulation ensures longevity and reliable operation.
