What are the advantages of triple junction gallium arsenide batteries?
Speaking of triple junction gallium arsenide batteries, I believe many users are familiar with them, especially for personnel in the field of space stations or large research institutes. So today, let's not discuss other issues, but mainly talk about the advantages of triple junction gallium arsenide batteries. Here are 7 advantages that the editor has compiled for everyone to take a look together!
Triple junction gallium arsenide batteries have the following advantages:
1. High photoelectric conversion efficiency: composed of three different materials of single junction diodes connected in series, usually including GaInP top cell, GaAs middle cell, and InGaAs bottom cell. Different layer materials have different band gaps, which can absorb photons in different bands of the solar spectrum, thereby more effectively converting light energy into electrical energy. Generally, it can reach over 30%, and even over 50% under laboratory conditions.
2. Strong radiation resistance: Gallium arsenide is a direct bandgap material, which has better resistance to high-energy particle irradiation compared to indirect bandgap materials such as silicon. It can maintain stable performance in strong radiation environments outside the Earth's atmosphere, ensuring power generation efficiency, and is suitable for use on spacecraft such as space stations and satellites.
3. Good high temperature resistance: With a wide bandgap, its open circuit voltage decreases slowly and efficiency decreases slowly in high temperature environments. It can continue to operate with a certain efficiency at 200 ℃, while silicon solar cells may have stopped working at this time.
4. High light absorption coefficient: As a direct bandgap material, the light absorption coefficient is high, and the active region only needs 3-5 microns to absorb the strongest part of the solar spectrum. In contrast, silicon materials require a thickness of hundreds of microns to fully absorb sunlight.
5. Lightweight and compact: It can be made into a thin film structure, with light weight and small size. In aerospace and other fields that require strict weight and space requirements, it can effectively reduce the load weight of spacecraft and has significant advantages.
6. Wide spectral absorption range: The absorption spectral range can reach 1800 nanometers or even wider, which is wider than the absorption spectral range of crystalline silicon solar cells and can absorb and utilize more sunlight.
7. Good Stability 2: The product performance and stability have reached world-class levels, such as the triple junction gallium arsenide solar cell of dry photovoltaics, which has been mass-produced and shipped for more than 10 years. Its stability and radiation resistance in space are significantly better than silicon-based cells, and its lifespan can reach 10 to 15 years.
Overall, triple junction gallium arsenide batteries have the above 7 advantages, including but not limited to high photoelectric conversion efficiency, strong radiation resistance, good high-temperature resistance, high light absorption coefficient, lightweight and small size, wide spectral absorption range, and good stability. Other advantages are also welcome to be added.
