6U satellite board trapezoidal GaAs solar panel
6U satellite board trapezoidal GaAs solar panel GaAs aviation grade GaAs solar cell module
product details
The band gap of GaAs solar cells is wider than that of silicon, which makes its spectral responsiveness and spatial spectral matching ability better than that of silicon. At present, the theoretical efficiency of silicon cells is about 23%, while the theoretical efficiency of single-junction GaAs solar cells is 27%, while the theoretical efficiency of multi-junction GaAs solar cells is more than 50%.
Three-junction GaAs solar cells have the advantages of high conversion efficiency, high reliability, high temperature resistance and strong irradiation resistance. The products have been widely used in remote sensing, meteorological and scientific experiments and other satellites.
Product characteristics:
Trapezoidal GaAs solar cells
Taking the 3V bus voltage as the baseline product
Other bus voltage mode can be customized.
