Electrical performance data (AM0,1SUN,1353w/㎡,25℃)

The triple-junction GaAs solar cell uses germanium as the substrate and consists of three N/P sub-cells connected in series through a tunnel junction. It is equipped with independent silicon diodes, interconnects, and glass covers. It has high efficiency and strong radiation resistance. Application areas: low-altitude aircraft, medium-orbit aircraft, high-altitude aircraft (nano-satellites, small satellites, commercial satellites, large satellites, drones, etc.)
