Key highlights
O.C.E. Technology (OCE) offers a GaInP2/GaAs/Ge on Ge substrate, triple junction solar cell assembly, equipped with an external Si bypass diode, interconnectors and cover glass. The solar cell is characterized by high efficiency and strong anti-radiation capacity.
OCE offers a range of satellite subsystems. These subsystems have been designed by Chinese space organisations over the past 20 years and have heritage on many Chinese satellites and space vehicles.
