YIM offers a range of GaInP2/GaAs/Ge on Ge substrate triple junction solar cell assembly (efficiency class 30-32%) The solar cell assembly is equipped with an discrete Si bypass diode, interconnectors and cover glass.The interconnectors are covered with silver or kovar, fixed by a sophisticated welding process and designed for LEO, MEO and GEO Missions.All used materials and components are space-qualified.Complies with standard ECSS E ST20-08C.
Characteristics is high output power,high strong anti-radiation capacity,wide application range. Our triple junction GaAs solar cells in missions like Yaogan-32, Moziji, Haiyang-2B, Beidou-42, Piaochong-5, Chang’e-4,wangtong-1, Beidou-3（M12), Gaofen-11(02), ZY-3(03),NH-1,TT-5 and so on, also hundrends of international satellites missions, till now present very good performance. They are qualified for both Low Earth Orbit (LEO) and Geostationary Orbit (GEO) satellites according .
1.As a byproduct in the production of triple junction gallium arsenide solar cells, the efficiency is comparable to that of model solar cells, and the cost is much lower than that of model solar cells. The advantages of heterotypic solar cells are also reflected in flexible layout and the ability to output various bus voltages on small modules. 2: There are two specifications: triangular and trapezoidal. The packaging of triangular solar cells can only use commercial SMT, while trapezoidal solar cells can use SMT or universal resistance welding technology for space solar cells.
