About
The Solar Element GaInP2/GaAs/Ge is a triple-junction semiconductor solar cell for use in solar power supply systems of spacecraft to convert solar energy into electrical energy. It offers 28.5% efficiency and can be delivered in standard 80 × 40 mm format in three thicknesses (0.09, 0.11, or 0.14 mm). The cell dimensions and contact system design can be modified on customer request (area from 4 mm² to 60.3 mm²). Released in 2007 with a 1-month delivery lead time and established flight heritage.
