Abstract :
5 μm thick GaAs solar cells and the corresponding module and solar array technology have been developed under support of DARA and EsteC. The main advantages of this technology are: high electrical conversion efficiency; potential improvements by multijunction systems; bifacial application in LEO applications; and submodule protection against reverse operation by integrated shunt diodes. The first application of the 5 μm GaAs technology is the German small satellite Equator-S. The satellite will be launched into a 500/63000 km orbit in 1997
