New design of SA based on single and multi-junction GaAs/Ge SC intended for long-term operation on spacecrafts

We report new design of solar panels with application of single and multi-junction solar cells (SC) based on GaAs/Ge, GaInP/GaAs/Ge located on mesh semi-rigid frames. Earlier the similar frames were used in development of many types of SA based on mono-Si for Russian spacecrafts. Their application in case of highly effective SC based on GaAs/Ge, GaInP-GaAs/Ge is considered for the first time and is connected with the necessity to reach optimum energy-mass characteristics, to provide the best temperature modes during spacecraft operation. The obtained results testify on potential of application of considered type of solar panels on spacecraft.
