During the last couple of years the application of triple junction GaInP/GaInAs/Ge solar cells for all kind of missions - LEO, GEO, MEO and inter-planetary missions - came to pass, replacing the Si solar cells and related processing parameters. Comprehensive qualification programs have been performed at Astrium in order to qualify the new generations of solar cell types with Astrium's PVA technology. The actual generation of European triple junction GaInP/GaInAs/Ge solar cells manufactured by AZUR SPACE has been successfully qualified in the frame of the ESA ARTES3 programe for GEO-applications likeEurostar 3000 and Alpha-Bus and in the frame of GalileoSat for a MEO orbit. The delta qualification of the 3G28-ID2* solar cell and the associated PVA technology for LEO is currently running for the ESA SWARM project which will have operational temperatures up to 140 deg C in combination with an ATOX environment. The high operational temperature in combination with the high number of thermal cycles is a challenge for the solar cell interconnection technology and for the integral diode (ID2 *). Different solar cell interconnector technologies have to be used and a protection against the ATOX environment has to be implemented. A further challenge of the SWARM project is the requirement for extremely high magnetic cleanliness. This paper will present qualification test results and the technical solutions to overcome the outlined challenges on PVA level.
