Terrestrial crystalline silicon solar cells have become comparable to space solar cells with respect to power output and weight but can be manufactured at lower costs and with higher production rates. Therefore, modifications of terrestrial Siemens silicon solar cells were developed and subjected to all main tests mandatory for space qualification. The tests were performed, following the generic specification for space cells, ESA PSS-01-604, and include, among others, irradiation with 1 MeV electrons up to the extended electron fluence of 3EI6 e/cm2, thermal cycling from -175 to +95 deg C, coverglass bonding, thermo-optical properties, humidity and temperature, contact welding and cell interconnection with related stress tests as well as cell performance measurements after each test step. All tests were successfully passed and by this the modified terrestrial Siemens silicon solar cells are verified to be suitable for space application.
