A long duration test is in progress for comparing various methods of attaching interconnects to solar cells for near-earth-orbit spacecraft. This JPL- and NASA-sponsored project has been cycling modules at between -80 Cel and +80 Cel since June 1983. As of April 1984, 29.000 cycles have been completed, and the cycling is continuing. Modules include examples of parallel gap and ultrasonic welding and of soldering as fabricated by the Space and Communications Group, Hughes Aircraft Company and by Spectrolab. Evaluation of module integrity has been made at periodic intervals. No measurable degradation has been detected to date.
