Space Photovoltaics

The greatest share of Spectrolab's product deliveries are fully assembled space solar panels. Based on a customer's specifications for maximum area, operating temperature and voltage, and the mission environment and duration, Spectrolab engineers maximize performance for End of Life performance. The panel substrates onto which Spectrolab's multijunction circuits are bonded and wired to terminations, are provided as customer-furnished equipment.

Spectrolab offers a range of GaInP/GaAs/Ge lattice matched 3J solar cells with efficiencies reaching 32%. All 3J technologies are fully AIAA S111 and S112 qualified. Spectrolab's space solar cells can be purchased as bare cells or assemblies complete with space-qualified coverglass, bypass diode, and interconnects for welded connections between solar cells (CICs).
