Spectrolab offers a range of Ga,InP/GaAs/Ge multijunction solar cells with efficiencies reaching 30%.
Spectrolab’s space solar cells can be purchased as assemblies complete with space-qualified coverglass
to protect against cosmic radiation, a discrete silicon bypass diode to protect against shadow-induced
reverse bias, and interconnects for welded or soldered connections between
solar cells to create voltage-adding series “strings”.
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 provides solar panels for commercial, science, and military program solar arrays,
for integration onto spacecraft by satellite prime contractors.
