Cells and CICs

Spectrolab offers a range of Ga,InP/GaAs/Ge multijunction solar cells with efficiencies reaching 31%.

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”.  

 

 

Panels

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.

 

 

Arrays

Spectrolab provides solar panels for commercial, science, and military program solar arrays,

for integration onto spacecraft by satellite prime contractors.
