Solar cells for space applications
Project data
Client Challenge
Space solar arrays need more and more efficient and reliable solar cells. Since 2000 the devices based on GaAs compounds have overcome silicon solar cells in the space sector thanks to the higher performances and resistance against the harsh space environment.
Since 2005 about 25 different satellites were powered by these solar cells.
What we've done
CESI is one of the few industrial suppliers of GaAs based solar cells, worldwide.
Since the first GaAs solar cells that flew in space in 1984 on board of an ESA calibration experiment, CESI solar cells powered more than 60 satellites of 19 different Countries experiencing 100% success (no failures).
Now CESI is producing fully qualified (ESA ECSS-E20-08) high efficiency triple junction InGaP/InGaAs/Ge solar cells using its proprietary structure.
Since 2005 about 25 different satellites were powered by these solar cells.
Client benefits
CESI has a worldwide recognized experience in III-V solar cells and can offer devices characterized by excellent performances and proved reliability. CESI is supporting the client and it is flexible in collaboration and product customization to reach 100% customer satisfaction.
