CESI is particularly proud of its distinctive positioning based on its attention and capability to shape and fine tune solar cells for the specific needs and applications of any mission of its customers.

The CESI standard triple junction space cells have state of the art 30% typical efficiency, qualified for LEO and GEO missions according to ECSS-E-ST20-08C standard. In its continuous improvement effort, CESI is already investing with effective results on four-junction cells towards space efficiencies beyond 35%.
