Solar cells are manufactured at our facility in Milan and can be provided either bare or
SCA (aka CIC) to serve the civil application markets with the best cost versus quality mix.
CESI is particularly proud of its distinctive positioning based on our attention and capability
to shape and fine tune our solar cells for the specific needs and applications of our customers.
Our standard triple junction space cells are state of the art 30% typical efficiency,
qualified for both LEO and GEO missions according to ECSS-E-ST20-08C standard. In
our continuous improvement effort, we are already investing with effective results into
four-junction cells towards space efficiencies beyond 35%.
