FIRST THIN FILM FESTIVAL

摘要

The constant evolution of the satellite market is askingfor better technical performances and reliability for areduced cost. Solar array is in front line of thischallenge.This can be achieved by present technologiesprogressive improvement in cost reduction or bytechnological breakthrough.To reach an effective End Of Live performance100W/kg of solar array is not so easy, even if you supposethat the mass of everything is nothing!Thin film cells are potential candidate to contribute tothis challenge with certain confidence level andconsequent development plan validation andqualification on ground and flight.Based on a strong flight heritage in flexible SolarArray design, the work has allowed in these last years,to pave the way on road map of thin film technologies .This is encouraged by ESA on many technologicalcontracts put in concurrent engineering.CISG was selected cell and their strategy of design,contributions and results will be presented.Trade-off results and Design to Cost solutions willdiscussed.Main technical drivers, system design constraints,market access, key technologies needed will bedetailed in this paper and the resulting road-map anddevelopment plan will be presented.
