R&D on III-V Compound Solar Cells for Space Application at TIPS

Driven by the market needs from high capacity telecommunication satellites, Tianjin Institute of Power Sources has made intensive efforts to develop GaAs based III-V compound solar cells in the last decade. A 20 KW/year production line was soon established and solar panels with GaAs/Ge single junction solar cells of excellent performance have been delivered for several telecommunication satellite projects. Meanwhile, successful research work in recent years on GaInP/GaInAs/Ge multijunction solar cells has resulted TIPS's first generation of triplejunction product with average efficiency above 26.5%
