GaAs Solar Arrays

Triple junction GaInP/GaInAs/Ge epitaxial structure solar cells Integrated cover glass for improved durability and radiation protection Integrated by-pass diode NASA qualified low outgassing solar cell adhesive; Internal copper ground planes for improved EMI compatibility; Circuit design without current loops to avoid spontaneous satellite spin up due to parasitic magnetic dipole effects; Multiple arrays can be connected in parallel or series (by-pass and blocking diodes are used to protect individual cells and modules from shading effects) PCB thickness: <1.7 mm Panel base material: FR-4 (IPC-6012B) IPC – A600H class 3 assembly, hand soldering per ESA specification ECSS-Q-70-08 Operational temperature: -40 °C to +85 °C

NanoAvionics GaAs solar arrays are made of high performance triple junction space grade solar cells that enable missions with high power requirements. These solar cells reach up to 28.7 % efficiency and have an integrated by-pass diode to protect in series connected solar cell string from shadowing effects. Solar cells are assembled using NASA qualified low outgassing adhesive materials in clean room environment. Upon request NanoAvionics is able to produce customized solar panels including deployables.
