About
AZUR SPACE’s 3G30-Advanced bare solar cells and solar cell assemblies (SCA), or CICs (cell-interconnect-coverglass), are the ideal solution for space power applications in conventional or in New Space segments. The award-winning 3G30-Advanced technology design offers proven best-in-class end-of-life (EOL) performance at lowest cost-per-watt, enabling a multitude of heritage options for all orbits and missions.
The bare cell device is a space-qualified InGaP/GaAs/Ge triple-junction solar cell originating from a germanium substrate and provides 30% class beginning-of-life (BOL) efficiency. This device includes AZUR SPACE’s proprietary radiation-hardened design for best EOL performance.
The assembly includes the bare 3G30C-Advanced solar cell, a corner-mounted silicon bypass diode, welded in-plane silver-coated Kovar interconnectors and a 100 micrometre AR coated coverglass bonded with space-grade heritage adhesive.
The 3G30-Advanced technology, cells and assemblies are ECSS-E-ST-20-08C (Rev. 1) qualified. These devices are produced in the mature MRL-10 Heilbronn facility and have demonstrated on-orbit TRL-9 level heritage. Other non-standard sizes, thicknesses and configurations are available on request.
