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.
The 3G30C-Advanced bare cell device is a space-qualified InGaP/GaAs/Ge triple-junction solar cell originating from a 150 mm germanium substrate and provides 30% class beginning-of-life (BOL) efficiency. The standard cell features well-proven metallization as well as an improved busbar and grid design with two contact pads plus one for a discrete bypass diode connection, and a standard bare cell size of 71.25 cm2 (6 cm x 12 cm). This configuration offers a bare cell total thickness of 150 micrometres. The cell is compatible with an external bypass diode, also available from AZUR SPACE together with bare cell orders.
The 3G30A assembly includes a 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, for an assembly total device thickness of 290 micrometres.
