TRIPLE-JUNCTION GAAS SOLAR CELL 3GA-3-30%
This cell type is an GaInP2/GaAs/Ge on Ge substrate triple junction solar cell assembly (efficiency class 30-32%) The solar cell assembly is equipped with an discrete Si bypass diode, interconnectors and cover glass.
Our standard triple junction space cells (InGaP/InGaAs/Ge) are state of the art with a typical efficiency of 30-32%. They are qualified for both Low Earth Orbit (LEO) and Geostationary Orbit (GEO) satellites according to standard ECSS E ST20-08C (see datasheet SC-3GA-3 below). We continuously seek to make our cells more efficient and our research suggests we will be able to produce four junction cells with space efficiencies beyond 36%.Used for space solar system projects and space solar power systems, space grade solar cells, and excellent space engineers solar panels.

Solar Cell Schematic or Circuit Diagram
Our solar cell is produced under european standard ECSS.
Space Assemblies are space solutions with a higher integration level. Based on our high-efficiency solar cells of the 28% or 32%-Advanced class, the assemblies are additionally equipped with cover glasses and interconnectors.
The cell dimensions as well as the integrated bypass diode are the same as for the bare solar cells. The cover glass covers the whole area of cell and is fixed by bonding with a transparent adhesive onto the front side of the solar cell. The interconnectors are covered with silver, fixed by a sophisticated welding process and designed for LEO, MEO and GEO Missions. All used materials and components are space-qualified. In addition to our standard Solar Cell Assemblies, YIM SPACE offers various possibilities of customized solutions on individual requirements.
