Abstract :
GaAs/Ge (inactive germanium) solar cells (8 cm2) grown on a 0.2 mm thick Ge substrates has been space qualified and produced in a large-scale production environment (>2000 8 cm2 cells/week). AMO efficiencies over 20% have been demonstrated for areas up to 6 cm×6 cm, A detailed discussion is given on MOCVD technology improvements made in high throughput GaAs solar cell manufacture. Results showing the consistency of layer composition and quality on several different cell structures are presented
