We address the challenge in depositing ultra-thin GaAs cells (<200 nm) using a more scalable process (metal-organic chemical vapor deposition). We present results for a GaAs/GaAs double-junction solar cell with a 110-nm-thick top cell. Current, voltage, fill factor, and efficiency of this archite...
