  • Abstract
    A monolithically grown two-junction solar cell has been fabricated which produces 23.9% efficiency under AM1.5 global conditions and 22.3% under AM0 conditions. These are the highest one-sun efficiencies reported to date for both AM0 and AM1.5. The Al.35Ga.65As (1.93 eV) top cell and the GaAs (1.42 eV) bottom cell were grown by metal-organic chemical vapor deposition on GaAs substrates. Cell design and processing are described, and results of cell testing are presented.
