Abstract

To transcend triple-junction devices limits, we explores III-V quintuple-junction solar cells using a detailed balance model integrating graphical analysis and numerical traversal algorithm. We identified an ideal structure: (Al_0.438Ga_0.562)_0.51In_0.49P / Al_0.194Ga_0.806As / Ga_0.938In_0.062As / Ga_0.700In_0.300As / Ga_0.422In_0.578As (2.14/1.67/1.33/1.01/0.70 eV), yielding 57.47% efficiency. Transitioning to a practical GaInP/Ge architecture, it demonstrates exceptional process tolerance over GaSb alternatives, offering a wide processing window to guide next-generation photovoltaic fabrication.
