  • Monolithic metamorphic multi-junction solar cell
    Patent number: 11588067
    Abstract: A monolithic multi-junction solar cell comprising a first III-V subcell and a second III-V subcell and a third III-V subcell and a fourth Ge subcell, wherein the subcells are stacked on top of one another in the specified order, and the first subcell forms the top subcell and a metamorphic buffer is formed between the third subcell and the fourth subcell and all subcells each have an n-doped emitter layer and a p-doped base layer and the emitter doping in the second subcell is lower than the base doping.
    Type: Grant
    Filed: July 12, 2021
    Date of Patent: February 21, 2023
    Assignee: AZUR SPACE Solar Power GmbH
