Abstract (en)
[origin: WO2018134016A1] The present invention relates to multiple solar cells comprising at least four pn junctions comprising a light-remote rear-side germanium subcell (1) and, arranged above the germanium subcell, at least three subcells (2, 2', 2'', 2''',...) composed of III-V compound semiconductors, wherein the multiple solar cells comprise at least one metamorphic buffer layer (3) and at least one wafer bond connection (4), and all layers arranged above the germanium subcell each contain a light-absorbing emitter and/or base layer containing at least 20% indium, relative to the sum of all group III atoms. Furthermore, the present invention relates to the use of said multiple solar cells in space.
