Abstract
A stacked, monolithic, upright metamorphic, terrestrial concentrator solar cell having exactly five subcells and having a metamorphic buffer, wherein a first subcell has a first lattice constant G1 and consists essentially of germanium, a second subcell has a second lattice constant and GaInAs, a third subcell has the second lattice constant G2 and AlGaInAs, a fourth subcell has the second lattice constant G2 and InP, a fifth subcell has the second lattice constant G2 and InP, G1<G2 applies to the lattice constants, the metamorphic buffer is arranged between the first subcell and the second subcell and has the first lattice constant G1 on a bottom side facing the first subcell and the second lattice constant G2 on a top side facing the second subcell, and all of the semiconductor layers of the concentrator solar cell arranged above the first subcell are epitaxially produced on the preceding subcell.
