Abstract: A multijunction solar cell including an upper first solar subcell having a first band gap; a second solar subcell adjacent to the first solar subcell and having a second band gap smaller than the first band gap; a graded interlayer adjacent to the second solar subcell, the first graded interlayer having a third band gap greater than the second band gap; and a third solar subcell adjacent to the graded interlayer, the third subcell having a fourth band gap smaller than the second band gap such that the third subcell is lattice mismatched with respect to the second subcell. A lower fourth solar subcell is provided adjacent to the third subcell and lattice matched thereto, the lower fourth subcell having a fifth band gap smaller than the fourth band gap.
