Abstract: A multijunction solar cell including a first solar subcell having a first band gap; a second solar subcell disposed over the first subcell and having a second band gap smaller than the first band gap; a grading interlayer disposed over the second subcell and having a third band gap greater than the second band gap; a third solar subcell disposed over the interlayer that is lattice mismatched with respect to the middle subcell and having a fourth band gap smaller than the second band gap; and either a thin (approximately 2-6 mil) substrate and/or a rigid coverglass supporting the first, second, and third solar subcells.
