摘要： A multijunction solar cell which includes: an upper first solar subcell having a first band gap; a second solar subcell adjacent to said upper first solar subcell and having a second band gap smaller than said first band gap; a third solar subcell adjacent to said second solar subcell and having a third band gap smaller than said second band gap; a graded interlayer adjacent to said third solar subcell, said graded interlayer having a fourth band gap greater than said third band gap; and a lower fourth solar subcell adjacent to said graded interlayer, said lower fourth solar subcell having a fifth band gap smaller than said third band gap such that said lower fourth solar subcell is lattice mismatched with respect to said third solar subcell.
