Abstract:
A four junction solar cell having an upper first solar subcell composed of a semiconductor material having a first band gap; a second solar subcell adjacent to said first solar subcell and composed of a semiconductor material having a second band gap smaller than the first band gap and being lattice matched with the upper first solar subcell; a third solar subcell adjacent to said second solar subcell and composed of a semiconductor material having a third band gap smaller than the second band gap and being lattice matched with the second solar subcell; and a fourth solar subcell adjacent to and lattice mismatched from said third solar subcell and composed of a semiconductor material having a fourth band gap smaller than the third band gap; wherein the fourth subcell has a direct bandgap of greater than 0.75 eV, and the average band gap of the solar cell is equal to or greater than 1.35 eV.

Claim (Index 10):
The four junction solar cell assembly as defined in  claim 1 , further comprising an intermediate layer disposed between the third subcell and the fourth subcell wherein the intermediate layer is compositionally step-graded with between one and four steps to lattice match the fourth solar subcell on one side and composed of In x Ga 1-x As or (In x Ga 1-x ) y Al 1-y As with 0<x<1, 0<y<1, and x and y selected such that the band gap is in the range of 1.15 to 1.41 eV throughout its thickness.
