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 9):
The four junction solar cell assembly as defined in  claim 1 , further comprising a tunnel diode disposed over the fourth subcell, and intermediate layer disposed between the third subcell and the tunnel diode wherein the intermediate layer is compositionally graded to lattice match the third solar subcell on one side and the tunnel diode on the other side and is composed of any of the As, P, N, Sb based III-V compound semiconductors subject to the constraints of having the in-plane lattice parameter greater than or equal to that of the third solar subcell and different than that of the tunnel diode, and having a band gap energy greater than that of the fourth solar subcell.
