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 6):
The four junction solar cell assembly as defined in  claim 5 , wherein the DBR layer includes a first DBR layer composed of a plurality of p type In z Al x Ga 1-x-z As sublayers, and a second DBR layer disposed over and adjacent to the first DBR layer and composed of a plurality of p type In w Al y Ga 1-y-w As sublayers, where 0<w<1, 0<x<1, 0<y<1, 0<z<1 and y is greater than x, thereby increasing the reflection bandwidth of the DBR layer.
