Abstract:
A solar cell comprising a bulk germanium silicon growth substrate; a diffused photoactive junction in the germanium silicon substrate; and a sequence of subcells grown over the substrate, with the first grown subcell either being lattice matched or lattice mis-matched to the growth substrate.

Claim (Index 14):
The four junction solar cell assembly as defined in  claim 1 , wherein each subcell includes an emitter region and a base region, and one or more of the subcells have a base region having a gradation in doping that increases exponentially from 1\u00d710 15  atoms per cubic centimeter adjacent the p-n junction to 4\u00d710 18  atoms per cubic centimeter adjacent to the adjoining layer at the rear of the base, and an emitter region having a gradation in doping that decreases from approximately 5\u00d710 18  atoms per cubic centimeter in the region immediately adjacent the adjoining layer to 5\u00d710 17  atoms per cubic centimeter in the region adjacent to the p-n junction.
