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 5):
The four junction solar cell assembly as defined in  claim 1 , further comprising:\n a distributed Bragg reflector (DBR) layer adjacent to and disposed between the third and the fourth solar subcells and arranged so that light can enter and pass through the third solar subcell and at least a portion of which can be reflected back into the third solar subcell by the DBR layer, and is composed of a plurality of alternating sublayers of lattice matched materials with discontinuities in their respective indices of refraction; and wherein the difference in refractive indices between alternating sublayers is maximized in order to minimize the number of periods required to achieve a given reflectivity, and the thickness and refractive index of each period determines the stop band and its limiting wavelength.
