Zusammenfassung:A multijunction solar cell including an upper first solar subcell having a first band gap and positioned for receiving an incoming light beam; a second solar subcell disposed below and adjacent to and lattice matched with said upper first solar subcell, and having a second band gap smaller than said first band gap; wherein a layer of light scattering elements is provided below and adjacent to the bottom solar subcell for redirecting the incoming light to be totally internally reflected within the solar cell.
