Abstract:
1. A method of creating a solar cell, the method comprising: forming a substrate layer; growing a plurality of nanowires grown outwardly from the substrate layer, at least two of the nanowires including one or more sub-cells, each sub-cell being formed of a material having a bandgap voltage; forming first and second light guiding layers formed of a transparent, light scattering material on top of the substrate layer, the first and second light guiding layers each having the plurality of nanowires passing through them, the first and second light guiding layers configured to scatter light of a particular wavelength, the first light guiding layer directly contacting the substrate and the second light guiding layer being disposed further from the substrate layer than the first light guiding layer; forming a first light diffracting layer between a first light guiding layer and the second light guiding layer; and forming a second light diffracting layer between the second light guiding layer and a third light guiding layer that is further from the substrate layer than the second light guiding layer.
