WO/2015/094377 PHOTODETECTOR WITH TAPERED WAVEGUIDE STRUCTURE||WO||25.06.2015|
||PCT/US2013/077313||INTEL CORPORATION||VINCENT, Benjamin|
Techniques and mechanisms for providing efficient direction of light to a photodetector with a tapered waveguide structure. In an embodiment, a taper structure of a semiconductor device comprises a substantially single crystalline silicon. A buried oxide underlies and adjoins the monocrystalline silicon of the taper structure, and a polycrystalline Si is disposed under the buried oxide. During operation of the semiconductor device light is redirected in the taper structure and received via a first side of a Germanium photodetector. In another embodiment, one or more mirror structures positioned on a far side of the Germanium photodetector may provide for a portion of the light to be reflected back to the Germanium photodetector.

||PCT/US2014/071301||URIEL SOLAR, INC.||GARNETT, James, David|
The present disclosure provides thin film solar cell
structures that can achieve dramatically improved power conversion
efficiencies in relation to other thin film solar cell
structures. The application of tandem solar cells
composed of poly-crystalline Group II- VI (e.g., CdTe-based alloy) solar cells
under low temperature deposition can achieve practical efficiencies above 25% in a low cost, high through-put, large area production environment. A poly- crystalline Group II- VI (e.g., CdTe-based alloy) solar cell
can be deposited in tandem with a crystalline or multi-crystalline silicon p-type substrate with embedded n-type emitter on the deposition side of the substrate. This low temperature poly-crystalline/crystalline approach can allow for the development of a substantially efficient tandem solar cell
produced in a relatively low cost, high through-put, large area production environment.
