    摘要: Methods of fabricating solar cell emitter regions with differentiated P-type and N-type regions architectures, and resulting solar cells, are described. In an example, a back contact solar cell can include a substrate having a light-receiving surface and a back surface. A first polycrystalline silicon emitter region of a first conductivity type is disposed on a first thin dielectric layer disposed on the back surface of the substrate. A second polycrystalline silicon emitter region of a second, different, conductivity type is disposed on a second thin dielectric layer disposed on the back surface of the substrate. A third thin dielectric layer is disposed over an exposed outer portion of the first polycrystalline silicon emitter region and is disposed laterally directly between the first and second polycrystalline silicon emitter regions. A first conductive contact structure is disposed on the first polycrystalline silicon emitter region. A second conductive contact structure is disposed on the second polycrystalline silicon emitter region. Metallization methods, include etching techniques for forming a first and second conductive contact structure are also described.

    摘要: A method of fabricating a solar cell can include forming a first dopant region over a silicon substrate and an oxide region over the first dopant region. In an embodiment, the oxide region can protect the first dopant region from a first etching process. In an embodiment, a second dopant region can be formed over the silicon substrate, where a mask can be formed to protect a first portion of the second dopant region from the first etching process. In an embodiment, the first etching process can be performed to expose portions of the silicon substrate and/or a silicon region. A second etching process can be performed to form a trench region to separate a first and second doped region of the solar cell. A third etching process can be performed to remove contaminants from the solar cell and remove any remaining portions of the oxide region.

    摘要: Approaches for the metallization of solar cells and the resulting solar cells are described. In an example, a method of fabricating a solar cell involves forming a plurality of alternating N-type and P-type regions in or above a substrate. The method also involves forming a metal seed layer on the plurality of alternating N-type and P-type regions. The method also involves patterning at least a portion of the metal seed layer at regions in alignment with locations between the alternating N-type and P-type regions. The method also involves, subsequent to the patterning, etching to form trenches at the locations between the alternating N-type and P-type regions, isolating the alternating N-type and P-type regions from one another.

    摘要: An intervertebral implant for insertion between adjacent vertebral bodies is provided. The intervertebral implant can include a first component. The first component can have a first articulating surface, which can be generally convex. The intervertebral implant can include a second component, which can be generally in the shape of a toroid. The second component can have a second articulating surface. The second articulating surface can be generally concave and articulable with the first articulating surface for retaining motion between the first and second vertebra. The second articulating surface can have a larger radius of curvature than the first articulating surface such that a portion of the first articulating surface extends into an aperture defined by the generally toroid shape.
