    摘要： Approaches for the foil-based metallization of solar cells and the resulting solar cells are described. A method involves patterning a first surface of a metal foil to provide a plurality of alternating grooves and ridges in the metal foil. Non-conductive material regions are formed in the grooves in the metal foil. The metal foil is located above a plurality of alternating N-type and P-type semiconductor regions disposed in or above a substrate to provide the non-conductive material regions in alignment with locations between the alternating N-type and P-type semiconductor regions and to provide the ridges in alignment with the alternating N-type and P-type semiconductor regions. The ridges of the metal foil are adhered to the alternating N-type and P-type semiconductor regions. The metal foil is patterned through the metal foil from a second surface of the metal foil at regions in alignment with the non-conductive material regions.

    摘要： Methods of fabricating solar cell emitter regions with differentiated P-type and N-type region architectures, and resulting solar cells, are described. In an example a solar cell includes a first emitter region of a first conductivity type disposed on a first dielectric region, the first dielectric region disposed on a surface of a substrate. A second dielectric region is disposed laterally adjacent to the first and second emitter region. The second emitter region of a second, different, conductivity type is disposed on a third dielectric region, the third dielectric region disposed on the surface of the substrate, over the second dielectric region, and partially over the first emitter region. A first metal foil is disposed over the first emitter region. A second metal foil is disposed over the second emitter region.

    摘要： Methods of fabricating solar cell emitter regions with differentiated P-type and N-type architectures and incorporating dotted diffusion, and resulting solar cells, are described. In an example, a solar cell includes 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 in a plurality of non-continuous trenches in the back surface of the substrate.

    摘要： A system and method of patterning dopants of opposite polarity to form a solar cell is described. Two dopant films are deposited on a substrate. A laser is used to pattern the N-type dopant, by mixing the two dopant films into a single film with an exposure to the laser and/or drive the N-type dopant into the substrate to form an N-type emitter. A thermal process drives the P-type dopant from the P-type dopant film to form P-type emitters and further drives the N-type dopant from the single film to either form or further drive the N-type emitter.

    摘要： A laser system with multiple laser pulses for removing material from a solar cell being fabricated. The laser system includes a single pulse laser source and a multi-pulse generator. The multi-pulse generator receives a single pulse laser beam from the single pulse laser source and converts the single pulse laser beam into a multi-pulse laser beam. A laser scanner scans the multi-pulse laser beam onto the solar cell to remove material from the solar cell.
