    摘要: Embodiments of the present disclosure provide a solar cell and a solar cell module. The solar cell includes a first region and a second region, and further includes a substrate having a first surface and a second surface; a tunneling layer covering the second surface; a first emitter formed on part of the tunneling layer in the first region; and a second emitter formed on part of the tunneling layer in the second region and on the first emitter, a conductivity type of the second emitter being different from a conductivity type of the first emitter. The solar cell further includes a first electrode configured to electrically connect with the first emitter by penetrating through the second emitter; and a second electrode formed in the second region and configured to electrically connect with the second emitter.

    摘要: Methods of fabricating solar cell emitter regions using ion implantation, and resulting solar cells, are described. In an example, a back contact solar cell includes a crystalline silicon substrate having a light-receiving surface and a back surface. A first polycrystalline silicon emitter region is disposed above the crystalline silicon substrate. The first polycrystalline silicon emitter region is doped with dopant impurity species of a first conductivity type and further includes ancillary impurity species different from the dopant impurity species of the first conductivity type. A second polycrystalline silicon emitter region is disposed above the crystalline silicon substrate and is adjacent to but separated from the first polycrystalline silicon emitter region. The second polycrystalline silicon emitter region is doped with dopant impurity species of a second, opposite, conductivity type. First and second conductive contact structures are electrically connected to the first and second polycrystalline silicon emitter regions, respectively.
