    摘要: A improved, lower cost method of producing solar cells utilizing selective emitter design is disclosed. The contact regions are created on the substrate without the use of lithography or masks. The method utilizes ion implantation technology, and the relatively low accuracy requirements of the contact regions to reduce the process steps needed to produce a solar cell. In some embodiments, the current of the ion beam is selectively modified to create the highly doped contact regions. In other embodiments, the ion beam is focused, either through the use of an aperture or via adjustments to the beam line components to create the necessary doping profile. In still other embodiments, the wafer scan rate is modified to create the desired ion implantation pattern.

    摘要: The manufacture of solar cells is simplified and cost reduced through by performing successive ion implants, without an intervening thermal cycle. In addition to reducing process time, the use of chained ion implantations may also improve the performance of the solar cell. In another embodiment, two different species are successively implanted without breaking vacuum. In another embodiment, the substrate is implanted, then flipped such that it can be and implanted on both sides before being annealed. In yet another embodiment, one or more different masks are applied and successive implantations are performed without breaking the vacuum condition, thereby reducing the process time.

    摘要: An improved, lower cost method of processing substrates, such as to create solar cells is disclosed. The doped regions are created on the substrate, using a mask or without the use of lithography or masks. After the implantation is complete, visual recognition is used to determine the exact region that was implanted. This information can then be used by subsequent process steps to maintain this alignment. This information can also be fed back to the ion implantation equipment to modify the implant parameters. These techniques can also be used in other ion implanter applications.
