    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: A method and system can compensate for anneal non-uniformities by implanting dopant in a pattern to provide higher dopant concentrations where the anneal non-uniformities result in lower active dopant concentrations. A pattern for the anneal non-uniformities may be determined by annealing a wafer having a uniform dopant distribution and measuring properties of the wafer after annealing, e.g., by obtaining a sheet resistance map of the wafer. In one embodiment, the non-uniformities may be measured by measuring temperature variations during annealing.

The first and second angles are opposite in sign with respect to a reference direction and in magnitude are equal to or greater than the measured angle of non-parallelism. Preferably, the first and second implants are controlled to provide substantially equal ion doses in the workpiece.
