Abstract
Embodiments of the invention generally provide a solar cell formation process that includes the formation of metal contacts over heavily doped regions that are formed in a desired pattern on a surface of a substrate. Embodiments of the invention also provide an inspection system and supporting hardware that is used to reliably position a similarly shaped, or patterned, metal contact structure on the patterned heavily doped regions to allow an Ohmic contact to be made. The metal contact structure, such as fingers and busbars, are formed on the heavily doped regions so that a high quality electrical connection can be formed between these two regions.
