Abstract
A solar cell and a method of forming a solar cell comprising: a semiconductor body having a p-n junction located between a front (light receiving) semiconductor region and a back (non-light receiving) semiconductor region; a dielectric layer extending over a front surface of the front semiconductor region; one or more elongate semiconductor fingers formed on the front surface of the front semiconductor region, the semiconductor fingers being exposed through the dielectric layer, more heavily doped than the remainder of the front semiconductor region and of the same dopant polarity; one or more elongate plated contacts formed to self align with and at least partially cover the semiconductor fingers; one or more metal collection fingers extending over the dielectric layer, generally transversely to the plated contacts.
