Abstract
A solar cell and a method of forming a contact structure on a solar cell having a p-n junction formed between a first semiconductor region of a first dopant polarity and a second semiconductor region of a second dopant polarity opposite to the first dopant polarity. The method comprises: forming a plurality of contact points on a surface of the solar cell, whereby the contact points provide an electrical connection to the first semiconductor region; and locating a plurality of conducting wires over the solar cell to make electrical connection to the contact points. The contact points are either an exposed silicon surface or a silicon surface over which metal pads are formed. The metal pads may comprise a plated layer of a low-melting temperature metal and/or may have a thickness of less than 5 microns.
