Abstract:
1. A method of providing electrical interconnection between solar substrates, the method comprising the steps of: (a) ultrasonically bonding a first ribbon material to a first side of ones of a plurality of solar substrates using a first bonding tool of a first ribbon bonder, the first ribbon material being fed from a first ribbon supply to a position proximate the first bonding tool using a first ribbon feeding system; (b) flipping ones of the plurality of solar substrates after step (a) to expose an opposite, second side of the plurality of solar substrates; and (c) ultrasonically bonding a second ribbon material to the second side of ones of the plurality of solar substrates using a second bonding tool of a second ribbon bonder, the second ribbon material being fed from a second ribbon supply to a position proximate the second bonding tool using a second ribbon feeding system.
