Abstract
A method of processing of solar cells includes determining that a back-contact solar cell is defective. The back-contact solar cell includes a first plurality of interconnect pads at a first edge thereof, and a second plurality of interconnect pads at a second, opposed thereof, the first and second pluralities of interconnect pads having opposite operational charges. The back-contact solar cell is then diced to define at least first and second back-contact solar cell sections. The first back-contact solar cell section has at least two interconnect pads, of the plurality of interconnect pads, at respective opposed edges thereof.
