Abstract
Methods of fabricating solar cells having junctions retracted from cleaved edges, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a light-receiving surface, a back surface, and sidewalls. An emitter region is in the substrate at the light-receiving surface of the substrate. The emitter region has sidewalls laterally retracted from the sidewalls of the substrate. A passivation layer is on the sidewalls of the emitter region.
