Abstract:

Methods of fabricating solar cells having passivation layers, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a first surface and a second surface. A plurality of emitter regions is disposed on the first surface of the substrate and spaced apart from one another. An amorphous silicon passivation layer is disposed on each of the plurality of emitter regions and between each of the plurality of emitter regions, directly on an exposed portion of the first surface of the substrate.
