PASSIVATION OF LIGHT-RECEIVING SURFACES OF SOLAR CELLS WITH CRYSTALLINE SILICON

Methods of passivating light-receiving surfaces of solar cells with crystalline silicon, and the resulting solar cells, are described. In an example, a solar cell includes a silicon substrate having a light-receiving surface. An intrinsic silicon layer is disposed above the light-receiving surface o...

Summary:Methods of passivating light-receiving surfaces of solar cells with crystalline silicon, and the resulting solar cells, are described. In an example, a solar cell includes a silicon substrate having a light-receiving surface. An intrinsic silicon layer is disposed above the light-receiving surface of the silicon substrate. An N-type silicon layer is disposed on the intrinsic silicon layer. One or both of the intrinsic silicon layer and the N-type silicon layer is a micro- or poly-crystalline silicon layer. In another example, a solar cell includes a silicon substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the silicon substrate. An N-type micro- or poly-crystalline silicon layer disposed on the passivating dielectric layer.
