    摘要: A method of fabricating a solar cell is disclosed. The method includes forming a polished surface on a silicon substrate and forming a first flowable matrix in an interdigitated pattern on the polished surface, where the polished surface allows the first flowable matrix to form an interdigitated pattern comprising features of uniform thickness and width. In an embodiment, the method includes forming the silicon substrate using a method such as, but not limited to, of diamond wire or slurry wafering processes. In another embodiment, the method includes forming the polished surface on the silicon substrate using a chemical etchant such as, but not limited to, sulfuric acid (H2SO4), acetic acid (CH3COOH), nitric acid (HNO3), hydrofluoric acid (HF) or phosphoric acid (H3PO4). In still another embodiment, the etchant is an isotropic etchant. In yet another embodiment, the method includes providing a surface of the silicon substrate with at most 500 nanometer peak-to-valley roughness.

    摘要: Methods of passivating light-receiving surfaces of solar cells, 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. A non-conductive anti-reflective coating (ARC) layer is disposed on the N-type silicon layer. In another example, a solar cell includes a silicon substrate having a light-receiving surface. A tunneling dielectric layer is disposed on the light-receiving surface of the silicon substrate. An N-type silicon layer is disposed on the tunneling dielectric layer. A non-conductive anti-reflective coating (ARC) layer is disposed on the N-type silicon layer.
