    摘要: Methods of fabricating a solar cell, and resulting solar cell are described. In an example, the method for fabricating a solar cell include forming an oxide region over a light receiving region of a silicon substrate. The method can include forming an interfacial region over the light receiving surface of the silicon substrate. The method can also include forming a first surface region comprising aluminum oxide over the interfacial region and forming a second surface region over the first surface region. In some embodiments, the first surface region can have a thickness greater than the second surface region. In one embodiment, the second surface region can have a thickness greater than the thickness of the first surface region.

    摘要: Methods of passivating light-receiving surfaces of solar cells with high energy gap (Eg) materials, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the substrate. A Group III-nitride material layer is disposed above the passivating dielectric layer. In another example, a solar cell includes a substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the substrate. A large direct band gap material layer is disposed above the passivating dielectric layer, the large direct band gap material layer having an energy gap (Eg) of at least approximately 3.3. An anti-reflective coating (ARC) layer disposed on the large direct band gap material layer, the ARC layer comprising a material different from the large direct band gap material layer.
