摘要： Described herein are methods of fabricating solar cells. In an example, a method of fabricating a solar cell includes forming an amorphous dielectric layer on the back surface of a substrate opposite a light-receiving surface of the substrate. The method also includes forming a microcrystalline silicon layer on the amorphous dielectric layer by plasma enhanced chemical vapor deposition (PECVD). The method also includes forming an amorphous silicon layer on the microcrystalline silicon layer by PECVD. The method also includes annealing the microcrystalline silicon layer and the amorphous silicon layer to form a homogeneous polycrystalline silicon layer from the microcrystalline silicon layer and the amorphous silicon layer. The method also includes forming an emitter region from the homogeneous polycrystalline silicon layer.

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： Approaches for foil-based metallization of solar cells and the resulting solar cells are described. For example, a method of fabricating a solar cell involves locating a metal foil above a plurality of alternating N-type and P-type semiconductor regions disposed in or above a substrate. The method also involves laser welding the metal foil to the alternating N-type and P-type semiconductor regions. The method also involves patterning the metal foil by laser ablating through at least a portion of the metal foil at regions in alignment with locations between the alternating N-type and P-type semiconductor regions. The laser welding and the patterning are performed at the same time.
