    摘要: A method of processing of solar cells includes determining that a back-contact solar cell is defective. The back-contact solar cell includes a first plurality of interconnect pads at a first edge thereof, and a second plurality of interconnect pads at a second, opposed thereof, the first and second pluralities of interconnect pads having opposite operational charges. The back-contact solar cell is then diced to define at least first and second back-contact solar cell sections. The first back-contact solar cell section has at least two interconnect pads, of the plurality of interconnect pads, at respective opposed edges thereof.

    摘要: A solar cell is fabricated by etching one or more of its layers without substantially etching another layer of the solar cell. In one embodiment, a copper layer in the solar cell is etched without substantially etching a topmost metallic layer comprising tin. For example, an etchant comprising sulfuric acid and hydrogen peroxide may be employed to etch the copper layer selective to the tin layer. A particular example of the aforementioned etchant is a Co-Bra Etch® etchant modified to comprise about 1% by volume of sulfuric acid, about 4% by volume of phosphoric acid, and about 2% by volume of stabilized hydrogen peroxide. In one embodiment, an aluminum layer in the solar cell is etched without substantially etching the tin layer. For example, an etchant comprising potassium hydroxide may be employed to etch the aluminum layer without substantially etching the tin layer.

    摘要: Solar cell interconnects with multiple current paths. A solar cell interconnect may include a plurality of in-plane slits arranged in several rows. The in-plane slits may be spaced to provide strain relief without unduly increasing the electrical path resistance through the solar cell interconnect. The in-plane slits may be staggered, for example.

    摘要: In one embodiment, a solar cell module comprises a plurality of solar cells interconnected as a solar cell array. An interconnect assembly electrically connects the backsides of two adjacent solar cells. The interconnect assembly may have an interconnect that electrically connects a contact point on a backside of a solar cell to a contact point on a backside of another solar cell. The interconnect assembly may further include an interconnect shield placed between the solar cells and the interconnect.
