    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： A carrier for use in processing of a plurality of wafers or other substrates includes a support frame on which the wafers are mounted and in one embodiment at least one auxiliary frame for holding the substrates on the support frame. A plurality of clips extend from the auxiliary frame and engage the substrates in pressure engagement, and fasteners retain the auxiliary frame in position with respect to the support frame. In one embodiment two auxiliary frames can be employed for holding wafers on opposing surfaces of the support frame. The support frame has electrically non-conducting surfaces whereby the processing does not affect the support frame, and the auxiliary frame is made of electrically non-conductive material. The clips are electrically conductive and bridge current from the support frame to the wafers during plating operations. In another embodiment, auxiliary frame are not used and the wafer retention clips are mounted on the support frame. In use, the carrier can support a high number of units for processing with no significant mechanical stress being transferred to the wafers during loading and unloading from the carrier. The carriers and wafers can be transferred easily for different chemical baths and can be handled safely during rinsing and drying steps.

    摘要： One embodiment relates to a bifacial photovoltaic module having an edge reflector. The module includes a plurality of solar cells in an array, each solar cell having a front side and a back side. A reflector is configured on an edge of the array of solar cells, the first reflector being configured to reflect light onto the front side of a row of solar cells adjacent to the edge. Another embodiment relates to a method of reducing non-uniformity of power generation from a bifacial photovoltaic module. Electrical current produced from solar cells along at least one edge of the array is increased by using a reflective strip facing towards the front side of the solar cells along the edge. Another embodiment relates to a bifacial photovoltaic module having an edge refractor. Other embodiments and features are also disclosed.
