Abstract: A wire bonding system attaches wires to a solar cell wafer. The wire bonding system includes a feed tube through which a wire is drawn. Rollers contact the wire through openings in the feed tube to facilitate movement of the wire. The wire bonding system includes a soldering heater tip and a wire cutter. The solar cell wafer is placed on a platform, which moves the solar cell wafer. The system has multiple lanes for attaching multiple wires to the solar cell wafer at the same time in parallel operations.

Abstract: A groove is cut along a line between adjacent solar cells of a wafer. A coating powder is processed to form a coating layer on the surface of the groove. The solar cells are thereafter physically separated from each other along the groove, with the coating layer serving as an edge coat. The solar cells are electrically connected in series and packaged in a solar module.

Abstract: Strings of solar cells having laser assisted metallization conductive contact structures, and their methods of manufacture, are described. For example, a solar cell string includes a first solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a first metal foil to the back side of the first solar cell. The solar cell string also includes a second solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a second metal foil to the back side of the second solar cell. The solar cell string also includes a conductive interconnect coupling the first and second solar cells, the conductive interconnect including a strain relief feature.

Abstract: A solar module includes at least one first solar cell and at least one second solar cell, each solar cell including a top side and bottom side, a bus bar, and a plurality of wires, disposed on the top side, extending from and electrically connected to the bus bar. The first solar cell overlaps a region of the second solar cell to electrically connect to the second solar cell and to form a shingled arrangement, and in the second solar cell, the plurality of wires connect to the bus bar outside of the region in which the first solar cell overlaps the second solar cell. A method of manufacturing a solar module includes shingling solar cells using ECA to make a hybrid dense solar cell string that includes at least two hybrid dense solar cells in a shingled arrangement.

Abstract: A string of solar cells is disclosed. The sides of the solar cells have a corrugated shape which forms an opening when the solar cells are arranged in a shingled manner. The solar cells are electrically connected in series by a ribbon that passes through the opening. A wire mesh used to decrease solar cell resistance is also disclosed.
