    摘要: A photovoltaic module and a method for manufacturing the photovoltaic module are provided. The photovoltaic module includes a battery module including multiple cell string groups and multiple first connection structures. Each cell string group includes multiple cell strings arranged along a first direction. Each cell string includes multiple solar cells and multiple second connection structures. Each solar cell includes multiple first grid lines and multiple second grid lines. There is a distance L between a first grid line and a second grid line adjacent to the first grid line in the first direction. A second connection structure connected to an end of a respective middle first connection structure is spaced apart by a distance S in the first direction from an adjacent second connection structure connected to an end of another middle first connection structure adjacent to the respective middle first connection structure and the distance S is greater than the distance L.

    摘要: A first surface of the solar cell has multiple first electrodes and multiple second electrodes staggered in an interdigitated pattern. Each of the multiple first electrodes has a first busbar and multiple first fingers, and each of the multiple second electrodes has a second busbar and multiple second fingers extending along the second direct. A first welding point is defined on the first busbar, and a second welding point is defined on the second busbar. The solar cell further includes multiple insulation structures. Each of the multiple insulation structures extends to cover ends of the multiple first fingers. A window is opened on a projection of at least one of the first busbar and the first welding point on a respective insulation structure, and/or a window is opened on a projection of at least one of the second busbar and the second welding point on the respective insulation structure.

    摘要: The photovoltaic module includes at least one cell string, including multiple solar cell sheets, and adjacent solar cell sheets in the multiple solar cell sheets are connected to each other by multiple welding strips. In some embodiments, the photovoltaic module further includes multiple welding strips, where each of the multiple welding strips is in electrical contact with a corresponding bus bar, each of the multiple welding strips includes multiple bending portions arranged continuously along a second direction. In addition, along the second direction, an orthographic projection of a central line of each of the multiple welding strips on a back surface of the solar cell sheet coincides with an orthographic projection of a central line of the corresponding bus bar and/or an orthographic projection of a central line of each of the multiple bonding pads on the corresponding bus bar on the back surface of the solar cell sheet.
