Abstract: Provided is a solar cell and a solar cell module. The solar cell includes a converging busbar. The converging busbar separates a first surface of the solar cell into a first region and a second region. The first region includes a plurality of first sub-busbars spaced along a first direction and a plurality of main busbars spaced along a second direction, and the main busbar is electrically connected to the first sub-busbar. The second region includes a plurality of second sub-busbars spaced along a third direction. The converging busbar is located between the first region and the second region, and is electrically connected to the plurality of main busbars and the plurality of second sub-busbars.

Abstract: Provided is a device and method for repairing photovoltaic cell string. The device for repairing photovoltaic cell string includes: a conveying device and a baking device. The conveying device is configured to drive a photovoltaic cell string placed on the conveying device to reciprocate along a first direction. The conveying device includes a first conveying component, a second conveying component and a third conveying component separately arranged. The baking device is arranged toward the second conveying component. The baking device is configured to heat the photovoltaic cell string located on the second conveying component, so that a protruding solder strip of a solar cell on the photovoltaic cell string is separated or fused at its connecting part.

Abstract: The present disclosure provides a photovoltaic stringer and a method for manufacturing a photovoltaic ribbon. The photovoltaic stringer includes a first clamping component to pull a ribbon from a ribbon reel, a second clamping component to coordinate with the first clamping component to stretch the ribbon, a cutting component to cut the ribbon, and, at least one first electrode and at least one second electrode to supply power to the ribbon. The method for manufacturing a photovoltaic ribbon comprises acquiring a ribbon reel and pulling a ribbon, stretching the ribbon and cutting the ribbon to obtain a cut ribbon, and performing an annealing process on the cut ribbon.
