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.
