Claim 0:
1. A method for welding a cell string, comprising:
providing a plurality of solar cells and forming an arrangement of the plurality of solar cells;
performing inspections on the arrangement of the plurality of solar cells, wherein the inspections include polarity inspections, in response to the polarity inspections not passing, adjusting the arrangement of the plurality of solar cells until the polarity inspections on an adjusted arrangement of the plurality of solar cells pass;
in response to the polarity inspections on the adjusted arrangement of the plurality of solar cells passing:
placing the adjusted arrangement of the plurality of solar cells on a welding table;
providing a plurality of initial welding strips arranged at intervals in a first direction, wherein each of the plurality of initial welding strips extends in a second direction, and wherein the plurality of initial welding strips include first initial welding strips and second initial welding strips, and the first initial welding strips interleave with the second initial welding strips in the first direction;
cutting each respective initial welding strip of the plurality of initial welding strips along the first direction to obtain a plurality of welding strips, wherein each of the first initial welding strips is cut at one or more first cutting positions, and each of the second initial welding strips is cut at one or more second cutting positions;
moving each welding strip of the plurality of welding strips in the second direction to form a set of welding strips having a spacing between each two adjacent welding strips of the plurality of welding strips in the second direction;
transferring the set of welding strips onto the adjusted arrangement of the plurality of solar cells such that each welding strip of the set of welding strips contacts with a peripheral solar cell of the adjusted arrangement of the plurality of solar cells or with two respective adjacent solar cells of the adjusted arrangement of the plurality of solar cells; and
welding each welding strip of the plurality of welding strips to the peripheral solar cell of the adjusted arrangement of the plurality of solar cells or to the two respective adjacent solar cells of the adjusted arrangement of the plurality of solar cells, to form a cell string.
