Electrode structure of back contact cell, back contact cell, back contact cell module, and back contact cell system

An electrode structure of a back contact cell, the back contact cell comprising a first polarity region, a second polarity region, and a first edge, the electrode structure comprising:

• a plurality of first fingers, configured to collect the first polarity region;
• a plurality of second fingers, configured to collect the second polarity region;
• a first busbar, disposed on a side of the back contact cell close to the first edge and connected to the plurality of first fingers;
• a plurality of first pad points;
• a plurality of first connection electrodes, respectively connected to the first busbar and the first pad points, wherein a distance between each of the first pad points and the first edge is greater than a distance between the first busbar and the first edge;
• a second busbar, disposed on a side of the back contact cell close to a second edge of the back contact cell and connected to the plurality of second fingers, wherein the second edge is opposite to the first edge;
• a plurality of second pad points;
• and
• a plurality of second connection electrodes, connecting to the second busbar and the plurality of second pad points, wherein a distance between each of the plurality of second pad points and the second edge is greater than a distance between the second busbar and the second edge,
• wherein the plurality of first fingers comprise bent fingers between the second busbar and the plurality of second pad points, the bent fingers are respectively bent toward the second busbar and the plurality of second pad points, and are in contact with neither the second busbar nor the plurality of second pad points, or the bent fingers are bent toward the second busbar and are not in contact with the second busbar, or the bent fingers are bent toward the plurality of second pad points and are not in contact with the plurality of second pad points.
