Solar cell and method for manufacturing the same, and solar cell module

A solar cell comprising:

• a substrate of a first conductive type;
• an emitter layer of a second conductive type opposite the first conductive type, and positioned on the substrate;
• a plurality of finger electrodes formed in a first direction, each finger electrode being electrically connected to the emitter layer;
• a plurality of first collector regions;
• a plurality of first electrodes positioned in at least one collector region and formed in the first direction;
• a plurality of second electrodes positioned in the plurality of first collector regions and formed in a perpendicular direction crossing the first direction;
• a plurality of third electrodes positioned in the plurality of first collector regions and formed in the perpendicular direction;
• and
• a plurality of fourth electrodes positioned in the plurality of first collector regions, connecting two neighboring first electrodes and formed in the perpendicular direction,
• wherein the plurality of first electrodes extend in the first direction from the plurality of finger electrodes,
• wherein a thickness and a length of the plurality of second electrodes is the same as a thickness and a length of the plurality of third electrodes,
• wherein one of the plurality of second electrodes and one of the plurality of third electrodes are positioned between a pair of first electrodes,
• wherein one of the plurality of second electrodes is positioned at portions facing one of the plurality of third electrodes in parallel, and
• wherein a plurality of deletions are positioned in the plurality of first collector regions.
