摘要: A solar cell includes a semiconductor substrate having a photoelectric converting portion, a first electrode formed on a first main surface of the semiconductor substrate, and a second electrode connected to the first electrode on the first main surface. The first electrode includes a plurality of first connecting portions to be connected to an interconnector and a first non-connecting portion not connected to an interconnector. The first non-connecting portion is arranged between first connecting portions to electrically connect the first connecting portions together. The first connecting portion and first non-connecting portion are coupled forming an angle larger than 90° and smaller than 180°. A solar cell string and a solar cell module employ the solar cells.
