PROBLEM TO BE SOLVED: To dissolve the problems of a cell such as the increase in resistance loss, which is generated with an increase in the area of a cell, such as a warpage of the cell, a crack in the cell or separation of electrodes which is generated by the thick formation of a copper foil on a busbar part, which is a countermeasure against the augmentation in the resistance loss. SOLUTION: This solar cell has a substrate, wherein a front electrode 5 consisting of a busbar part and a finger part is formed on the side of the main surface on one side of the main surfaces of a semiconductor substrate 1 having a semiconductor joint, a plurality of solar cell elements formed with a rear electrode 7 are provided on the side of the other main surface of the substrate 1 and the electrode 7 of the plurality of these solar cell elements and the electrode 5 are connected with other through a lead wire 9. In this case, the electrode 5 is provided on the busbar part by bonding a copper foil to the busbar part, and the lead wire 9 is connected with the electrode 5 from the middle part of the electrode 5 in the lengthwise direction of the copper foil. |
