Abstract: A solar cell includes a substrate, a semiconductor layer, a first busbar, and a second busbar. Along a connecting line, the first busbar has contact pads which have a maximum width bImax, perpendicular to the connecting line and between which there is respectively located on the connecting line a current collecting area which makes contact with the contact pads in a contact area, having on both sides of the connecting line two outer points whose spacing perpendicular to the connecting line defines a maximum width bSmax of the current collecting area. Width b of the current collecting area and bImax<bSmax, starting from one contact pad up to an adjacent contact pad, decreases down to a minimum width bSmin between two inner points, and then increases up to the adjacent contact pad to a maximum width bSmax?.
