Abstract (en)
[origin: WO2011107089A2] The invention relates to a solar cell (1), comprising a substrate (2), a semiconductor layer (3), a first busbar (4) on a first surface (5) of the semiconductor layer (3), and a second busbar (6) on a second surface (7) of the semiconductor layer (3), wherein the first busbar (4) has contact pads (9, 9') along a connecting line (8), said contact pads having a maximum width blmax perpendicular to the connecting line (8), a current collecting area (10) being located between the contact pads on the connecting line (8), the current collecting area contacting the contact pads (9, 9') in a contact area (11), wherein the contact area (11) has two outer points (P1) and (P2) on both sides of the connecting line (8), the distance of which outer points perpendicular to the connecting line (8) defines a maximum width bSmax of the current collecting area (10), wherein blmaxSmax, and the width b of the current collecting area (10), starting from one contact pad (9) to an adjacent contact pad (9'), first decreases to a minimum width bSmin between two inner points (P3) and (P4) and then increases again to the adjacent contact pad (9') to a maximum width bSmax'.
