Abstract
A solar cell includes a semiconductor substrate, an emitter region positioned at the semiconductor substrate, a first electrode which is positioned on the semiconductor substrate and is connected to the emitter region, a second electrode which is positioned on the semiconductor substrate and is connected to the semiconductor substrate, and a second electrode current collector which is positioned on the semiconductor substrate and is connected to the second electrode. An overlap distance between the second electrode and the second electrode current collector in a first direction corresponding to an extension direction of a conductive film positioned on the second electrode current collector is less than an overlap distance between the second electrode and the second electrode current collector in a second direction crossing the first direction.
