Abstract
A solar cell having an improved electrode structure includes a semiconductor substrate having a via hole, an emitter portion, a base, a first electrode, and a second electrode. The semiconductor substrate includes a first surface and a second surface opposite to each other. The emitter portion is formed adjacent to the first surface of the semiconductor substrate and extends to the second surface of the semiconductor substrate through a portion adjacent to the via hole. The first electrode includes a first electrode portion formed on the first surface of the semiconductor substrate. The first electrode portion includes a first portion having a first width and a second portion having a second width larger than the first width, and the second portion corresponds to the via hole.
