Abstract

A method for manufacturing a solar cell having an improved process and a solar cell manufactured by the method include a semiconductor substrate having a via hole, an emitter portion, a base portion, a first electrode, and a second electrode. The emitter portion and the base portion form a p-n junction in the semiconductor substrate. The first electrode is electrically connected to the emitter portion, and the second electrode is electrically connected to the base portion. Conductive crystals are formed to electrically connect a first electrode portion of the first electrode and the emitter portion to increase the efficiency of the solar cell.
