Abstract
A solar cell and a method of manufacturing the same are disclosed. The solar cell includes a substrate of a first conductive type having at least one via hole; an emitter layer only on at least a portion of the via hole and at least one selected from a group consisting of an incident surface and side surfaces of the substrate, the emitter layer having a second conductive type opposite the first conductive type; at least one first electrode on the incident surface, the first electrode being electrically connected to the emitter layer; a second electrode connected to an opposite surface to the incident surface; and at least one first electrode current collector on the opposite surface, the at least one first electrode current collector being insulated from the second electrode and being electrically connected to the at least one first electrode through the via hole.
