Abstract
A solar cell and a method for manufacturing the same are discussed. The solar cell includes a substrate of a first conductive type, an emitter layer of a second conductive type opposite the first conductive type, a plurality of first electrodes each including a first electrode layer connected to the emitter layer and a second electrode layer positioned on the first electrode layer, at least one first current collector connected to the plurality of first electrodes, and a second electrode connected to the substrate. The emitter layer forms a p-n junction along with the substrate. The first electrode layer has a first width and the second electrode layer has a second width less than the first width of the first electrode layer.
