Abstract
A solar cell and a method for manufacturing the same are disclosed. The solar cell includes a semiconductor substrate containing impurities of a first conductive type, a tunnel layer positioned on the semiconductor substrate, an emitter region positioned on the tunnel layer and containing impurities of a second conductive type opposite the first conductive type, a dopant layer positioned on the emitter region and formed of a dielectric material containing impurities of the second conductive type, a first electrode connected to the semiconductor substrate, and a second electrode configured to pass through the dopant layer and connected to the emitter region.
