<p>A solar cell and a method for manufacturing the same are discussed. The solar cell includes a substrate (110) of a first conductive type, an emitter region (120) of a second conductive type opposite the first conductive type, the emitter region forming a p-n junction along with the substrate, a passivation layer (190) which is positioned on a back surface of the substrate and has a plurality of via holes exposing portions of the back surface of the substrate, a first electrode (150) connected to the emitter region (120), and a second electrode (160) which is positioned on a back surface of the passivation layer and is connected to the substrate through the plurality of via holes. The passivation layer (190) includes a first passivation layer formed of amorphous silicon (191) and a second passivation layer formed of amorphous silicon nitride (192). It may further include a third passivation layer formed of silicon oxide and positioned between the back surface of the substrate (110) and the first passivation layer (191).</p> |
