Abstract
A solar cell includes a first conductivity type substrate; an emitter unit having a second conductivity type opposite to the first conductivity type, and forming a p-n junction with the substrate; an anti-reflective film positioned on the emitter unit; a plurality of first electrodes positioned on the anti-reflective film and connected with the emitter unit; and a second electrode connected with the substrate, wherein the emitter unit includes a first region and a second region that are positioned between an outermost first electrode among the plurality of first electrodes and the edge of the substrate, and a thickness of the first region gradually increases in going from the edge of the substrate to the outermost first electrode, and a thickness of the second region is uniform.
