A solar cell is provided with a semiconductor substrate including a light-receiving surface, a back surface, a first region of a first conductivity type disposed on the back surface, a second region of a second conductivity type disposed on the light-receiving surface, and a PN junction at the boundary between the first and second regions. An electrode is provided on the light-receiving surface to expose a portion of the light-receiving surface, and the semiconductor substrate includes a plurality of recesses formed by recessing the exposed portion of the light-receiving surface. The recesses may function as a texturing structure.
