Abstract
An aspect of the invention provides a solar cell that comprises a semiconductor substrate having a light-receiving surface and a rear surface; a first semiconductor layer having a first conductivity type; a second semiconductor layer having a second conductivity type, the first semiconductor layer and the second semiconductor layer being formed on the rear surface, and a trench formed in the rear surface, wherein the first semiconductor layer is formed on the rear surface in which the trench is not formed, and the second semiconductor layer is formed on a side surface of the trench in an arrangement direction in which the first semiconductor layer and the second semiconductor layer are alternately arranged and on a bottom surface of the trench.
