    Abstract: Provided is a solar cell comprising a photoelectric conversion unit on which textures are formed, and an electrode that includes a plurality of conductive particles. The average size of the textures is adjusted so that the diameter of an inscribed circle in a space surrounded by the ridgelines of a plurality of textures that are adjacent to each other in the textures and a virtual line that connects the vertices of the adjacent textures is smaller than the average particle size of the conductive particles.

    Abstract: A first finger electrode group including finger electrodes on the first principal surface. A second finger electrode group including finger electrodes on the second principal surface. The second finger electrode group is divided into divided electrode portions, the number of electrodes of the electrode portions decreasing as a distance from a central portion of the second finger electrode group increases towards outside, and a coupling portion is arranged between each adjacent ones of the divided electrode portions and electrically connects at least two of the finger electrodes of the divided electrode portion on inside with at least one of the finger electrodes of the divided electrode portion on outside. The number of finger electrodes of the divided electrode portion closest to the central portion of the second finger electrode group is larger than the number of finger electrodes of the first finger electrode group.
