A solar cell, a solar cell manufacturing device, and a method for manufacturing the solar cell are discussed. The solar cell manufacturing device includes a chamber; an ion implantation unit configured to implant ions into a substrate inside the chamber and a mask positioned between the ion implantation unit and the substrate. The mask includes a first opening to form a lightly doped region having a first concentration at one surface of the substrate, a second opening to form a heavily doped region having a second concentration higher than the first concentration at the one surface of the substrate, and at least one connector formed to cross the second opening. The second opening includes finger openings formed in a first direction, and bus openings formed in a second direction crossing the first direction.
