Abstract
A solar cell () includes a semiconductor substrate () having a light-receiving surface () and a back surface (); an n-type semiconductor layer () and a p-type semiconductor layer () provided on the back surface () of the semiconductor substrate (), the n-type semiconductor layer () and the p-type semiconductor layer () extending in a first direction and being adjacent to each other in a second direction intersecting with the first direction; and a ground layer () provided on the n-type semiconductor layer () and the p-type semiconductor layer (). The ground layer () includes an n-side ground layer () and a p-side ground layer () separated from each other by a first separating groove () having a first separating portion () and a second separating portion () as well as a first bridge portion () separating the first separating portion () and the second separating portion (). The first bridge portion () separates the first separating portion () and the second separating portion () at at least one of a border on the n-side ground layer () or a border on the p-side ground layer () in the first direction.
