Abstract
In a method of manufacturing a solar cell, a groove is formed on a first surface of an n-type semiconductor substrate. A p-side transparent conductive film layer is formed on the first surface of the n-type semiconductor substrate formed with the groove. A non-deposition area, where the p-side transparent conductive film layer is not formed, is formed in at least a part of a side surface of the groove formed on the first surface of the n-type semiconductor substrate.
