A method for manufacturing a solar cell, includes: forming a photoelectric converter (12) which includes a plurality of compartment elements (21, 21s), and in which the compartment elements (21, 21s) adjacent to each other are electrically connected; specifying a compartment element (21s) having a structural defect (R, A1, A2, A3) in the photoelectric converter (12); restricting a portion in which the structural defect (R, A1, A2, A3) exists in the compartment element (21s) by specifying a defect portion based on a resistance distribution that is obtained by measuring resistances of portions between the compartment elements (21, 21s) adjacent to each other; and removing the structural defect (R, A1, A2, A3) by supplying a bias voltage to the portion in which the structural defect (R, A1, A2, A3) exists.
