Abstract
A method for manufacturing a solar cell comprising forming a series of transparent electrode layer material films on electroconductive semiconductor layers on the reverse surface side of a substrate; forming metal electrode layers on the transparent electrode layer material films; forming insulation layers covering the entirety of the metal electrode layers except for a first non-insulation region, and insulation layers covering the entirety of the metal electrode layers excluding a second non-insulation region; and forming patterned transparent electrode layers and leaving the insulation layers using an etching technique in which the insulation layers are masks. In the insulation layer formation, the first non-insulation region positioned on a first straight line extending in a first direction is formed in the insulation layers, and the second non-insulation region positioned on a second straight line, different from the first straight line, extending in the first direction is formed in the insulation layers.
