Abstract

See full text

A method for manufacturing a solar cell having a P-type silicon substrate wherein one main surface is a light-receiving surface and another is a backside, a plurality of back surface electrodes formed on a part of the backside, an N-type layer in at least a part of the light-receiving surface, and contact areas in which the substrate contacts the electrodes; wherein the P-type silicon substrate is a silicon substrate doped with gallium and has a resistivity of 2.5 Ω·cm or less; and a back surface electrode pitch Prm [mm] of contact areas in which the P-type silicon substrate is in contact with the back surface electrodes and the resistivity Rsub [Ω·cm] of the substrate satisfy the relation represented by the following formula (1).
