ABSTRACT:
A solar cell with integrated bypass function includes: a first conductivity type substrate 1 selected from P-type and N-type substrates; a region 2 of a second conductivity type which is opposite to the first conductivity type, the region 2 being formed on a light receiving side of the substrate; at least one third region 4 of the first conductivity type, having a higher dopant impurity concentration than the substrate 1 and being formed in a portion of the light receiving side of the substrate 1 so as to be in contact with both the substrate 1 and the region 2 of the second conductivity type; an insulator film 9 formed on at least a part of the at least one third region 4; and a light receiving side electrode 7 formed on the insulator film 9 so as to be in partial contact with the region 2 of the second conductivity type.
