Abstract

A solar cell according to an embodiment of the present invention includes a semiconductor substrate; a first conductive type region positioned at or on the semiconductor substrate; and a first electrode electrically connected to the first conductive type region. The first electrode includes a plurality of first finger lines formed in a first direction and parallel to each other; and a plurality of first bus bars including a plurality of first pad portions positioned in a second direction intersecting with the first direction. The plurality of first finger lines include a contact portion which is in direct contact with the first conductive type region. The plurality of first pad portions have a different material, a composition, or a multi-layered structure that is different from that of the plurality of first finger lines, and are spaced apart from the first conductive type region.
