Abstract: A solar cell includes a substrate of a first conductive type, a first doped region positioned at a first surface of the substrate and contains impurities of a second conductive type different from the first conductive type, and a first electrode part electrically connected to the first doped region. The first electrode part includes a thermosetting resin, and first and second conductive particles distributed in the thermosetting resin. The second conductive particles have a work function greater than the first conductive particles and form silicide at an interface contacting the first doped region.
