Abstract
A solar cell includes a semiconductor substrate of a first conductive type and includes a first side and a second side, the second side having a textured structure formed on the entire second side; a first doped region of the first conductive type and a second doped region of a second conductive type on the first side; a first passivation layer on the first doped region and the second doped region and exposing a portion of a back surface of each of the first and second doped regions, the first passivation layer being formed of silicon nitride (SiNx), silicon dioxide (SiOx), or a combination thereof; a second passivation layer on the second side; an anti-reflection layer on the second passivation layer; and a first electrode electrically connected to the first doped region and a second electrode electrically connected to the second doped region.
