A solar cell includes a substrate; a first passivation layer on a first surface of the substrate; a first field region on the first surface of the substrate; an anti-reflection layer on the first passivation layer; a second passivation layer on a second surface of the substrate; an emitter region on the second passivation layer, the emitter region forming a p-n junction and a hetero-junction junction with the substrate; a second field region on the second passivation layer, the second field region forming a hetero-junction with the substrate; a first electrode contacted to the emitter region; a second electrode contacted to the second field region; a spacing between the emitter region and the second field region; and a third passivation layer on the second surface of the substrate at the spacing.
