A solar cell is discussed, and includes a substrate; a first field region; a first electrode directly formed on an emitter region; and a second electrode directly formed on a second field region, wherein a second passivation layer comprises a first back passivation portion and a second back passivation portion. Furthermore, the first back passivation portion is merely positioned between the emitter region and the substrate and the second field region and the substrate, and the second back passivation portion is positioned between the emitter region and the second field region, and wherein the first back passivation portion positioned between the emitter region and the substrate is physically separated from first back passivation portion positioned between the second field region and the substrate.
