Abstract:
A solar cell includes a substrate formed of n-type single crystal silicon, an emitter region of a p-type which is positioned at a first surface of the substrate and includes a first emitter region having a first sheet resistance and a second emitter region having a second sheet resistance less than the first sheet resistance, a plurality of surface field regions of the n-type locally positioned at a second surface opposite the first surface of the substrate, a plurality of first electrodes which are positioned only on the second emitter region to be separated from one another and are connected to the second emitter region, and a plurality of second electrodes which are positioned on the plurality of surface field regions to be separated from one another and are connected to the plurality of surface field regions.

Claim (Index 1):
A solar cell comprising:\n a substrate having a first conductive type impurity; an emitter region positioned at a first surface of the substrate, the emitter region forming a p-n junction along with the substrate; a surface field region positioned at a second surface opposite the first surface of the substrate, the surface field region having the first conductive type impurity more heavily doped than that of the substrate; a plurality of first electrodes positioned on the emitter region to be separated from one another and connected to the emitter region; a plurality of second electrodes positioned on the surface field region to be separated from one another and connected to the surface field region; a first anti-reflection layer positioned on the first surface of the substrate, the second surface of the substrate, and a third surface of the substrate other than the first and second surfaces of the substrate, the first anti-reflection layer which is formed of aluminum oxide and has negative fixed charges; a second anti-reflection layer positioned on the first anti-reflection layer at the first surface and the third surface of the substrate, the second anti-reflection layer which is formed of silicon nitride and has positive fixed charges; and a passivation layer positioned between the second surface of the substrate and the first anti-reflection layer, wherein each of the first anti-reflection layer and the passivation layer has a plurality of openings where the plurality of second electrodes penetrate therethrough on the second surface of the substrate.
