<p>A solar cell includes a substrate of a first conductive type, a plurality of first electrodes which are positioned on one surface of the substrate and extending in a first direction, an emitter region which is electrically connected to the first electrodes and is of a second conductive type opposite the first conductive type, a plurality of second electrodes which are positioned on another surface of the substrate and extending in the first direction, and a back surface field region including a plurality of first field regions which are locally formed at locations corresponding to the second electrodes in the same direction as the second electrodes and are electrically connected to the second electrodes. A distance between adjacent first field regions is less than a distance between adjacent second electrodes.</p> |
