Abstract
A solar cell includes a substrate of a first conductive type, a plurality of first electrodes positioned on one surface of the substrate in parallel with one another, and a plurality of back surface field regions which are positioned respectively correspondingly to the plurality of first electrodes, are separated from one another, and are doped with impurities of the first conductive type at a concentration higher than the substrate. Each back surface field region includes discontinuous regions in a longitudinal direction of the first electrodes. An impurity concentration of the discontinuous regions is lower than an impurity concentration of the back surface field region.
