Abstract
A solar cell includes a substrate of a first conductive type, an emitter region, which is positioned at the substrate and is doped with impurities of a second conductive type opposite the first conductive type, a plurality of first electrodes, which are connected to the emitter region and extend parallel to one another to be spaced apart from one another, a plurality of semiconductor electrodes, which extend in a direction different from an extension direction of the plurality of first electrodes to be spaced apart from one another and have an impurity doping concentration higher than the emitter region, and a second electrode connected to the substrate. A distance between two adjacent semiconductor electrodes is about 0.02 cm to 0.2 cm, and a distance between two adjacent first electrodes is about 0.3 cm to 0.8 cm.
