Abstract
A solar cell includes: first conductivity-type layers and second conductivity-type layers each provided on a rear surface of a semiconductor substrate; first electrodes provided on the first conductivity-type layers; and second electrodes provided on the second conductivity-type layers. The first electrodes and the second electrodes are spaced apart from each other, and the first electrodes include a plurality of regions isolated from one another by the second electrodes disposed therebetween. Each of the plurality of regions of the first electrodes includes a non-mounting electrode section and a wiring-mounting electrode section having a larger electrode height than the non-connection electrode section. In two adjacent first electrode regions, an imaginary line connecting the top of the wiring-mounting electrode section of one of the regions and the top of the wiring-mounting electrode section of the other region does not cross the second electrode disposed between the two regions.
