Abstract
In a solar battery cell, a plurality of silver electrodes are formed in a dot shape with a predetermined gap therebetween linearly along a rear surface tab line. Pitches among the silver electrodes are set so as to be large in a central part of a silicon substrate and small at the ends of the silicon substrate. By arranging many silver electrodes at ends of the silicon substrate having a large stress, the rigidity at the ends is improved, and the warpage is decreased, thereby suppressing cell cracking.
