The glass substrate is processed to a smooth finish without causing cracking or breakage.

Abstract: A solar cell module comprises a plurality of unit cells connected in series, each of the unit cells comprising in this order an electrode, a first semiconductor layer having a first conductivity type and a second semiconductor layer having a second conductivity type. The electrode has a region not covered with the first semiconductor layer. The second semiconductor layer has a main region and a subregion which are separated by a groove. The main region of the second semiconductor layer in one unit cell is electrically connected to the region of the electrode not covered with the first semiconductor layer in another unit cell adjacent to the one unit cell. The region of the electrode not covered with the first semiconductor layer in the one unit cell is electrically connected to the subregion of the second semiconductor layer in the another unit cell. With this structure, it is possible to simplify the formation of a bypass diode and therefore provide a solar cell module with high reliability at a low cost.
