Abstract
An insulating strip is disposed between a top or/and bottom electrode layer and a photosensitive semiconductor layer, particularly an amorphous semiconductor layer, so that even if a groove traversing the top electrode layer and/or the semiconductor layer is formed along the insulating strip by laser scribing and damage occurs in respective layers, the damage does not affect the performance of the integrated solar cells. Thus, incorporation of a laser scribing process for dividing a solar cell is made practically possible. Moreover, application of a laser welding process for series-connection of divided parts of a solar cell is made practically possible.
