<p>PURPOSE:To improve a material yield without wasteful remaining material therebetween by forming punching cutting edges in a zigzag manner when forming many thin film elements on a substrate and then individually punching with the punching cutting edge, and linearly coupling the opposed sides of the punched elements. CONSTITUTION:Many thin film photovoltaic element devices are formed in contact with a substrate 5 surrounded at both sides with guides 6 having guiding holes 7, and they are cut with the individual punching cutting edges as below. The cutting edges 1 are formed in a zigzag state, a press base 2 having holes 3 corresponding to the edge 1 is placed on the substrate 5, and guide pins 4 provided at the base 2 are engaged with the holes 7 of the substrate 5. Then, the edges 1 are pressed to the holes 3, pressure is applied to punch two unit devices 8 having end faces 9-13 at one side. Thus, the ends 11 are linearly aligned, and no wasteful remaining material exists between the devices 8. Thereafter, two devices 8 are cut out while the base 2 is displaced, and repeated.</p> |
