At this time, as shown in FIG. 9, the second insulating portion 17 is regularly insulated at positions that are alternately shifted in the width direction X2 at regular intervals (the length in the longitudinal direction X1 of the battery partition region R). A processing pattern is formed. By alternately arranging in this way, the positive electrode and the negative electrode can be regularly switched for each battery partition region R.

  Next, in the base material laminating portion 45 shown in FIG. 5, the sealing material 15 is cured by a curing processing unit (not shown), and the first base material 3 </ b> A and the second base material 3 </ b> B that are insulated are overlapped.

At this time, as shown in FIG. 11, the first insulating portion 16 of the first base material 3 </ b> A and the second insulating portion 17 of the second base material 3 </ b> B are shifted in the width direction X <b> 2 in the bonded state, As a result, a plurality of cells C that are divided and arranged in the width direction X2 through the conductive material 14 (see FIG. 3) are electrically connected in series.

Next, after bonding, in the ultrasonic fusion part 46, as shown in FIG. 12, the first base material 3A and the second base material 3B are melted by ultrasonic vibration at a constant interval in the longitudinal direction X1. The fused portion 18 is formed to extend along the width direction X2 and is divided into a plurality of battery partition regions R.

The dye-sensitized solar cell 10 having a desired length can be produced. For example, as the dye-sensitized solar cell 10 after cutting, as shown in FIG. 13, one having three battery partition regions R, one having two battery partition regions R, or four or more battery partition regions R are continuous.

By attaching the dye-sensitized solar cell 10 to the slat substrate 22, the power generation blind slat 1 can be easily manufactured. In other words, only the work for attaching the dye-sensitized solar cell 10 to the substrate 22 is performed, and after a plurality of cells are attached to the substrate as in the prior art, a wiring operation for electrically connecting the cells to each other is unnecessary. Therefore, manufacturing efficiency can be improved. Thus, since it becomes possible to reduce an operation man-hour, reduction of manufacturing cost can be aimed at.

Also in this case, a wiring that has electrical characteristics suitable for blind slats, that is, the dye-sensitized solar cell 10 in which a plurality of cells C are electrically connected by a serial wiring is a slat for power generation. Therefore, after pasting a plurality of cells on a slat substrate as in the prior art, a wiring operation for electrically connecting the cells C to each other is not necessary, so that manufacturing efficiency can be improved. Thus, since only the manufacturing process of the dye-sensitized solar cell 10 is possible and the number of work steps can be reduced, the manufacturing cost can be reduced. In addition, since the dye-sensitized solar cell 10 is in a state in which a plurality of cells C, C,...
