On the other hand, Figure 13 is a main perspective view showing the installation structure of the plurality of first and second slats according to another embodiment of the present invention.

Referring to FIG. 13 , the width W1 of the first slat 121 of the present invention may be wider than the width W2 of the second slat 131 .

By making the width W1 of the plurality of first slats 121 of the upper slide part 120 provided on the upper part wider as described above, the shading function can be performed more smoothly.

In addition, the plurality of second slats 131 of the lower slide unit 130 provided at the lower portion are arranged more densely than the first slats, so that fine adjustment is possible, thereby making it easier to secure the right of view.

In addition, the plurality of first slats 121 may be formed of a solar cell panel.

In addition, the plurality of second slats 131 may be made of a solar cell panel or wood, metal, synthetic resin, glass, or organic/inorganic as a raw material, but is not limited thereto, and may be made of various other materials. .

That is, in the blind 100 of the present invention, the first slat 121 of the first blind part 120 is made of a solar cell panel, and the second slat 131 of the second blind part 130 is a solar cell. It may be composed of a slat made of any one of a panel, wood, metal, synthetic resin, glass, and materials using organic/inorganic materials as raw materials.

Therefore, the upper and lower blind parts 120 and 130, in particular, the upper blind part 120 has the effect of generating power at the same time as the shading function.

The upper blind part 120 and the lower blind part 130 may further include a separate charging member provided to charge the electric power converted into electric energy through the solar cell panel, and the charging member is electrically connected to the solar cell panel. can be connected to

Accordingly, the power converted into electrical energy through the solar cell panel is charged in a separate charging member, so that the electricity charged in the charging member can be used as needed.

In addition, since the slat of the upper blind part made of the solar cell panel has a wider width than the conventional one, the power generation efficiency can be improved by increasing the area on which sunlight is incident.

Here, since the plurality of first slats made of a solar cell panel are formed to have a wider width than in the prior art, processes such as cutting and assembling of the solar cell panel become easier.

14 is a diagram illustrating a shadow generated by a gap between slats according to an embodiment of the present invention.

Referring to FIG. 14 ( a ), when the distance between the plurality of first slats of the first blind part is densely formed as described above, in the open state, the first slat 1211 selected from among the plurality of first slats is above the first slat 1211 . A partial region of the first slat 1211 disposed below it is overlapped by the first slat 1212 disposed in the , so that a shadow is generated.

That is, according to the tilting angle of the slat, the area in which the shadow is generated by the slat disposed on the upper side is widened, so that the power generation efficiency may be reduced.

Therefore, in the present invention, as shown in FIG. 16 ( b ), by forming a larger gap ( D1 ) between the first slats, it is possible to improve the power generation efficiency by minimizing the shading between the slats.

In addition, a through hole (not shown) may be provided in each drum according to an embodiment of the present invention so that the above-described drive shaft is rotatably coupled therethrough.
