In the embodiment of the present invention, the first current collecting strap 21 is connected with the bottom electrode of the perovskite solar cell unit 10 by welding, so that holes or electrons generated by the perovskite solar cell unit 10 are respectively conducted into the first current collecting strap 21. Of course, the connection relationship between the perovskite solar cell 10 and the first current collecting tape 21 is not limited thereto, and a connection member having good conductivity may be provided between the perovskite solar cell and the first current collecting tape 21, and the perovskite solar cell and the first current collecting tape may be conducted through the connection member.

The second end of the first current collecting strap 21 is also provided with insulation so that the non-conductive section 34 of the second zoned conductive drawstring 32 has the same function as the non-conductive section 34 of the first zoned conductive drawstring 31, while further reducing the number of parts of the shutter power generation integration device. Holes or electrons in the first current collecting strip 21 are conducted only from the first end of the first current collecting strip 21 to the conductive segment 33 of the first zoned conductive pull cord 31.

Here, the first current collecting tape 21 and the second current collecting tape 22 extend along the length direction of the perovskite solar cell 10, and both ends of the first current collecting tape 21 protrude from the inside of the encapsulation layer, respectively, and both ends of the second current collecting tape 22 protrude from the inside of the encapsulation layer, respectively, so as to be connected to the first partition conductive pull rope 31 and the second partition conductive pull rope 32.
It should be noted that, the encapsulation layer may encapsulate only the perovskite solar cell 10, the encapsulation layer is provided with a connection element, the first current collecting strap 21 is connected to the bottom electrode of the perovskite solar cell 10 through the connection element at the encapsulation layer, and the second current collecting strap 22 is connected to the top electrode of the perovskite solar cell 10 through the connection element at the encapsulation layer.

When the perovskite solar cell 10 is packaged with other types of louver blades, the obtained louver blades can meet the curvature design, aesthetic design and color requirements of different blades, and achieve customized properties matching existing building materials.
It should be noted that other types of photovoltaic blind slats may be photovoltaic blind slats such as crystalline silicon cells or thin film batteries. Specifically, the crystalline silicon cell includes one of a passivated emitter and back cell (PERC) solar cell, a tunnel oxide passivation contact (TOPCon) solar cell, and an intrinsic thin film Heterojunction (HJT) solar cell, and the thin film cell includes one of a Copper Indium Gallium Selenium (CIGS) solar cell, a gallium arsenide (GaAs) solar cell, and a perovskite solar cell.
