[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0026] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0027] This utility model provides a BIPV color steel tile assembly, as shown in the schematic diagram. Figure 1 As shown, the BC solar cell 400 is embedded in the solar cell receiving groove 200 of the color steel roofing plate 100, specifically including: A color steel tile back panel 100 is provided with a battery cell receiving groove 200 and a wire receiving groove 300 connecting the two battery cell receiving grooves 200. BC solar cell 400, the back side of which is in contact with the bottom of the solar cell receiving groove 200; The wire 500 is located in the wire receiving groove 300 and is connected between the positive electrode 420 and the negative electrode 410 of two adjacent BC solar cells 400. The color steel tile back plate 100, the BC solar cells 400 and the wire 500 constitute a BIPV module. The front glass 700 is disposed on the side of the BIPV module near the solar cells; An adhesive film 600 is disposed between the BIPV assembly and the front glass 700.

[0028] In the BIPV color steel tile assembly provided in this application, BC solar cells 400 are used instead of the topcon and perc solar cells in traditional BIPV color steel tile assemblies, which broadens the application of solar cells. At the same time, since the BC solar cells 400 can have an aesthetically pleasing all-black front and high low-light response efficiency, it helps to improve the aesthetics of the BIPV color steel tile assembly. Furthermore, by opening solar cell receiving grooves 200 and wire receiving grooves 300 on the back plate 100 of the color steel tile, the BC solar cells 400 can be embedded in the solar cell receiving grooves 200. The BC solar cells 400 can also be connected by wires 500 embedded in the wire receiving grooves 300. In this way, the BIPV color steel tile assembly can be encapsulated using a single layer of adhesive film 600, which helps to reduce costs and also better protects the BC solar cells 400, reducing mechanical damage to the solar cells.

[0029] In an optional embodiment, in the BIPV assembly, the front surface of the BC solar cell 400 is flush with the surface of the color steel roofing plate 100.

[0030] On the one hand, this allows the BC cell 400 to be fully embedded in the cell receiving groove 200, which enables the cell receiving groove 200 to better position and protect the BC cell 400. On the other hand, during subsequent encapsulation, the pressure on the cell is almost the same as the pressure on the surface of the color steel tile back plate 100, which helps to distribute the force and reduce the probability of damage to the BC cell 400.

[0031] In an optional embodiment, the cell receiving slot 200 is adapted to the shape and size of the BC cell 400.

[0032] The cell receiving groove 200 can position and protect the BC cell 400. When the shape and size of the cell receiving groove 200 are matched with the BC cell 400, even if it is subjected to vibration or bumps, the BC cell 400 can be firmly fixed in the cell receiving groove 200, avoiding friction or impact between the BC cell 400 and the electromagnetic cell receiving groove during the shaking process, which would cause damage to the BC cell 400.

[0033] In an optional embodiment, the wire receiving groove 300 includes mating grooves located at both ends of the wire receiving groove 300, the mating grooves being located at the bottom of the battery cell receiving groove 200, and two mating grooves in the same wire receiving groove 300 being connected by a connecting groove.

[0034] The mating groove is located at the bottom of the cell receiving groove 200, which facilitates the connection of the conductive grid lines on the back of the BC cell 400 with the wires 500.

[0035] In an optional embodiment, the shape and size of the mating groove are adapted to the diameter of the conductive grid lines on the back of the BC cell 400.

[0036] The conductive grid lines on the back of the BC cell 400 are connected to other BC cells 400 through the wires 500 in the wire receiving groove 300. The groove is adapted to the shape and size of the wires 500, which is conducive to the wires 500 making full contact with the conductive grid lines.

[0037] In an optional embodiment, the back panel 100 of the color steel sheet is provided with an insulating layer on the side near the BC battery cell 400.

[0038] The insulation layer insulates the back panel 100 of the color steel tile from the BC battery cell 400.

[0039] In an optional embodiment, the insulating layer is a silicon oxide film or an aluminum oxide film.

[0040] In an optional embodiment, the conductor 500 is a tin-plated copper wire or a tin-plated silver wire.

[0041] In an optional embodiment, the BIPV assembly further includes two lead wires 800, and two lead wire receiving slots are correspondingly provided on the color steel tile back plate 100. One of the lead wires 800 is connected to the positive electrode 420 of the battery cell, and the other lead wire 800 is connected to the negative electrode 410 of the battery cell.

[0042] The lead wire 800 allows different BIPV color steel tile components to be interconnected, or allows BIPV color steel tile components to be connected to power collection devices, power storage devices or power utilization devices, facilitating the collection, storage and utilization of power.

The length and width of the BC cell 400 receiving groove 200 must meet the actual length and width of the BC cell 400 so that the BC cell 400 can be placed in the cell receiving groove 200. The depth of the cell receiving groove 200 is consistent with the thickness of the BC cell 400. After the BC cell 400 is placed in the cell receiving groove 200, the surface of the BC cell 400 is coplanar with the surface of the color steel tile. Step (2): A wire receiving groove 300 is created. The wire receiving groove 300 is formed on the color steel tile substrate after the cell receiving groove 200 has been processed. A milling machine is used to create the groove according to the designed shape. The depth of the wire receiving groove 300 is consistent with the diameter of the conductive grid lines on the back of the BC cell 400, so that the wire 500 is perfectly embedded in the groove. A schematic diagram of the structure of the color steel tile backplate 100 with the cell receiving groove 200 and the wire receiving groove 300 is shown below. Figure 2 As shown; Step (3): Insulation treatment of the back panel 100 of the color steel tile: deposit a silicon oxide film, an aluminum oxide film or other insulating film on one side of the back panel 100 of the color steel tile with the cell receiving groove 200 and the wire receiving groove 300 to insulate the back panel from the battery panel. Step (4): Wiring. Wires 500 are arranged within the wire receiving groove 300. Wires 500 are tin-plated copper wire or tin-plated silver wire, etc. A schematic diagram of the wiring on one side of the battery cell receiving groove 200 on the color steel tile back panel 100 is shown below. Figure 3 As shown; Step (5): Cell arrangement. Place the BC cells into the cell receiving slot 200. The positive electrode 420 and negative electrode 410 of all cells are aligned. The positive and negative electrodes 410 of adjacent BC cells 400 are connected by wires 500. Assemble to obtain the BIPV module. The specific structure is as follows: Figure 4As shown in the diagram, the connection between the BC solar cell 400 and the wire 500 is as follows: Figure 5 As shown in the diagram, the structural schematic of the back side of the BC solar cell 400 is as follows: Figure 6 As shown; Step (6): Laying the 600 adhesive film. Lay the 600 adhesive film on the arranged BIPV components, such as... Figure 7 As shown, the 600 adhesive film needs to have properties such as corrosion resistance and oxidation resistance as the main encapsulation material; Step (7): The front glass 700 is laid on top of the adhesive film 600. After lamination, the BIPV module and the front glass 700 are bonded and sealed together to form a color steel tile module.
