[0002] Perovskite solar cells offer advantages such as high efficiency, low cost, and flexibility, making them widely applicable in various flexible scenarios, including wearable devices and portable outdoor power banks. In the actual fabrication process of foldable perovskite solar cells, a rigid-to-flexible conversion process is typically employed. This involves attaching a flexible substrate to a rigid substrate (such as glass), then depositing various functional layers on the flexible substrate to create the complete cell structure. After fabrication, the cell structure is encapsulated, and finally, the rigid and flexible substrates are separated.

Each component is then sequentially encapsulated, and external wires are used to connect them in series. Finally, the rigid and flexible substrates are separated.

[0033] This invention provides a method for fabricating a foldable perovskite module. When fabricating the perovskite module, a rigid-flexible conversion process is employed. The battery structure is fabricated on a rigid substrate. Then, according to the perovskite module design, an edge-cleaning device is used to clean the battery material in multiple folding areas (i.e., areas where the perovskite module needs to be bent during folding), exposing the flexible substrate within these folding areas. These multiple folding areas divide the battery structure into multiple battery components. The edge-cleaning device is then used to clean the battery material at the edges of the battery components, ensuring that the actual dimensions of the battery components match the preset dimensions. Finally, a first connecting component is placed on one side of the positive electrode of the battery component, and on the other side... A second connecting component is then installed so that the positive electrodes of multiple battery components are connected in series sequentially by the first connecting component, and the negative electrodes of multiple battery components are connected in series sequentially by the second connecting component. Then, a sealing element is set along the circumferential direction on the edge area of ​​the battery component, so that the sealing element forms a shielding ring. The shielding ring can shield the first connecting component and the second connecting component. The cover is stacked on the shielding ring, and the cover and the sealing element are pressed together using a pressing device, so that the cover and the sealing element are pressed together as one unit, that is, the cover and the battery component are combined. Finally, the rigid substrate is separated from the flexible substrate of the battery structure. When the battery structure needs to be folded, only the flexible substrate within the exposed folding area needs to be bent.

[0034] Using the above-described preparation method to fabricate perovskite modules eliminates the need to split the obtained battery structure into multiple battery components, encapsulate each component separately, and connect them in series with external wires. Instead, the battery components are connected in series by setting a first connecting component and a second connecting component, and then encapsulated uniformly. That is, by setting a sealing element to shield the first and second connecting components, the preparation steps of the encapsulation process can be reduced, the manufacturing process can be simplified, the workload can be reduced, and the work efficiency can be improved. In addition, the use of a sealing element to shield the first and second connecting components, i.e., placing the first and second connecting components inside the battery structure, can provide protection for the first and second connecting components, preventing them from being damaged by repeated bending and ensuring the normal use of the battery structure.

[0046] This embodiment provides a method for preparing a foldable perovskite component, such as... Figure 1 and Figure 2 As shown, using this method to prepare perovskite components can simplify the manufacturing process, reduce preparation steps, reduce labor, and improve work efficiency.

[0047] like Figure 1 As shown, the fabrication method of the foldable perovskite component includes the following steps:

[0048] S1. A battery structure 1 is fabricated on a rigid substrate. The battery structure 1 includes a flexible substrate 12 and a battery material deposited on the flexible substrate 12. The flexible substrate 12 is attached to the rigid substrate.

[0049] S2. According to the design scheme of the perovskite module, control the edge cleaning equipment to clean the battery material in multiple folded areas 11 of the battery structure 1, so as to expose the flexible substrate 12 in the folded areas 11. The multiple folded areas 11 divide the battery structure 1 into multiple battery components 13.

[0050] S3. Control the edge cleaning device to clean the battery material in the edge area of ​​the battery component 13 to obtain the battery component 13 of a preset size;

[0051] S4. A first connecting component 2 is provided on the positive electrode side of the multiple battery components 13, the first connecting component 2 can connect the positive electrodes of the multiple battery components 13 in series, and a second connecting component 3 is provided on the negative electrode side of the multiple battery components 13, the second connecting component 3 can connect the negative electrodes of the multiple battery components 13 in series.

[0052] S5. A sealing element 4 is provided circumferentially in the edge area of ​​the battery component 13 so that the sealing element 4 forms a shielding ring, and the shielding ring can shield the first connecting component 2 and the second connecting component 3.

[0053] S6. Place the cover on the shielding ring;

[0054] S7. Control the crimping equipment to crimp the cover and the seal 4 so that the cover and the seal 4 are crimped together as one unit;

[0055] S8, Flexible substrate 12 separating the rigid substrate from the battery structure 1.

[0056] When fabricating perovskite modules, a rigid-flexible conversion process is employed. Battery structure 1 is fabricated on a rigid substrate. Then, according to the perovskite module design, an edge-cleaning device is used to clean the battery material in multiple folded regions 11 (i.e., areas where the perovskite module needs to be bent during folding) of battery structure 1, exposing the flexible substrate 12 within the folded regions 11. The multiple folded regions 11 divide battery structure 1 into multiple battery components 13. The edge-cleaning device is then used to clean the battery material at the edges of battery components 13, ensuring that the actual size of battery components 13 matches the preset size. Finally, a first connecting component 2 is placed on one side of the positive electrode of battery component 13, and a second connecting component 3 is placed on the other side of the negative electrode, so that... The first connecting component 2 connects the positive electrodes of multiple battery components 13 in series, and the second connecting component 3 connects the negative electrodes of multiple battery components 13 in series. Then, a sealing element 4 is set along the circumferential direction on the edge area of ​​the battery component 13, so that the sealing element 4 forms a shielding ring. The shielding ring can shield the first connecting component 2 and the second connecting component 3. The cover is stacked on the shielding ring, and the cover and the sealing element 4 are pressed together using a pressing device, so that the cover and the sealing element 4 are pressed together into one piece, that is, the cover and the battery component 13 are combined. Finally, the rigid substrate is separated from the flexible substrate 12 of the battery structure 1. When it is necessary to fold the battery structure 1, it is only necessary to bend the flexible substrate 12 within the exposed folding area 11.

[0057] Using the above preparation method to prepare perovskite modules, it is not necessary to split the prepared battery structure 1 into multiple battery components 13, encapsulate each battery component 13 separately, and connect them in series with external wires. Instead, the battery components 13 are connected in series by setting the first connecting component 2 and the second connecting component 3 and then encapsulated uniformly. That is, by setting the sealing component 4 to shield the first connecting component 2 and the second connecting component 3, the preparation steps of the encapsulation process can be reduced, the manufacturing process can be simplified, the amount of labor can be reduced, and the work efficiency can be improved. In addition, the preparation method uses the sealing component 4 to shield the first connecting component 2 and the second connecting component 3, that is, to set the first connecting component 2 and the second connecting component 3 inside the battery structure 1, which can provide protection for the first connecting component 2 and the second connecting component 3, prevent them from being damaged by repeated bending, and ensure the normal use of the battery structure 1.

[0058] It should be noted that the battery structure 1 includes a flexible substrate 12 and battery material stacked on the flexible substrate 12, with the flexible substrate 12 attached to a rigid substrate.

[0059] For example, the rigid substrate includes glass, the edge cleaning equipment includes a laser edge cleaning machine, and the pressing equipment includes a laminator.

[0060] Optionally, such as Figure 2 As shown, the first connection assembly 2 includes a first connection guide 21 and a plurality of positive electrode guides 22, each corresponding to a positive electrode of a plurality of battery components 13. The second connection assembly 3 includes a second connection guide 31 and a plurality of negative electrode guides 32, each corresponding to a negative electrode of a plurality of battery components 13. Step S4 specifically includes the following steps:

[0061] S41. Control the edge cleaning device to clean the battery material in the first bonding area on the positive side of the battery component 13 and clean the battery material in the second bonding area on the negative side of the battery component 13, so that the flexible substrate 12 corresponding to the first bonding area and the flexible substrate 12 corresponding to the second bonding area are both exposed.

[0062] S42. A plurality of positive electrode guides 22 are attached one-to-one to the first attachment area of ​​a plurality of battery components 13, and the outer connection end of each positive electrode guide 22 extends to the edge area of ​​the positive electrode side of the corresponding battery component 13. The first connection guide 21 is connected in series with the outer connection ends of the plurality of positive electrode guides 22, and the first connection guide 21 is attached to the edge area of ​​the positive electrode side of the battery component 13, and the first connection guide 21 extends along the arrangement direction of the plurality of battery components 13.

[0063] S43. A plurality of negative electrode guides 32 are attached one-to-one to the second attachment area of ​​a plurality of battery components 13, and the outer connection end of each negative electrode guide 32 extends to the edge area of ​​the negative electrode side of the corresponding battery component 13. The second connection guide 31 is connected in series with the outer connection ends of the plurality of negative electrode guides 32, and the second connection guide 31 is attached to the edge area of ​​the negative electrode side of the battery component 13, and the second connection guide 31 extends along the arrangement direction of the plurality of battery components 13.

[0064] For example, the first connecting guide 21, the positive electrode guide 22, the second connecting guide 31, and the negative electrode guide 32 all include a drainage strip.

[0065] Optionally, such as Figure 2 As shown, the seal 4 includes a first sealing part 41, a second sealing part 42, a third sealing part 43, and a fourth sealing part 44. Step S5 specifically includes the following steps:

[0066] S51. A first sealing part 41 is provided in the edge region on the positive electrode side of the battery component 13, and the first sealing parts 41 of multiple battery components 13 are connected in sequence. A second sealing part 42 is provided in the edge region on the negative electrode side of the battery component 13, and the second sealing parts 42 of multiple battery components 13 are connected in sequence, so that the first sealing parts 41 of multiple battery components 13 cover the first connecting guide 21, and the second sealing parts 42 of multiple battery components 13 cover the second connecting guide 31.

[0067] S52. Along the width direction of the battery component 13, a third sealing part 43 and a fourth sealing part 44 are respectively provided in the edge areas on both sides of the plurality of battery components 13. The first sealing part 41, the second sealing part 42, the third sealing part 43 and the fourth sealing part 44 are arranged circumferentially in the edge areas of the battery component 13 and form a shielding ring. The shielding ring is used to shield the positive electrode guide 22 and the negative electrode guide 32.

[0068] It should be noted that each battery component 13 is provided with a shielding ring formed by the first sealing part 41, the second sealing part 42, the third sealing part 43 and the fourth sealing part 44. The positive electrode guide 22 and the negative electrode guide 32 of each battery component 13 are both enclosed inside the shielding ring. The outer connection end of the positive electrode guide 22 is stacked below the first sealing part 41, and the outer connection end of the negative electrode guide 32 is stacked below the second sealing part 42.

[0069] For example, the first sealing portion 41, the second sealing portion 42, the third sealing portion 43, and the fourth sealing portion 44 all include butyl rubber. When step S5 is performed, butyl rubber is applied along the circumference of the battery component 13 to form a shielding ring.

[0070] Optionally, the method for fabricating the foldable perovskite component further includes step S9. Step S9 specifically includes the following steps:

[0071] S9. A folded structure is provided on the flexible substrate 12 of the folded region 11.

[0072] When the battery structure 1 needs to be folded, the flexible substrate 12 within the exposed folding area 11 of the battery structure 1 can be bent along the folding structure. By setting the folding structure, the battery structure 1 can be more easily bent along the folding structure, thereby enabling the battery structure 1 to be folded neatly, making the overall structure more regular, and facilitating the storage and organization of the battery structure 1.

[0073] In this embodiment, the folding structure includes multiple folding openings, and the multiple folding openings are spaced apart along the length direction of the battery component 13.

[0074] In other embodiments, the creases and other structures can be configured as folding structures as needed, which is not limited here.

[0075] For example, the cover may include a glass backplate, a barrier film, or an encapsulating film; that is, the cover may be made of a rigid material or a flexible material.

[0076] Optionally, step S7 specifically includes the following steps:

[0077] S71. Adjust the processing parameters of the crimping equipment to the preset temperature and preset pressure values;

[0078] S72. Control the crimping equipment to press the cover and seal 4 vertically downwards at a preset temperature and pressure value, and maintain for a preset time, so that the cover and seal 4 are combined into one piece.

[0079] After the cover is stacked on the shielding ring, the processing parameters of the pressing equipment are adjusted to control the pressing equipment to press the cover and the seal 4 vertically downwards, thereby making the two bonded together and completing the encapsulation of the battery structure 1. By controlling the temperature and pressure values ​​of the pressing equipment, the pressing equipment can heat the seal 4, causing the seal 4 to bond with the cover, thus making the two bonded together. At the same time, it can prevent the temperature from being too high and affecting the bonding strength of the seal 4, and can also avoid the temperature from being too high and damaging the cover. The pressing equipment heats and presses at a preset pressure value and holds it for a preset time. Holding the pressure value can promote the bonding between the seal 4 and the cover, and can make the two fully bonded, forming a stable adhesive structure and ensuring the strength of the bond.

[0080] For example, the preset temperature is 80℃~130℃, the preset pressure is 20kPa~80kPa, and the preset time is 5min~20min.

[0081] In this embodiment, the preset temperature is 80°C, the preset pressure is 20 kPa, and the preset time is 20 min. In other embodiments, the preset temperature, preset pressure, and preset time can be set to other values ​​as needed, and this is not limited here.

[0082] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
