[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0036] Example 1

[0037] Reference Figure 1-5 As shown, the present invention provides a busbar electrical connection structure for a solar power generation module, comprising:

[0038] The main structure includes a first main body 1 and a second main body 3 that are stacked together.

[0039] The conductive mechanism 5 includes a conductive layer 53 disposed between the first body 1 and the second body 3. The conductive layer 53 is a flexible conductive layer with a thickness ranging from 0.02 mm to 0.03 mm.

[0040] The present invention discloses a busbar electrical connection structure for a solar power generation module. By placing a conductive layer 53 between a first main body 1 and a second main body 3, the conductive layer 53 satisfies both the electrical connection of the first main body 1 and the second main body 3 and the adhesion between them. The conductive layer 53 is filled into the gap between the first main body 1 and the second main body 3 by hot pressing, and after cooling and curing, it can form a stable physical connection between the first main body 1 and the second main body 3, thereby providing a considerable adhesive strength. Since the conductive layer 53 is a flexible conductive layer, it can be used for the connection of flexible photovoltaic modules. In the area where connection is required, the gap is compressed to a thickness range of 0.02mm-0.03mm, which not only reduces resistance, but also makes it easier for the conductive components in the conductive layer 53 to form a connection between the conductive parts of the first main body 1 and the second main body 3 during the compression process, realizing a reliable electrical connection between the first main body 1 and the second main body 3. Furthermore, due to its low thickness, its strain is smaller when folded or bent, which can further ensure the flexibility and bending performance of the conductive layer 53.

[0041] See Figures 2-4 As shown, the conductive layer 53 includes an insulating layer and a conductive filler. The conductive filler is composed of a large number of conductive balls 52. The insulating layer is filled between the first body 1 and the second body 3. The conductive filler is filled in the insulating layer, and the conductive balls 52 are filled in the insulating layer. Both the insulating layer and the conductive filler are made of materials of the prior art. This utility model does not make any improvements to the specific materials. When the conductive layer 53 is squeezed between the first body 1 and the second body 3, since the thickness of the conductive layer 53 is only 0.02mm-0.03mm, the conductive filler therein can easily form a conductive connection between the first body 1 and the second body 3.

[0042] See Figure 3 As shown, the insulating layer is a resin layer, the conductive filler is conductive microparticles, and the insulating layer material is resin, which can be epoxy resin. Epoxy resin has excellent insulation properties, heat resistance and chemical corrosion resistance, and the conductive channels composed of conductive microparticles provide the required conductivity.

[0043] See Figure 1 , Figure 3 , Figure 5 As shown, the first body 1 and the second body 3 are respectively provided with conductive strips at intervals. The conductive strips of the first body 1 and the second body 3 are arranged correspondingly. The conductive strips are the conductive bodies to be connected to the first body 1 and the second body 3. There are multiple of them and they correspond to each other one by one. The conductive channels formed by the arrangement enable the corresponding conductive bodies in the upper and lower directions to conduct through each other, while the adjacent conductive bodies in the horizontal direction are insulated from each other. The adjacent conductive bodies are separated by resin to form an insulating space 51, so as to realize unidirectional conduction and avoid mutual interference between the conductive bodies in the horizontal direction.

[0044] See Figure 5 As shown, the first body 1 is a connector for a perovskite solar power generation module, and the second body 3 is a busbar. The length direction of the second body 3 is perpendicular to the length direction of the first body 1, and multiple first bodies 1 can be electrically connected through the second body 3.

[0045] Example 2

[0046] See Figure 1-6 As shown, this embodiment discloses a crimping device 4, which includes a solar power generation module bus electrical connection structure as described in Embodiment 1.

[0047] The crimping device 4 includes:

[0048] Equipment body 401;

[0049] The pressing mechanism includes: a driving member 410 disposed on the device body 401, and a pressing head 404 connected to the output end 409 of the driving member 410;

[0050] The pressing base 402 is located in the movement path of the pressing head 404.

[0051] The main body 401 is the main part of the entire crimping equipment 4, including the control system, power supply, etc. The crimping mechanism is used to perform the crimping operation. The driving component 410 is used to provide power or driving force to drive the movement of the crimping mechanism. It can be a pneumatic cylinder, electric cylinder, or hydraulic cylinder. The pressing head 404 is used to apply pressure to complete the crimping operation. The guide sleeve 408 guides the movement of the pressing plate. The support body 406 is used to support the driving component 410. The crimping base 402 is used to support and position the solar power generation module or other components that need to be crimped. The first main body 1 and the second main body 3 are placed on the crimping base 402, and the driving component... 410 drives the pressure head 404 to press down. The conductive layer 53 is between the first body 1 and the second body 3. The initial thickness is 0.10mm. The conductive layer 53 is softened and flowed by heating, pressurizing and holding pressure, filling the gap between the two exposed conductive areas and providing a considerable adhesive force. In the area to be connected, the gap is compressed to a thickness of 0.02mm-0.03mm, realizing a reliable electrical connection of the conductive layer 53. After the above hot pressing, the area to be connected 2 cools down and has a considerable reliable electrical connection. Moreover, the resistance level of the connection meets the requirements, the connection strength is high, and it can pass the relevant trial and testing requirements.

[0052] See Figure 6As shown, in this embodiment, the thermal curing temperature of the conductive layer 53 is 140°C, and the heating process temperature is no more than 150°C. After curing, it has high temperature stability and the advantages of low thermal expansion and low moisture absorption. It has water and oxygen barrier properties. The conductive layer 53 does not release volatile solvents and small molecules under normal conditions and under heating and pressure, and will not cause degradation and attenuation of perovskite properties.

[0053] Please continue reading Figure 6 As shown, the pressing mechanism further includes: a first pressure plate 407 connected to the output end 409 of the drive member 410, a second pressure plate 405 disposed on one side of the first pressure plate 407, and a threaded rod that is threadedly engaged with the first pressure plate 407 and the second pressure plate 405 respectively. The pressure head 404 is disposed on the second pressure plate 405, and the second pressure plate 405 is disposed below the first pressure plate 407. The height of the second pressure plate 405 and the pressure head 404 can be adjusted by the threaded connection of the threaded rod.

[0054] The device body 401 is equipped with a control system, which monitors and controls the various components of the crimping device 4 to ensure the accuracy and consistency of the crimping operation. The control system includes sensors, feedback loops, and regulators to adjust parameters during the crimping process, such as temperature, pressure, time, and counting. It also provides start and emergency stop functions. The crimping base 402 is a heated base and is equipped with a scale 403. The crimping base 402 is configured as a heated base so that it can provide heating during the crimping operation to ensure that the required temperature conditions are met during the crimping operation.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
