Description

Technical Field

[0002] Perovskite solar cells, as a new generation of photovoltaic cells, are showing increasing efficiency and stability, making them a candidate for mainstream photovoltaic products in the future.

[0003] Currently, to facilitate the subsequent encapsulation process of applying adhesives and other materials to perovskite solar panels, it is necessary to remove the cell film layer around the edges of the solar panel to form a perimeter cleaning zone. This perimeter cleaning zone is then isolated from the central cell area to prevent external high voltage from damaging the central cell area, thus providing insulation. Existing methods for measuring the insulation impedance of the perimeter cleaning zone and the central cell area use probe-based sampling, which results in an inability to comprehensively and accurately obtain the insulation impedance of both areas, leading to product scrap.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0046] Figure 1 This is a structural schematic diagram of a perovskite solar cell module provided by related technologies, such as... Figure 1As shown, the formation process of a perovskite solar cell module mainly includes: forming a conductive glass 2 on one side of a glass substrate 1. The conductive glass 2 may include fluorine-doped tin oxide (FTO) conductive glass or indium-doped tin oxide (ITO) conductive glass. A first groove 21 is etched on the conductive glass 2. Then, a first buffer layer 3 is formed on the side of the conductive glass 2 away from the glass substrate 1. A perovskite layer 4 is formed on the side of the first buffer layer 3 away from the glass substrate 1. A second buffer layer 5 is formed on the side of the perovskite layer 4 away from the glass substrate 1. A second groove 31 is formed by etching the second buffer layer 5, the perovskite layer 4, and the first buffer layer 3. The second groove 31 can be located to the left or right of the first groove 21. Next, a top electrode 6 is formed on the side of the second buffer layer 5 away from the glass substrate 1. A third groove 41 is formed by etching the top electrode 6, the second buffer layer 5, the perovskite layer 4, and the first buffer layer 3. The second groove 31 is located between the first groove 21 and the third groove 41. Thus, the perovskite solar cell module becomes a series of interconnected cells.

[0047] Figure 2 This is a schematic diagram of the structure of a solar panel provided by related technologies. The solar panel 7 includes... Figure 1 The perovskite solar cell module shown is an example. Figure 1 and Figure 2 As shown, after the production is completed Figure 1 After each of the shown film layers, a certain width of perovskite film layer needs to be removed using a laser to form the perimeter cleaning area 72 of the solar panel 7. The manufacturing method of the perimeter cleaning area 72 is mainly laser processing, and its main function is to remove the battery film layer at the perimeter of the solar panel 7 to facilitate the subsequent encapsulation of the solar cell module. During the manufacturing process of the perimeter cleaning area 72, due to situations such as laser obstruction or laser malfunction, some conductive film layer may remain in the perimeter cleaning area 72. When there is a large amount of residue, the central battery area 71 and the perimeter cleaning area 72 will be in a conductive state. However, the probe point contact measurement method will miss points during the measurement process, resulting in the inability to fully and accurately obtain the insulation resistance of the perimeter cleaning area 72 and the central battery area 71. In this case, some modules fail the high-voltage test, resulting in product scrap and loss.

[0048] To solve the above problems, the technical solution of this utility model embodiment is as follows:

[0049] Figure 3 This is a schematic diagram of the structure of an insulation resistance measuring device for a solar panel provided in an embodiment of this utility model. Figure 4 This is a partial structural diagram of an insulation resistance measuring device for a solar panel provided in an embodiment of this utility model. Figure 5 This is a partial structural diagram of another solar panel insulation resistance measuring device provided in this embodiment of the present invention. Figure 6This is a top view of a conductive strip, a measuring head, and a solar panel in contact, as provided in an embodiment of this utility model. Figures 3-6 As shown, the solar panel 7 includes a perimeter clearing area 72 and a central battery area 71. An insulation impedance measuring device is used to measure the impedance values ​​of the perimeter clearing area 72 and the central battery area 71. The insulation impedance measuring device includes: a platform 10 for supporting the solar panel 7; a measuring head fixing module 20 fixedly connected to the platform 10; a cutout area 25; a conductive strip 22; and a measuring head 23. The conductive strip 22 is fixed to the side of the measuring head fixing module 20 near the platform 10. The measuring head 23 is disposed in the cutout area 25 and connected to the measuring head fixing module 20 via an elastic arm 24. The control module 30 is located on the side of the measuring head fixing module 20 away from the stage 10. The control module 30 is used to control the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 closer to the stage 10 by a first preset distance, so that the conductive strip 22 makes conductive contact with the surrounding edge cleaning area 72 and the measuring head 23 makes conductive contact with the central battery area 71.

[0050] Specifically, when it is necessary to measure the insulation resistance between the perimeter clearing area 72 and the central battery area 71 of the solar panel 7, the solar panel 7 can be placed on one side of the surface of the platform 10, which can support and fix the solar panel 7. The measuring head fixing module 20 may include multiple sub-modules. Figure 3 and Figure 5 The measuring head fixing module 20 shown only shows the outermost substructure of the measuring head fixing module 20. The remaining substructures of the measuring head fixing module 20 are located on the side of its outermost substructure close to the stage 10.

[0051] The measuring head fixing module 20 can be used to fix the conductive strip 22 and the measuring head 23. The conductive strip 22 is fixed to the side of the measuring head fixing module 20 near the stage 10. For example, the conductive strip 22 can be attached to the side of the measuring head fixing module 20 near the stage 10. The measuring head 23 can be fixed to the inner side of the measuring head fixing module 20 by means of the elastic arm 24. The stage 10 and the measuring head fixing module 20 can be fixedly connected by means of guide posts 40 and guide sleeves.

[0052] The shape of the conductive strip 22 can match the shape of the surrounding edge cleaning area 71, but the width of the conductive strip must be smaller than the width of the surrounding edge cleaning area 71. When measuring the insulation resistance between the surrounding edge cleaning area 72 and the central battery area 71 of the solar panel 7, the conductive strip 22 can make surface contact with the surrounding edge cleaning area 72, but a certain distance must be maintained between the conductive strip 22 and the central battery area 71 to avoid short-circuiting. The measuring head 23 can also make surface contact with the central battery area 71, and the area of ​​the side of the measuring head 23 closest to the stage 10 can be set according to requirements, without specific limitations here.

[0053] The control module 30 is located on the side of the measuring head fixing module 20 away from the stage 10. When it is necessary to measure the insulation impedance between the perimeter cleaning area 72 and the central battery area 71 of the solar panel 7, the control module 30 can use the first pressure to control the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 towards the stage 10 by a first preset distance, so as to ensure that the conductive strip 22 is in conductive contact with the perimeter cleaning area 72 and the measuring head 23 is in conductive contact with the central battery area 71.

[0054] The distance between the side of the conductive strip 22 near the stage 10 and the stage 10 can be equal to the distance between the side of the measuring head 23 near the stage 10 and the stage 10, or the distance between the side of the conductive strip 22 near the stage 10 and the stage 10 can be greater than the distance between the side of the measuring head 23 near the stage 10 and the stage 10. The first preset distance can be set to the distance between the side of the conductive strip 22 near the stage 10 and the stage 10, or the first preset distance can be set to be slightly greater than the distance between the side of the conductive strip 22 near the stage 10 and the stage 10. When the control module 30 controls the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 a first preset distance toward the platform 10, the conductive strip 22 and the measuring head 23 can simultaneously contact the solar panel 7. Alternatively, when the distance between the side of the conductive strip 22 and the platform 10 is greater than the distance between the side of the measuring head 23 and the platform 10, the measuring head 23 can first contact the central battery area 71, and the conductive strip 22 can then contact the surrounding edge cleaning area 72. However, since the measuring head 23 is connected to the measuring head fixing module 20 through the elastic arm 24, the measuring head 23 will not be damaged when the first preset distance the measuring head 23 moves toward the platform 10 is greater than the distance between the side of the measuring head 23 and the platform 10. This embodiment of the present invention effectively realizes that the control module 30 applies pressure once to make the conductive strip 22 make conductive contact with the surrounding edge cleaning area 72 and the measuring head 23 make conductive contact with the central battery area 71.

[0055] The technical solution of this utility model embodiment includes a solar panel insulation impedance measuring device comprising a conductive strip 22 and a measuring head 23. When measuring the insulation impedance between the perimeter clearing area 72 and the central battery area 71 of the solar panel 7, the conductive strip 22 can make surface contact with the perimeter clearing area 72, and the measuring head 23 can also make surface contact with the central battery area 71. This ensures that the insulation impedance measuring device does not miss any points when measuring the insulation impedance between the perimeter clearing area 72 and the central battery area 71 of the solar panel 7, and can comprehensively and accurately obtain the insulation impedance between the perimeter clearing area 72 and the central battery area 71, thereby improving the accuracy of the insulation impedance measurement between the perimeter clearing area 72 and the central battery area 71. When the insulation impedance between the perimeter clearing area 72 and the central battery area 71 does not meet the requirements, it can be 100% intercepted and reworked in a timely manner, avoiding the failure of some components in the high-voltage test and the resulting product scrap loss. At the same time, the control module 30 can apply pressure at once, so that the conductive strip 22 contacts the surrounding cleaning area 72 and the measuring head 23 contacts the central battery area 71, which effectively simplifies the measurement process of the insulation resistance between the surrounding cleaning area 72 and the central battery area 71.

[0056] Optionally, based on the above embodiments, continue to refer to... Figures 3-5 The insulation resistance measuring device for solar panels also includes at least one pressure module 50. The pressure module 50 is located on the side of the measuring head fixing module 20 away from the stage 10. The pressure module 50 is used to control the conductive strip 22 and the measuring head 23 to move a second preset distance toward the stage 10. The total distance that the conductive strip 22 and the measuring head 23 move toward the stage 10 is the sum of the first preset distance and the second preset distance.

[0057] Specifically, the insulation resistance measuring device for solar panels may further include at least one pressure module 50, which can be located on the side of the measuring head fixing module 20 away from the platform 10. After the control module 30 applies pressure to make the conductive strip 22 contact the surrounding edge cleaning area 72 and the measuring head 23 contact the central battery area 71, the pressure module 50 can further control the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 a second preset distance closer to the platform 10 using a second pressure. The pressure module 50 can press down the conductive strip 22 and the measuring head 23, ensuring that the conductive strip 22 makes full contact with the surrounding edge cleaning area 72 and the measuring head 23 makes full contact with the central battery area 71. The second preset distance can be set according to specific circumstances and is not specifically limited here.

[0058] Optionally, based on the above embodiments, continue to refer to... Figures 3-6The insulation impedance measuring device for the solar panel also includes an impedance measuring module (not shown in the figure). The impedance measuring module is connected to the conductive strip 22 and the measuring head 23. The impedance measuring module is used to measure the impedance between the conductive strip 22, which is in conductive contact with the surrounding edge cleaning area 72, and the measuring head 23, which is in conductive contact with the central battery area 71.

[0059] Specifically, the impedance measurement module is connected to the conductive strip 22 and the measuring head 23. When the conductive strip 22 is in contact with the surrounding cleaning area 72 and the measuring head 23 is in contact with the central battery area 71, the impedance measurement module can provide a DC voltage between the conductive strip 22 and the measuring head 23. For example, a DC voltage of 1000V-8000V can be provided. The impedance between the conductive strip 22 and the measuring head 23 is measured by reading the current between the conductive strip 22 and the measuring head 23, that is, the impedance between the surrounding cleaning area 72 and the central battery area 71 is measured.

[0060] Optionally, based on the above embodiments, continue to refer to... Figures 3-5 The distance between the side of the measuring head 23 near the platform 10 and the platform 10 is less than or equal to the distance between the side of the conductive strip 22 near the platform 10 and the platform 10.

[0061] Specifically, the distance between the side of the conductive strip 22 near the stage 10 and the stage 10 can be equal to the distance between the side of the measuring head 23 near the stage 10 and the stage 10, or the distance between the side of the conductive strip 22 near the stage 10 and the stage 10 can be greater than the distance between the side of the measuring head 23 near the stage 10 and the stage 10. The first preset distance can be set to the distance between the side of the conductive strip 22 near the stage 10 and the stage 10, or the first preset distance can be set to be slightly greater than the distance between the side of the conductive strip 22 near the stage 10 and the stage 10. When the control module 30 controls the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 a first preset distance toward the platform 10, the conductive strip 22 and the measuring head 23 can simultaneously contact the solar panel 7. Alternatively, when the distance between the side of the conductive strip 22 and the platform 10 is greater than the distance between the side of the measuring head 23 and the platform 10, the measuring head 23 can first contact the central battery area 71, and the conductive strip 22 can then contact the surrounding edge cleaning area 72. However, since the measuring head 23 is connected to the measuring head fixing module 20 through the elastic arm 24, the measuring head 23 will not be damaged when the first preset distance the measuring head 23 moves toward the platform 10 is greater than the distance between the side of the measuring head 23 and the platform 10. This embodiment of the utility model effectively realizes that the control module 30 applies pressure once to make the conductive strip 22 contact the surrounding edge cleaning area 72 and the measuring head 23 contact the central battery area 71.

[0062] Optionally, based on the above embodiments, Figure 7 This is a schematic diagram of the structure of a platform provided in an embodiment of this utility model, as shown below. Figures 3-7 As shown, the stage 10 includes an adsorption hole array 11, a positioning frame 12, and a first positioning hole 13. The adsorption hole array 11 is arranged in the central region of the stage 10, and the positioning frame 12 is located at the four corners of the adsorption hole array 11. The stage 10 also includes a vacuum adsorption channel, which communicates with the adsorption hole array 11 and is connected to an external vacuum pumping device. The vacuum pumping device vacuum adsorbs the solar panel 7 through the vacuum adsorption channel and the adsorption hole array 11. The positioning frame 12 is used to fix the solar panel 7. Along the width direction of the stage 10, the first positioning hole 13 is located on both sides of the adsorption hole array 11, and the guide post 40 is inserted into the first positioning hole 13 to fix the stage 10 and the measuring head fixing module 20.

[0063] Specifically, the central area of ​​the stage 10 can be arranged with an adsorption hole array 11, and a vacuum adsorption channel (not shown in the figure) can be provided inside the stage 10. The vacuum adsorption channel can be connected to a vacuum pumping device, which can include a vacuum pump or similar device. The positioning frame 12 is located at the four corners of the adsorption hole array 11, and the area enclosed by the positioning frame 12 can be the same as the area of ​​the solar panel 7, which can fix the solar panel 7. When it is necessary to measure the insulation resistance between the perimeter clearing area 72 and the central battery area 71 of the solar panel 7, the solar panel 7 can be placed in the area enclosed by the positioning frame 12, and the vacuum pumping device adsorbs the solar panel 7 by vacuuming.

[0064] The platform 10 is also provided with first positioning holes 13 on both sides, and the guide post 40 can be inserted into the first positioning holes 13 to fix the platform 10 and the measuring head fixing module 20.

[0065] Optionally, based on the above embodiments, Figure 8 This is a partial structural diagram of another solar panel insulation resistance measuring device provided in this embodiment of the present invention. Figure 9 This is a partial structural diagram of an insulation resistance measuring device for a solar panel provided in another embodiment of the present invention, as shown below. Figures 3-9As shown, the measuring head fixing module 20 includes a soft rubber pressure head 26 and a measuring head fixing plate 27. The measuring head fixing plate 27 includes a hollow area 25 and a second positioning hole 28, which corresponds to the first positioning hole 13. The guide post 40 is fixedly connected to the platform 10 and the measuring head fixing module 20 by being inserted into the first positioning hole 13 and the second positioning hole 28 respectively. The soft rubber pressure head 26 is fixed to the side of the measuring head fixing plate 27 near the platform 10, and the conductive material strip 22 is fixed to the side of the soft rubber pressure head 26 near the platform 10. The measuring head 23 is connected to the inner side of the measuring head fixing plate 27 through an elastic arm 24.

[0066] Specifically, the measuring head fixing module 20 may include a soft rubber pressure head 26 and a measuring head fixing plate 27. The soft rubber pressure head 26 can be fixed to the side of the measuring head fixing plate 27 near the stage 10, and avoids the setting area of ​​the second positioning hole 28. The hollow area 25 of the measuring head fixing plate 27 is the hollow area 25 of the measuring head fixing module 20.

[0067] Optionally, based on the above embodiments, Figure 10 This is a partial structural diagram of an insulation resistance measuring device for a solar panel provided in another embodiment of the present invention, as shown below. Figures 3-10 As shown, the insulation resistance measuring device for solar panels further includes a fixing plate 60, which may include a pressure module 50. The fixing plate 60 is located in the central region of the side of the measuring head fixing module 20 away from the stage 10, and covers the hollow area 25. The control module 30 is located on the side of the fixing plate 60 away from the stage 10, and the pressure module 50 is located on the side of the fixing plate 60 away from the stage.

[0068] Specifically, when it is necessary to measure the insulation resistance between the perimeter cleaning area 72 and the central battery area 71 of the solar panel 7, the control module 30 can move the fixing plate 60 by controlling the first pressure, so that the measuring head fixing module 20 drives the conductive strip 22 and the measuring head 23 to move a first preset distance closer to the platform 10, ensuring that the conductive strip 22 contacts the perimeter cleaning area 72 and the measuring head 23 contacts the central battery area 71. This embodiment of the invention effectively achieves the control module 30 applying pressure once to make the conductive strip 22 contact the perimeter cleaning area 72 and the measuring head 23 contact the central battery area 71. Then, the pressurizing module 50 can move the fixing plate 60 further by controlling the second pressure, so that the measuring head fixing module 20 drives the conductive strip 22 and the measuring head 23 to move a second preset distance closer to the platform 10. The pressurizing module 50 can press down the conductive strip 22 and the measuring head 23, so that the conductive strip 22 fully contacts the perimeter cleaning area 72 and the measuring head 23 fully contacts the central battery area 71.

[0069] Figure 11This is a schematic diagram of the structure of another insulation resistance measuring device for solar panels provided in this utility model embodiment, as shown below. Figures 4-5 , Figure 11 As shown, the insulation resistance measuring device also includes a first fixing plate 61 and a second fixing plate 62, and the insulation resistance measuring device includes multiple pressure modules 50. The first fixing plate 61 is located in the central area of ​​the side of the measuring head fixing module 20 away from the stage 10, and the first fixing plate 61 covers the hollow area 25. The multiple pressure modules 50 are located at the edge of the side of the first fixing plate 61 away from the stage 10. The second fixing plate 62 is located on the side of the pressure modules 50 away from the stage 10, and the control module 30 is located on the side of the second fixing plate 62 away from the stage 10.

[0070] Specifically, Figure 11 The measuring head fixing module 20 shown only shows the outermost substructure of the measuring head fixing module 20. The remaining substructures of the measuring head fixing module 20 are located on the side of its outermost substructure close to the stage 10.

[0071] When it is necessary to measure the insulation resistance between the perimeter cleaning area 72 and the central battery area 71 of the solar panel 7, the control module 30 can control the movement of the first fixing plate 61, the pressure module 50, and the second fixing plate 62 by applying a first pressure. At this time, the pressure module 50 does not work, causing the measuring head fixing module 20 to move the conductive strip 22 and the measuring head 23 a first preset distance toward the platform 10, ensuring that the conductive strip 22 contacts the perimeter cleaning area 72 and the measuring head 23 contacts the central battery area 71. This embodiment of the invention effectively achieves the goal of the control module 30 applying pressure once to make the conductive strip 22 contact the perimeter cleaning area 72 and the measuring head 23 contact the central battery area 71. Next, the pressurizing module 50 can control the movement of the second fixing plate 61 by the second pressure, so that the measuring head fixing module 20 drives the conductive strip 22 and the measuring head 23 to move a second preset distance closer to the platform 10. The pressurizing module 50 can press down the conductive strip 22 and the measuring head 23, so that the conductive strip 22 is in full contact with the surrounding edge cleaning area 72, and the measuring head 23 is in full contact with the central battery area 71.

[0072] Optionally, based on the above embodiments, continue to refer to... Figures 3-11 The pressurization module 50 includes a pressurization cylinder 51, a piston (not shown), and a piston rod 52. The piston is located inside the pressurization cylinder 51, one end of the piston rod 52 is connected to the piston, and the other end of the piston rod 52 extends towards the measuring head fixing module 20. The pressurization cylinder 51 is used to introduce high-pressure gas, the piston is used to move towards the measuring head fixing module 20 under the pressure of the high-pressure gas, and the piston rod 52 is used to continue extending towards the measuring head fixing module 20 as the piston moves towards the measuring head fixing module 20.

[0073] Specifically, the pressurizing module 50 may include a pressurizing cylinder 51, a piston (not shown in the figure), and a piston rod 52. After the control module 30 applies pressure to make the conductive material strip 22 contact the surrounding cleaning area 72 and the measuring head 23 contact the central battery area 71, the pressurizing cylinder 51 introduces high-pressure gas. Under the pressure of the high-pressure gas, the piston moves towards the measuring head fixing module 20. As the piston moves towards the measuring head fixing module 20, the piston rod 52 continues to extend towards the measuring head fixing module 20. Further control of the measuring head fixing module 20 causes the conductive material strip 22 and the surface-contact measuring head 23 to move a second preset distance towards the stage 10, ensuring full contact between the conductive material strip 22 and the surrounding cleaning area 72, and full contact between the measuring head 23 and the central battery area 71.

[0074] Optionally, based on the above embodiments, continue to refer to... Figures 3-11 The conductive strip 22 matches the shape of the surrounding cleaning area 72, and the side of the measuring head 23 closest to the stage 10 has a surface structure.

[0075] Specifically, the shape of the conductive strip 22 can match the shape of the surrounding edge cleaning area 71, but the width of the conductive strip must be smaller than the width of the surrounding edge cleaning area 71. When measuring the insulation resistance between the surrounding edge cleaning area 72 and the central battery area 71 of the solar panel 7, the conductive strip 22 can make surface contact with the surrounding edge cleaning area 72, but a certain distance must be maintained between the conductive strip 22 and the central battery area 71 to avoid short-circuiting. The measuring head 23 can also make surface contact with the central battery area 71, and the area of ​​the side of the measuring head 23 closest to the stage 10 can be set according to requirements, without specific limitations here.
