Description

Technical Field

[0001] This utility model relates to the field of solar cell technology, specifically to a busbar insulating strip and a solar cell module. Background Technology

[0002] To efficiently transfer the electrical energy inside solar cell modules to external electrical devices, busbars are typically installed inside the solar cell modules to collect the current and then transmit it to the external devices. Currently, to ensure that the busbars are securely fixed inside the solar cell modules, double-sided tape is generally used to secure them to the cell film layer of the solar cell module.

[0003] However, since the shrinkage rate of the adhesive layer on the side of the double-sided tape facing the busbar is greater in low-temperature environments than that of the busbar in high-temperature environments, when the solar cell module is cooled or placed in a low-temperature environment after high-temperature lamination, the double-sided tape will exert a pulling force on the cell film layer, causing defects such as blistering and delamination in the cell film layer, which in turn affects the power generation of the solar cell module. Utility Model Content

[0004] In view of this, the present invention provides a busbar insulating strip and a solar cell module to solve the problems mentioned in the background art.

[0005] In a first aspect, this utility model provides a busbar insulation strip, comprising:

[0006] An insulating tape substrate has an adhesive surface and an unadhesive surface disposed opposite to each other, wherein at least a portion of the unadhesive surface of the insulating tape substrate is used for contact application to a covered object;

[0007] A fixing structure is provided on the non-bonding surface of the insulating tape substrate and is used to fix it to the bearing surface;

[0008] The busbar is fixedly disposed on the bonding surface of the insulating tape substrate.

[0009] Beneficial effects: This invention involves direct contact between the non-adhesive surface of the insulating tape substrate and the covered body (i.e., the battery film layer in the solar cell module). This means there is no adhesive between the insulating tape substrate and the battery film layer. Therefore, in low-temperature environments, the insulating tape substrate will not exert a pulling force on the battery film layer, thus avoiding problems such as blistering and delamination of the battery film layer. Secondly, since there is no adhesive between the insulating tape substrate and the battery film layer, a fixing structure can be set on the non-adhesive surface of the insulating tape substrate to fix its position and prevent it from shifting due to vibration or external impact, ensuring that the insulating tape substrate remains in the preset position during subsequent use. Furthermore, since the busbar itself is non-adhesive, connecting the adhesive surface of the insulating tape substrate to the busbar can effectively prevent the busbar from moving arbitrarily and ensure its relative positional stability.

[0010] In one optional embodiment, the non-adhesive surface of the insulating tape substrate includes adjacent contact areas and fixing areas in its width direction, at least the contact areas are non-adhesive surfaces for contact covering the covered body, and the fixing structure is disposed within the fixing area.

[0011] Beneficial effects: This invention divides the non-bonding surface of the insulating tape substrate into a contact area and a fixing area, which allows operators to quickly determine the installation position of the non-bonding surface of the insulating tape substrate, improving assembly efficiency. Secondly, placing the fixing structure within the fixing area ensures that the fixing structure is spaced apart from the covered object, avoiding damage to the covered object caused by direct contact between the fixing structure and the covered object.

[0012] In one optional embodiment, there are multiple fixing structures, which are spaced apart along the length of the insulating tape substrate; or, the length of the fixing structure is adapted to the length of the insulating tape substrate.

[0013] Beneficial effects: By setting multiple fixing structures, this utility model increases the connection points between the insulating tape substrate and the bearing surface, making the position of the insulating tape substrate more stable and preventing it from shifting due to vibration or external impact. Similarly, ensuring that the length of the fixing structure matches the length of the insulating tape substrate allows for more sufficient contact between the two, guaranteeing relative positional stability.

[0014] In one optional embodiment, the fixing structure is a double-sided fixing tape; or, the fixing structure is an adhesive layer; or, the fixing structure is a fixing adhesive dot, with at least one fixing adhesive dot provided along the length direction of the insulating tape substrate.

[0015] Beneficial effects: When double-sided adhesive tape is used for fixing the structure, it has excellent adhesive properties, enabling quick and easy secure connection between the insulating tape substrate and the bearing surface. The flatness of the double-sided adhesive tape also helps ensure the stability of the connection. Furthermore, using double-sided adhesive tape to fix the insulating tape substrate simplifies the installation process, effectively improving assembly efficiency. If the fixing structure is an adhesive layer, the adhesive layer can evenly cover the non-adhesive surface of the insulating tape substrate, providing a large area of ​​adhesion and enhancing the stability of the insulating tape substrate's position. Using adhesive dots to fix the position of the insulating tape substrate not only ensures the relative stability of the insulating tape substrate and the bearing surface but also reduces operational difficulty, improves assembly efficiency, and lowers production costs.

[0016] In one alternative embodiment, at least a portion of the bonding surface of the insulating tape substrate is coated with a fixing adhesive that connects the insulating tape substrate and the busbar.

[0017] Beneficial effects: The application of fixing adhesive is relatively flexible and easy to operate, enabling effective connection between insulating tape substrates and busbars of different shapes and sizes, adapting to diverse design and manufacturing needs. At the same time, this connection method can simplify the assembly process to some extent, improve production efficiency, and reduce production costs.

[0018] In one alternative embodiment, the fixing adhesive is located within the orthographic projection area of ​​the busbar in the thickness direction of the insulating tape substrate.

[0019] Beneficial effects: This utility model ensures that the orthogonal projection of the fixing adhesive onto the busbar falls into the busbar, which can effectively connect and fix the bonding surface between the busbar and the insulating tape substrate while controlling the volume of the fixing adhesive within a reasonable range, thus avoiding excessive space occupation.

[0020] In one alternative embodiment, the bus insulation tape includes at least one of the following features:

[0021] The distribution direction or length direction of the fixed structure is consistent with the length direction of the insulating tape substrate;

[0022] Along the thickness direction of the insulating tape substrate, the orthogonal projection of the fixing structure toward the insulating tape substrate falls into the insulating tape substrate;

[0023] In the thickness direction of the insulating tape substrate, the orthographic projection area of ​​the fixing structure and the orthographic projection area of ​​the busbar are spaced apart;

[0024] The insulating tape substrate is integrally formed with the fixing structure.

[0025] Beneficial effects: This invention aligns the distribution direction or length direction of the fixing structure with the length direction of the insulating tape substrate, increasing the contact area between the fixing structure and the insulating tape substrate and ensuring the bonding effect of the fixing structure. Furthermore, ensuring that the orthographic projection of the fixing structure onto the insulating tape substrate falls within the insulating tape substrate keeps the volume of the fixing structure within a reasonable range, preventing excessive space occupation. Secondly, in the thickness direction of the insulating tape substrate, the orthographic projection area of ​​the fixing structure and the orthographic projection area of ​​the busbar are spaced apart, meaning there is a gap between the fixing structure and the covered object, thus preventing the fixing structure from interfering with the structure of the covered object. Moreover, the one-piece molding eliminates splicing gaps or weak points between the insulating adhesive layer and the fixing structure, forming a unified whole and enhancing the structural stability and reliability of the busbar insulation tape.

[0026] Secondly, this utility model also provides a solar cell module, comprising:

[0027] The front glass panel is provided with a battery cell film layer, and the front glass panel includes a clear edge area surrounding the battery cell film layer.

[0028] The aforementioned bus insulation tape has a portion of its non-adhesive surface attached to the battery cell film layer and another portion extending to the edge cleaning area, with the fixing structure located on the edge cleaning area;

[0029] The back glass is disposed opposite to the front glass and located on the side of the cell film layer away from the front glass;

[0030] An edge seal is disposed on the edge clearing area and surrounds the periphery of the cell film layer, and the edge seal connects the front glass and the back glass.

[0031] Beneficial effects: Part of the insulating tape substrate is attached to the cell film layer, while another part extends to the edge cleaning area to cooperate with the fixing structure. This not only effectively fixes the position of the insulating tape substrate inside the solar cell module, but also avoids the presence of adhesive between the insulating tape substrate and the cell film layer. This prevents the thermal shrinkage of the encapsulation film after encapsulation from pulling on the cell film layer, reducing the risk of the cell film layer being pulled off. Furthermore, by setting an edge seal, not only can the front and back glass be connected together to form a single unit for the solar cell module, but it can also cooperate with the front and back glass to create a sealed edge space for the cell film layer. This effectively prevents external moisture, dust, and other impurities from entering the solar cell module, thereby improving the waterproof and dustproof performance of the solar cell module and extending its service life.

[0032] In one alternative embodiment, the fixing structure is located between the edge seal and the cell film layer.

[0033] Beneficial effects: Since the edge seal is connected to the front and back glass, the present invention sets the fixing structure between the edge seal and the battery cell film layer, which can isolate the fixing structure from the external environment by using the edge seal, reducing the impact of external moisture, impurities and other factors on the fixing structure.

[0034] In one alternative embodiment, the fixing structure is at least spaced from the contour edge of the cell film layer.

[0035] Beneficial effects: This utility model sets the fixing structure and the cell film layer apart, which can avoid the fixing structure from interfering with the structure of the cell film layer and ensure the integrity of the cell film layer itself. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0046] According to embodiments of the present invention, on the one hand, such as Figure 2 and Figure 4 As shown, a busbar insulating tape is provided, including: an insulating tape substrate 1, a fixing structure 2, and a busbar 3.

[0047] Specifically, the insulating tape substrate 1 has an adhesive surface 101 and a non-adhesive surface 102 disposed opposite to each other, and at least part of the non-adhesive surface 102 of the insulating tape substrate 1 is used to contact and cover the covered body; the fixing structure 2 is disposed on the non-adhesive surface 102 of the insulating tape substrate 1 and is used to fix it on the bearing surface; the busbar 3 is fixedly disposed on the adhesive surface 101 of the insulating tape substrate 1.

[0048] In this embodiment of the invention, the non-adhesive surface 102 of the insulating tape substrate 1 is in direct contact with the covered body (i.e., the battery film layer in the solar cell module). This means that there is no adhesive between the insulating tape substrate 1 and the battery film layer. Therefore, in low-temperature environments, the insulating tape substrate 1 will not exert a pulling force on the battery film layer 5, thereby avoiding problems such as blistering and delamination of the battery film layer 5. Secondly, since there is no adhesive between the insulating tape substrate 1 and the battery film layer 5, a fixing structure 2 is provided on the non-adhesive surface 102 of the insulating tape substrate 1 to fix the position of the insulating tape substrate 1 and prevent it from shifting due to vibration or external impact, so as to keep the insulating tape substrate 1 in the preset position during subsequent use. Furthermore, since the busbar 3 itself is non-adhesive, connecting the adhesive surface 101 of the insulating tape substrate 1 to the busbar 3 can effectively prevent the busbar 3 from moving arbitrarily and ensure its relative positional stability.

[0049] It should be noted that the bonding surface 101 in this embodiment does not refer to the adhesive layer on one side of the insulating tape substrate 1. The adhesive layer can be the adhesive layer on the busbar 3 or an additional adhesive applied for bonding the busbar 3. The bonding surface 101 here refers only to the surface of the insulating tape substrate 1 used for bonding and fixing with the busbar 3.

[0050] According to one embodiment of the present invention, such as Figure 5As shown, the non-adhesive surface 102 of the insulating tape substrate 1 includes adjacent contact areas 1021 and fixing areas 1022 in its width direction. At least the contact area 1021 is a non-adhesive surface 102, used for contact covering onto the covered object. The fixing structure 2 is disposed within the fixing area 1022. This embodiment of the invention divides the non-adhesive surface 102 of the insulating tape substrate 1 into contact areas 1021 and fixing areas 1022, which allows operators to quickly determine the installation position of the non-adhesive surface 102 of the insulating tape substrate 1, improving assembly efficiency. Furthermore, by placing the fixing structure 2 within the fixing area 1022, the fixing structure 2 is spaced apart from the covered object, avoiding damage to the covered object caused by direct contact between the fixing structure 2 and the covered object. The non-adhesive surface 102 of the insulating tape substrate 1 is divided into two areas: the contact area 1021, used to isolate the cell film layer 5 from the backsheet glass 6 or encapsulating film of the solar cell module; and the insulating tape substrate 1, which is relatively fixed to the carrier by the fixing structure 2 in the fixing area 1022. It should be noted that the carrier is the edge clearing area 401 of the front glass 4 of the solar cell module.

[0051] According to one embodiment of this utility model, there are multiple fixing structures 2, which are spaced apart along the length of the insulating tape substrate 1; or, the length of the fixing structure 2 is adapted to the length of the insulating tape substrate 1. By providing multiple fixing structures 2, this embodiment of the utility model increases the number of connection points between the insulating tape substrate 1 and the bearing surface, making the position of the insulating tape substrate 1 more stable and preventing it from shifting due to vibration or external impact. Similarly, keeping the length of the fixing structure 2 adapted to the length of the insulating tape substrate 1 allows for more sufficient contact between the two, ensuring relative positional stability.

[0052] According to one embodiment of this utility model, the fixing structure 2 is a double-sided fixing tape; or, the fixing structure 2 is an adhesive layer; or, the fixing structure 2 is a fixing adhesive dot, with at least one fixing adhesive dot provided along the length direction of the insulating tape substrate 1. When the fixing structure 2 uses double-sided fixing tape, it has good adhesive performance, enabling quick and convenient firm connection between the insulating tape substrate 1 and the bearing surface, and the flatness of the double-sided fixing tape helps ensure the stability of the connection. Simultaneously, using double-sided fixing tape to fix the insulating tape substrate 1 simplifies the installation process, thereby effectively improving assembly efficiency. If the fixing structure 2 is an adhesive layer, the adhesive layer can uniformly cover the non-adhesive surface 102 of the insulating tape substrate 1, thereby providing a large area of ​​adhesive force and enhancing the stability of the insulating tape substrate 1's position. Using fixing adhesive dots to fix the position of the insulating tape substrate 1 not only ensures the relative stability of the position between the insulating tape substrate 1 and the bearing surface, but also reduces operational difficulty, improves assembly efficiency, and reduces production costs.

[0053] It should be noted that, in this embodiment, the material of the double-sided fixing tape is PET (polyethylene terephthalate) or TPU (thermoplastic polyurethane rubber); the material of the adhesive layer is one of single-layer acrylic adhesive, single-layer silicone, or butyl hot melt adhesive. The adhesive layer can be applied to the carrier or the insulating tape substrate 1 during application; no specific limitations are imposed here.

[0054] According to one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, at least a portion of the bonding surface 101 of the insulating tape substrate 1 is coated with a fixing adhesive, which connects the insulating tape substrate 1 and the busbar 3. It is understood that applying the fixing adhesive is a relatively flexible and easy-to-operate method, enabling effective connection between insulating tape substrates 1 and busbars 3 of different shapes and sizes, adapting to diverse design and manufacturing needs. Simultaneously, this connection method can simplify the assembly process to some extent, improve production efficiency, and reduce production costs.

[0055] According to one embodiment of the present invention, the fixing adhesive is located within the orthogonal projection area of ​​the busbar 3 in the thickness direction of the insulating tape substrate 1. This embodiment ensures that the orthogonal projection of the fixing adhesive toward the busbar 3 falls within the busbar 3, thereby effectively connecting and fixing the busbar 3 to the bonding surface 101 of the insulating tape substrate 1 while keeping the volume of the fixing adhesive within a reasonable range, thus avoiding excessive space occupation.

[0056] According to one embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the bus insulation tape includes at least one of the following features:

[0057] The distribution direction or length direction of the fixed structure 2 is consistent with the length direction of the insulating tape substrate 1;

[0058] Along the thickness direction of the insulating tape substrate 1, the orthographic projection of the fixing structure 2 toward the insulating tape substrate 1 falls into the insulating tape substrate 1;

[0059] In the thickness direction of the insulating tape substrate 1, the orthographic projection area of ​​the fixing structure 2 and the orthographic projection area of ​​the busbar 3 are spaced apart.

[0060] The insulating tape substrate 1 and the fixing structure 2 are integrally formed.

[0061] In this embodiment of the invention, the distribution direction or length direction of the fixing structure 2 is aligned with the length direction of the insulating tape substrate 1, which increases the contact area between the fixing structure 2 and the insulating tape substrate 1, ensuring the bonding effect of the fixing structure 2. Furthermore, by ensuring that the orthographic projection of the fixing structure 2 onto the insulating tape substrate 1 falls within the insulating tape substrate 1, the volume of the fixing structure 2 is kept within a reasonable range, avoiding excessive space occupation. Secondly, in the thickness direction of the insulating tape substrate 1, the orthographic projection area of ​​the fixing structure 2 and the orthographic projection area of ​​the busbar 3 are spaced apart, meaning that a gap is left between the fixing structure 2 and the covered object, thus preventing the fixing structure 2 from interfering with the structure of the covered object. Moreover, the integral molding ensures that there are no splicing gaps or weak points between the insulating adhesive layer and the fixing structure 2, forming a unified whole and enhancing the structural stability and reliability of the busbar insulation tape.

[0062] According to an embodiment of the present invention, on the other hand, as... Figure 1 and Figure 3 As shown, a solar cell module is also provided, including: a front glass panel 4, a cell film layer 5, the aforementioned busbar insulating strip, a back glass panel 6, and an edge seal 7.

[0063] Specifically, the front glass panel 4 is provided with a battery cell film layer 5, and the front glass panel 4 includes a cleaning area 401 surrounding the battery cell film layer 5; a portion of the non-adhesive surface 102 of the insulating tape substrate 1 is attached to the battery cell film layer 5, and another portion extends to the cleaning area 401, and the fixing structure 2 is located on the cleaning area 401; the back glass panel 6 is disposed opposite to the front glass panel 4 and is located on the side of the battery cell film layer 5 away from the front glass panel 4; the edge seal 7 is disposed on the cleaning area 401 and surrounds the battery cell film layer 5, and the edge seal 7 connects the front glass panel 4 and the back glass panel 6.

[0064] A portion of the insulating tape substrate 1 is attached to the cell film layer 5, while another portion extends to the edge cleaning area 401 to cooperate with the fixing structure 2. This not only effectively fixes the position of the insulating tape substrate 1 inside the solar cell module but also avoids the presence of adhesive between the insulating tape substrate 1 and the cell film layer 5. This prevents the thermal shrinkage of the encapsulating film after encapsulation from pulling on the cell film layer 5, reducing the risk of the cell film layer 5 being pulled off. Furthermore, by setting the edge seal 7, not only can the front panel glass 4 and the back panel glass 6 be connected together to form a single solar cell module, but it can also cooperate with the front panel glass 4 and the back panel glass 6 to form a sealing space for the cell film layer 5. This effectively prevents external moisture, dust, and other impurities from entering the interior of the solar cell module, thereby improving the waterproof and dustproof performance of the solar cell module and extending its service life.

[0065] It should be noted that the solar cell module in this embodiment can be a conventional perovskite solar cell structure, an inverted perovskite solar cell structure, or other thin-film solar cells, such as copper indium gallium selenide solar cells, cadmium telluride solar cells, and cadmium sulfide solar cells, etc. Specifically, when the solar cell module is a conventional perovskite solar cell structure, the cell film layer 5 includes a front electrode layer, an electron transport layer, a light absorption layer, a hole transport layer, and a back electrode layer stacked sequentially. The front electrode layer abuts against the front glass 4, and the back electrode layer is correspondingly disposed on one side of the back glass 6. When the perovskite solar cell module is an inverted perovskite solar cell structure, the cell film layer 5 includes a front electrode layer, a hole transport layer, a light absorption layer, an electron transport layer, and a back electrode layer stacked sequentially. The front electrode layer abuts against the front glass 4, and the back electrode layer is correspondingly disposed on one side of the back glass 6.

[0066] Furthermore, in an embodiment not shown, the edge seal 7 is butyl rubber. Using butyl rubber not only improves the overall stability of the solar cell encapsulation structure, but also allows the butyl rubber, front glass 4, and back glass 6 to form a sealed structure for the solar cell module. This prevents moisture and oxygen from the external environment from corroding or damaging the internal structure of the solar cell module, thereby effectively improving its stability and extending its lifespan.

[0067] It should be further noted that the insulating tape substrate 1 in this embodiment can be a strip-shaped insulating material. The side facing the battery cell film layer 5 is the non-adhesive surface 102 of the insulating tape substrate 1; the side facing the busbar 3 is the adhesive surface 101 of the insulating tape substrate 1. Furthermore, the material of the insulating tape substrate 1 can be, but is not limited to, PET (polyethylene terephthalate).

[0068] According to one embodiment of the present invention, such as Figure 2 As shown, the fixing structure 2 is located between the edge seal 7 and the battery cell film layer 5. Since the edge seal 7 is connected to the front glass 4 and the back glass 6, the present invention sets the fixing structure 2 between the edge seal 7 and the battery cell film layer 5, which can isolate the fixing structure 2 from the external environment by using the edge seal 7, reducing the impact of external moisture, impurities, etc. on the fixing structure 2.

[0069] According to one embodiment of the present invention, such as Figure 2 As shown, the fixing structure 2 is spaced at least from the outline edge of the battery cell film layer 5. This embodiment of the invention, by spacing the fixing structure 2 from the battery cell film layer 5, avoids interference with the structure of the battery cell film layer 5, thus ensuring the integrity of the battery cell film layer 5's structure.

[0070] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
