Description

Technical Field

[0001] This application relates to the field of solar cells, and in particular to a frameless solar cell module with an H-shaped structure. Background Technology

[0002] Because single-cell solar cells have low output voltage, and unencapsulated cells are prone to electrode detachment due to environmental factors, a certain number of single cells must be sealed in series and parallel to form a solar cell module. This prevents corrosion of the cell electrodes and interconnects. Encapsulation also prevents cell breakage and facilitates outdoor installation. The quality of the encapsulation determines the lifespan and reliability of the solar cell module. A solar cell module consists of high-efficiency crystalline silicon solar cells, ultra-white textured tempered glass, EVA, a transparent TPT backsheet, and an aluminum alloy frame. It features a long lifespan and strong mechanical resistance to external pressure. Figure 1 As shown, the conventional structural forms of solar cell modules include the following: glass-cased modules, bottom-box modules, flat-panel modules, and fully sealed modules without cover plates.

[0003] Among them, flat-plate modules are currently the most widely used solar cell modules. They have good sealing properties, which can protect the solar cells to the greatest extent and prevent corrosion of the cell electrodes and interconnects. They also prevent the cells from breaking and are convenient for outdoor installation. However, they use more materials and are more expensive. In addition, there is no isolation layer between solar cell groups. If a solar cell is damaged, causing a decrease in the efficiency of a solar cell group or rendering it ineffective, it is difficult to safely remove the solar cell group. In this case, the entire solar cell module needs to be replaced, resulting in high maintenance costs.

[0004] While the cost of the coverless all-glue sealing component is low and it is suitable for widespread use, the coverless structure makes its overall environmental resistance lower than that of flat panel components, glass shell components and bottom box components. Similarly, its structural strength is also lower and it is more prone to damage, making it difficult to promote the use of coverless all-glue sealing components.

[0005] Glass-cased and box-type modules have similar performance to flat-panel modules, but their overall cost is not advantageous. Their performance and installation methods are similar to those of flat-panel modules.

[0006] If, without affecting the practical performance of solar cell modules, a combination of coverless fully sealed modules and flat-plate modules can be achieved, reducing the cost of flat-plate modules and improving the environmental resistance and structural strength of coverless fully sealed modules, then more cost-effective solar cell modules can be developed. Summary of the Invention

[0007] The purpose of this application is to improve existing solar cell modules and create high-performance and lower-cost solar cell modules. Compared with the prior art, it provides a frameless solar cell module with an H-shaped structure. The reinforcing separator is embedded on the upper surface of the adhesive. The reinforcing separator is located between two solar cell groups. The reinforcing separator is located at the upper end of the substrate. The upper end of the reinforcing separator is attached to the bottom surface of the glass cover plate. The two ends of the reinforcing separator are located on both sides of the adhesive and are on the same plane as the corresponding adhesive sidewalls. The cross-section of the reinforcing separator is H-shaped.

[0008] This technology improves existing solar cell modules. Solar cell modules with glass covers offer better environmental resistance and a longer lifespan compared to existing coverless, fully sealed modules. The reinforced separators enhance the structural strength of the solar cell modules. Furthermore, compared to existing flat-plate, glass-cased, and box-type modules, the cost is lower, leading to cost savings. The reinforced separators also provide effective separation; if a solar cell fails, causing a reduction in efficiency or malfunction of an entire solar cell module, workers can simply cut along the corresponding reinforced separator to disassemble the module. A new solar cell module can then be installed in the appropriate position using adhesive, thus completing the maintenance of the solar cell modules and reducing maintenance costs.

[0009] Furthermore, the reinforcing separator has multiple filling holes, which are equidistantly distributed along the length of the reinforcing separator. The sidewall of the reinforcing separator closest to the solar cell intersects with the upper surface of the reinforcing separator at a chamfer. By opening the filling holes on the reinforcing separator, the adhesive can be quickly filled into the gap between the web and the flange of the reinforcing separator during the adhesive filling process, thus avoiding unfilled areas within the reinforcing separator that could affect the overall structural strength of the solar cell array.

[0010] Furthermore, the partition column is reinforced with positioning blocks fixed to the side wall near the solar cell. Multiple positioning blocks are provided, and every two positioning blocks form a positioning element. The side wall of the solar cell abuts against the side wall of the positioning element formed by two positioning blocks. Multiple sets of positioning elements are provided, and each set of positioning elements corresponds to multiple solar cells. The positioning blocks can limit the position of the solar cells. During the manufacturing process of solar cell modules, this helps to fix the solar cells and prevent them from shifting during the sealing process. At the same time, it facilitates the positioning and installation of the solar cells by the staff.

[0011] Furthermore, a partition plate is snapped between the two positioning blocks that make up the positioning component. The partition plate is set vertically, with its upper end face abutting against the bottom surface of the glass cover plate. There is a gap between the partition plate and the side wall of the reinforcing partition column, and the gap is filled with adhesive. The partition plate further limits the position of the solar cell, making it easier for workers to determine the installation position of the solar cell. At the same time, the gap formed with the reinforcing partition column allows for cutting when the solar cell array needs to be disassembled, which helps to protect the solar cell in the solar cell array during disassembly.

[0012] Furthermore, the height of the upper surface of the positioning block is lower than the height of the upper surface of the solar cell, the separator is tilted, the upper end of the separator is offset away from the solar cell, and the lower sidewall of the separator is in contact with the sidewall of the solar cell. This arrangement can effectively prevent the positioning block and the separator from blocking the upper surface of the solar cell, thereby avoiding adverse effects on the working efficiency of the solar cell.

[0013] Optionally, the upper surfaces of the reinforcing divider and the divider sheet are coated with a colorant that is distinctly different from the adhesive and eye-catching. The different colors allow staff to more intuitively observe the gap between the reinforcing divider and the divider sheet, thus helping to remind staff of the cutting position.

[0014] Furthermore, an anti-seepage strip is integrally formed on the upper surface of the bottom plate. There are two anti-seepage strips, which are located at both ends of the upper surface of the bottom plate. When rainwater corrodes the connection between the adhesive and the bottom plate, causing gaps, the anti-seepage strips prevent rainwater from penetrating into the gaps between the adhesive and the bottom plate, thereby avoiding significant corrosion damage to the connection between the adhesive and the bottom plate.

[0015] Furthermore, the bottom surface of the substrate is bonded to the bottom plate with an adhesive, and a support strip is fixed on the upper surface of the substrate. The upper end of the support strip contacts the lower end of the solar cell. The support strip supports the solar cell and, together with the positioning block and the separator, limits the position of the solar cell, thereby facilitating the installation of the solar cell by the workers before the adhesive is injected for sealing.

[0016] Furthermore, the adhesive contains a battery cavity and a bottom cavity, which are used to accommodate the solar cell and the substrate, respectively. Separators and connectors are integrally formed on the adhesive. The separators fill the grooves of the reinforcing separators, and the connectors fill the filling holes. The connectors connect the separators and the adhesive. The separators and connectors formed after the adhesive is injected can effectively fix the reinforcing separators and fill the gaps on the reinforcing separators, thereby facilitating the reinforcing separators to play a role in strengthening the overall structural strength and preventing the reinforcing separators from separating from the adhesive.

[0017] Furthermore, interconnecting wires are distributed among the multiple solar cells that make up the solar cell array. The two ends of the interconnecting wires are fixed to the positive and negative electrodes of two adjacent solar cells, respectively. Electrode leads are fixed at both ends of the solar cell array.

[0018] Compared to existing technologies, the advantages of this application are:

[0019] This invention improves upon existing solar cell modules. Solar cell modules with glass covers have better environmental resistance and longer service life compared to existing coverless, fully sealed modules. Furthermore, the reinforced separators enhance the structural strength of the solar cell module. At the same time, compared to existing flat-plate modules, glass-shell modules, and box-type modules, the cost is lower, which is more conducive to cost savings. In addition, the reinforced separators provide good separation and reduce the maintenance cost of the solar cell module.

[0020] During the adhesive filling process, the adhesive can be quickly filled through the filling holes into the gap between the web and the flange of the reinforcing separator, avoiding the formation of unfilled areas within the reinforcing separator that would affect the overall structural strength of the solar cell array.

[0021] Positioning blocks can limit the position of solar cells, which helps to fix the solar cells during the manufacturing process of solar cell modules, prevents the solar cells from shifting during the sealing process, and facilitates the positioning and installation of solar cells by workers.

[0022] The separator further limits the position of the solar cells, making it easier for workers to determine the installation location of the solar cells. At the same time, the gap formed between the separator and the reinforcing separator allows for cutting when the solar cell array needs to be disassembled, which helps to protect the solar cells in the solar cell array during disassembly.

[0023] This effectively prevents the positioning blocks and separators from obstructing the upper surface of the solar cells, thus avoiding any adverse impact on the working efficiency of the solar cells.

[0024] The upper surfaces of both the reinforced divider and the divider plate are coated with a bright and distinctive color that is clearly different from the adhesive. The different colors allow staff to more intuitively observe the gap between the reinforced divider and the divider plate, thus helping to remind staff of the cutting position.

[0025] When rainwater corrodes the connection between the adhesive and the base plate, creating gaps, the waterproof strip prevents rainwater from penetrating into these gaps, thus avoiding significant corrosion damage to the connection between the adhesive and the base plate.

[0026] The support strips support the solar cells and, together with the positioning blocks and separators, limit the position of the solar cells, thus facilitating the installation of the solar cells by the workers before the adhesive is injected for sealing.

[0027] The separation and connection bodies formed after the adhesive is injected can effectively fix the reinforcing partition column and fill the gaps on the reinforcing partition column, thereby facilitating the reinforcing partition column to play a role in strengthening the overall structural strength and preventing the reinforcing partition column from separating from the adhesive.

Detailed Implementation

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] Example 1:

[0042] This invention provides a frameless solar cell module with an H-shaped structure. Please refer to [link / reference]. Figure 2-4 The assembly includes a solar cell 1, a glass cover plate 2, a bottom plate 3, an adhesive 4, and a substrate 6. The solar cell 1 is bonded to the glass cover plate 2, the bottom plate 3, and the substrate 6 by the adhesive 4. Multiple solar cells 1 are connected in series to form a solar cell array. The solar cell 1 uses existing crystalline silicon solar cells. The specific manufacturing material can be selected as either monocrystalline silicon solar cells or polycrystalline silicon solar cells as needed. The former has a higher manufacturing cost but a higher photoelectric conversion efficiency (around 17%, with the highest reaching 24%). The latter has a lower manufacturing cost but a relatively lower photoelectric conversion efficiency (around 15%).

[0043] The glass cover 2 uses low-iron patterned tempered glass commonly used in existing technologies, with a typical thickness of 3.2mm ± 0.3mm. Within the wavelength range of the solar cell's spectral response (350~1100nm), the direct transmittance of sunlight with a standard thickness of 3mm should be greater than 91%. It should also have a high reflectivity for infrared light greater than 1200nm. The iron content (Fe2O3) of the solar cell glass should not exceed 0.015%.

[0044] The bottom plate 3 is mainly made of TPT, TPE or PET, and the specific material can be selected according to the actual use requirements;

[0045] Adhesive 4 is made of EVA material, a copolymer of ethylene and vinyl acetate. EVA is a thermosetting hot melt adhesive; it is non-sticky at room temperature for ease of handling, but under certain hot pressing conditions, it melts, bonds, cross-links, and cures, becoming completely transparent. Long-term practical experience has proven that, compared with other materials, EVA has achieved quite satisfactory results in solar cell encapsulation and outdoor applications. The thickness of EVA is... Between them, the surface must be flat and the thickness uniform. It contains a cross-linking agent that can cross-link at a curing temperature of 150℃ and form a stable adhesive layer using an extrusion molding process.

[0046] Substrate 6 mainly uses TPF or TPT high-molecular fluorine film, which needs to have good weather resistance, be able to block moisture from entering from the back, not change at the lamination temperature, and be firmly bonded to the adhesive material.

[0047] The adhesive 4 has a reinforcing partition post 5 embedded on its upper surface. The reinforcing partition post 5 is made of aluminum alloy of 6063T5 or higher, and its surface must be anodized with an oxide layer thickness greater than 20μm. This is used to enhance the overall mechanical strength of the solar cell module. The reinforcing partition post 5 is located between two solar cell groups and on the upper end of the substrate 6. The upper end of the reinforcing partition post 5 is attached to the bottom surface of the glass cover plate 2. The two ends of the reinforcing partition post 5 are located on both sides of the adhesive 4 and are on the same plane as the corresponding sidewalls of the adhesive 4. The cross-section of the reinforcing partition post 5 is H-shaped and consists of a web and a flange. Its cross-sectional area distribution is more optimized and the strength-to-weight ratio is more reasonable. It has strong bending resistance in all directions, saves costs, and has a light structural weight. This strengthens the overall structural strength of the solar cell module while reducing the production cost of the solar cell module. It also separates the solar cell groups formed by the solar cells 1. When one group of solar cell groups needs to be disassembled, it can protect the remaining solar cell groups and prevent them from being damaged, effectively reducing the maintenance cost of the solar cell module.

[0048] Please see Figure 9 The reinforcing partition column 5 has multiple filling holes 501, which are equidistantly distributed along the length of the reinforcing partition column 5. The side wall of the reinforcing partition column 5 near the solar cell 1 intersects with the upper surface of the reinforcing partition column 5 at a chamfer. The chamfer facilitates the cutting work when the workers disassemble the solar cell 1 to form the solar cell assembly. When assembling the solar cell module, the adhesive 4 quickly fills the gap between the web and the flange of the reinforcing partition column 5 through the filling holes 501, avoiding the formation of unfilled areas in the reinforcing partition column 5, which would affect the overall structural strength of the solar cell assembly.

[0049] Please see Figure 7The reinforcing partition column 5 is fixed with a positioning block 502 near the side wall of the solar cell 1. The positioning block 502 is perpendicular to the flange of the reinforcing partition column 5. There are multiple positioning blocks 502, and every two positioning blocks 502 form a positioning element. The side wall of the solar cell 1 abuts against the side wall of the positioning element formed by two positioning blocks 502. There are multiple sets of positioning elements, and each set of positioning elements corresponds to a multiple solar cell 1. During the assembly process, the worker only needs to snap the solar cell 1 between the two positioning blocks 502 that make up the positioning element to prevent the solar cell 1 from shifting in an orderly and equidistant manner. At the same time, during the injection of adhesive 4, the solar cell 1 is not easy to shift, which is more conducive to the production of solar cell modules.

[0050] Please see Figure 5 and Figure 7 A partition plate 503 is engaged between the two positioning blocks 502 that make up the positioning component. The partition plate 503 is perpendicular to the positioning blocks 502 and parallel to the flange of the reinforcing partition column 5. The partition plate 503 is vertically arranged, and its upper end face abuts against the bottom surface of the glass cover plate 2. There is a gap between the partition plate 503 and the side wall of the reinforcing partition column 5. The gap is filled with adhesive 4. The partition plate 503 further limits the positioning of the solar cell 1. When placing the solar cell 1, the operator only needs to place one side of the solar cell 1 against the partition plate 503, and the adjacent two sides are engaged between the two positioning blocks 502. This ensures that the installation positions of multiple solar cells 1 are consistent. At the same time, the gap formed with the reinforcing partition column 5 allows for cutting when the solar cell array needs to be disassembled. During the cutting process, the cutting tool is separated from the solar cell 1, which is beneficial for protecting the solar cell 1 in the solar cell array during disassembly.

[0051] Please see Figure 5 and Figure 7 The upper surface of the positioning block 502 is lower than the upper surface of the solar cell 1. The separator 503 is inclined and its upper end is offset away from the solar cell 1. The lower sidewall of the separator 503 is in contact with the sidewall of the solar cell 1. This can effectively prevent the positioning block 502 and the separator 503 from blocking the upper surface of the solar cell 1, thereby avoiding adverse effects on the working efficiency of the solar cell 1.

[0052] Please see Figure 7 and Figure 10The upper surfaces of the reinforcing separator 5 and the separator 503 are coated with a colorant that is distinctly different from and eye-catching than the adhesive 4. The different colors allow workers to more intuitively observe the gap between the reinforcing separator 5 and the separator 503, thereby helping to remind workers of the cutting position.

[0053] Please see Figure 3 The lower base plate 3 has an integrally formed anti-seepage strip 301 on its upper surface. There are two anti-seepage strips 301, which are located at both ends of the upper surface of the lower base plate 3. The anti-seepage strips 301 are made of the same material as the lower base plate 3. When rainwater corrodes the connection between the adhesive 4 and the lower base plate 3, causing gaps, the anti-seepage strips 301 prevent rainwater from penetrating into the gaps between the adhesive 4 and the lower base plate 3, thereby avoiding significant corrosion damage to the connection between the adhesive 4 and the lower base plate 3.

[0054] Please see Figure 8 The bottom surface of the substrate 6 is bonded to the bottom plate 3 by adhesive 4. A support strip 601 is fixed on the upper surface of the substrate 6. The upper end of the support strip 601 contacts the lower end of the solar cell 1. The support strip 601 is provided with through holes, which allow adhesive 4 to fill the gap between the substrate 6 and the solar cell 1, thereby providing support while avoiding the formation of gaps during the filling process.

[0055] Please see Figure 6 The adhesive 4 has a battery cavity 401 and a bottom cavity 404, which are used to accommodate the solar cell 1 and the substrate 6, respectively. A separator 402 and a connector 403 are integrally formed on the adhesive 4. The separator 402 fills the groove of the reinforcing separator 5, and the connector 403 fills the filling hole 501. The connector 403 connects the separator 402 and the adhesive 4. The separator 402 and the connector 403 formed after the adhesive 4 is injected can effectively fix the reinforcing separator 5 and fill the gaps on the reinforcing separator 5, thereby facilitating the reinforcing separator 5 to play a role in strengthening the overall structural strength and preventing the reinforcing separator 5 from separating from the adhesive 4.

[0056] Please see Figure 1 and Figure 5Interconnecting wires 102 are distributed among the multiple solar cells 1 that make up the solar cell array. The two ends of the interconnecting wires 102 are fixed to the positive and negative electrodes of two adjacent solar cells 1, respectively. Electrode leads 101 are fixed at both ends of the solar cell array. The interconnecting wires 102 are used to connect multiple solar cells 1 in the same column to form a solar cell array. The electrode leads 101 at the ends of multiple solar cell arrays are connected in parallel to form a solar cell module, thereby forming a complete frameless solar cell module with an H-shaped structure.

[0057] Example 2:

[0058] This invention provides a frameless solar cell module with an H-shaped structure. Please refer to [link / reference]. Figure 9 The main difference from the above solution is that the reinforcing partition column 5 provided in this embodiment does not have positioning blocks 502 and partition plates 503 on both sides, which simplifies the structural composition of the solar cell module. During the sealing process, the staff needs to use tools to position and place the solar cell 1, which further reduces the weight of the solar cell module and lowers the production cost.

[0059] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
