Description

Solar cell photovoltaic module and solar cell photovoltaic assembly TECHNICAL FIELD

[0001] The present application relates to the technical field of solar cells, in particular to a solar cell photovoltaic module and a solar cell photovoltaic assembly. BACKGROUND

[0002] With the rising energy prices, developing and utilizing new energy has become the main topic in the field of energy research. Since solar energy has the advantages of no pollution, no regional restrictions, and inexhaustibility, research on solar power generation has become the main direction of developing and utilizing new energy. Using solar cells to generate electricity is a main way for people to use solar energy today, but the existing solar cell pieces have the following shortcomings:

[0003] 1. The current arrangement of the cell pieces is: the piece spacing is 2mm, the string spacing is 3mm, the blank area of the entire solar cell assembly is relatively large, the power utilization rate is not high, although the laminated assembly is designed, the power is improved, but the laminated assembly increases the use of cell pieces, and the laminated cell pieces cannot generate electricity, causing the cost of the assembly to increase greatly, so the cost performance is not high;

[0004] 2. The current conventional assembly uses whole piece welding, the current of the cell piece is large, which actually causes the internal loss of the assembly to increase by several times, and the power does not increase, in order to reduce the internal loss, the thickness of the interconnection strip is increased, which reduces the anti-cracking ability of the cell piece, but at the same time causes the cost of the assembly to increase;

[0005] 3. The current cell piece mostly uses 4 main grids and 5 main grid designs, the width of the main grid is 1.1mm and 0.8mm respectively, the width of the main grid is large, which reduces the actual irradiation area of the cell piece, and further reduces the power of the cell piece; although the 12-grid cell piece assembly is designed to reduce the width of the main grid, this assembly has a small welding contact surface, high potential risk of reliability, and the welding strip used by the 12-grid cell piece is relatively thick, most of which uses 0.39mm thick copper wire material, which increases by 40% compared with the conventional welding strip of 0.27mm thickness, in order to reduce the cracking, the thickness of the packaging material has to be further increased, thereby increasing the cost of the assembly; in addition, the amount of main grid material and interconnection strip material used is large, which further increases the cost; if the welding strip is circular, there is no real surface contact, which reduces the long-term reliability of the connection between the actual main grid line and the copper-based material. The performance of the product is not improved but the risk is increased.

[0006] 4. The conventional components are designed with internal circuits formed by a series of battery pieces. If an abnormality occurs in a certain string, the hot spot protection is usually performed by a diode, and the overall power generation loss is the entire string. In the morning when the sun rises and in the afternoon when the sun is about to set, the power generation is also wasted due to shading. This waste is more significant in high-efficiency components. Therefore, under the condition of frequent shading by bird droppings, leaves and other foreign matters, the power generation is wasted due to the delay in cleaning, which is a hidden danger that seriously affects the income of the power station.

[0007] 5. With the further improvement of the efficiency of the battery piece, the efficiency of the polycrystalline PERC battery piece has risen to 19.5%, the single crystal is 20.8%, the N-type double-sided piece is 21%, and the heterojunction is 22.5% on average. The working current of the overall battery piece rises rapidly. With the application and decay, the potential compatibility between the battery pieces in the same component increases. In addition, potential external shading or internal damage during the application process, how to improve the compatibility of the battery pieces in the component, becomes a key factor in the actual long-term power generation performance. In addition, the difference in the reflection environment on the back of the double-sided battery piece component leads to a large fluctuation and difference in reflection and power generation output. These are factors that must be faced in the compatibility difference between the battery pieces in the component.

[0008] 6. In order to solve the shading or hot spot abnormalities of the battery pieces in the component, the current process uses diodes between strings to achieve current diversion and protection of abnormal battery pieces through the reverse conduction of the diode. The overall string loop is separated by starting the diode, and the voltage of the overall component is reduced according to the configuration ratio of the diode. Local abnormalities of a single battery piece result in the protection of the entire string of battery pieces by the diode, which does not provide power generation to the working loop. The damage to the power generation is based on the multiplication of the number of protected string battery pieces. In addition, as a centralized inverter loop, the voltage drop of a single string further affects other parallel string loops, resulting in an impact and damage to the final output of the busbar box. In addition, there is also a design of an intelligent optimization chip for the inter-piece string, which monitors the voltage and current of each string to achieve string optimization through the chip. This can appropriately damage the voltage of the string, but it still remains at the level of improving the string. In addition, the cost of the optimization design of the string level is relatively high, and the actual industry has not achieved market-scale acceptance.

[0009] 7. The power generation of the component is directly related to the temperature of the component during operation. The higher the operating temperature, the less the power generation of the component. With the current 5# described above, the efficiency of the battery piece is improved, and the current is rising. The working temperature of the conventional component is actually a constraint factor of the power generation. The component has hot spots or hidden cracks during operation, or the decay difference between the battery pieces between the component pieces is inconsistent, which will lead to internal loss and temperature rise of the component, and ultimately lead to the inability to optimize the power generation of the component.

[0010] 8. The current module has the latest technology of shingle module product process design, and the actual shingle module surface does not have a solder strip. In the case of battery sheet hidden cracks, the whole string is faced with the risk of blocked current output and intensified hot spot failure. In addition, the shingle itself needs to be overlapped between the battery sheets to form a circuit current output. How to compress the sheet spacing to near zero in the module design to improve the conversion efficiency of the module, the advantages and disadvantages of the shingle itself are obvious.

[0011] SUMMARY

[0012] The present application provides a kind of solar cell photovoltaic module and solar cell photovoltaic module to solve the above technical problems existing in the current solar cell photovoltaic module.

[0013] To solve the above technical problems, the present application provides a kind of solar cell photovoltaic module, including a plurality of matrix arranged battery sheet, the battery sheet light distribution has a plurality of main grid and fine grid, main grid gathers the current on the fine grid connected with it, the current gathered by main grid is transported out by interconnection strip communicated with main grid, the battery sheet is rectangular, the long side length of the battery sheet is 156-160mm, the short side length is 31-54mm, the main grid is parallel with the short side of the battery sheet, the width of the main grid is 0.4-0.7mm, preferably 0.5-0.6mm.

[0014] Need to point out that the battery sheet can be obtained by the current conventional battery sheet cutting, such as parallel cutting 2-12 pieces from the conventional battery sheet by parallel line, or directly obtaining the battery sheet of the required size by one-time ingot casting process of silicon wafer.

[0015] Optionally, the spacing between every two adjacent battery sheets is 0-0.5mm.

[0016] Optionally, the interconnection strip is divided into inter-sheet interconnection strip and inter-string interconnection strip, the inter-sheet interconnection strip transports the current on the battery sheet along the main grid direction, and the inter-string interconnection strip connects the inter-sheet interconnection strips parallel to each other in series.

[0017] Optionally, the inter-sheet interconnection strip is arranged in parallel with the main grid, the inter-string interconnection strip intersects perpendicularly with the inter-sheet interconnection strip, and connects the inter-sheet interconnection strips intersected therewith in series.

[0018] Optionally, one end of the inter-sheet interconnection strip is a light receiving surface end, and the other end is a back light surface end, the light receiving surface end is connected to the main grid of one battery sheet, and the back light surface end is connected to the back light surface main grid of another battery sheet, the inter-sheet interconnection strip is used to connect two battery sheets, and the two battery sheets are connected in series, and the inter-string interconnection strip is welded on the back light surface end.

[0019] Optionally, the width of the interconnection strip between the pieces is 0.5-0.8 mm, and the thickness is 0.12-0.18 mm; the width of the interconnection strip in series is 0.5-6 mm, and the thickness is 0.1-0.4 mm.

[0020] Optionally, the interconnection strip between the series is made of a tin-plated copper strip, a conductive adhesive tape or a transparent conductive film.

[0021] Optionally, in the solar cell photovoltaic module, the direction parallel to the long side of the cell piece is the transverse direction, and the direction parallel to the short side of the cell piece is the longitudinal direction; the number of columns of the cell piece matrix arranged in the transverse direction is 2-6; the number of rows of the cell piece matrix arranged in the longitudinal direction is 5-40; and the interconnection strip in series is arranged at a density of one row per 1-3 rows of cell pieces.

[0022] The application further provides a solar cell photovoltaic assembly comprising two or more solar cell photovoltaic modules as claimed in any one of claims 1-8 and a busbar for collecting the current of the interconnection strips.

[0023] In order to prevent the assembly from being paralyzed due to the disconnection of the assembly caused by the failure of a certain module, the prior art generally connects two adjacent solar cell photovoltaic modules by a diode or adds a virtual conductive wire and a diode, and the junction box is connected to the output by the busbar or the busbar and the virtual conductive wire. In this way, when a certain module fails, the diode and the virtual conductive wire are connected, that is, the failed module is short-circuited, thereby ensuring the normal operation of other modules.

[0024] Optionally, the solar cell photovoltaic module is arranged along the long side direction of the cell piece, and the busbar is parallel to the long side of the cell piece.

[0025] It should be noted that the direction in which the long side of the assembly is parallel to the long side of the cell piece is the horizontal direction, and the direction in which the long side of the assembly is parallel to the short side of the cell piece is the vertical direction.

[0026] Compared with the prior art, the solar cell photovoltaic assembly provided by the application has the following advantages:

[0027] 1. The application uses an oblong cell piece, the width of which is reduced relative to a conventional cell piece, that is, the number of fine grid rows on a single cell piece is reduced, the current collected on the main grid is reduced, the internal loss is reduced in square, and the power generation is improved.

[0028] 2. In the application, the width of the main grid of the cell piece is short in the main grid direction, so the current that needs to be loaded on the main grid is greatly reduced, the width of the main grid can be reduced by 40%, the shielding area of the conductive coating is greatly reduced, the light receiving area of the main body of the cell piece is increased, and the power generation efficiency is further improved; on the other hand, the amount of main grid material (silver paste) is reduced, thereby reducing the production cost.

[0029] 3. Based on the decrease of the square multiple of the internal friction, the current collection can adopt a narrower and thinner connection interconnection strip material. By adopting the interconnection strip made of ultra-thin and ultra-soft material, the arrangement between the battery pieces can adopt a very small spacing to realize a compact design. The piece spacing is within 0.5 mm, but does not affect the fragment rate of the battery piece and the yield index of the manufacturing, and does not need to block the waste between the shingle battery pieces, but because there is an interconnection strip to collect current, it can better overcome the failure caused by the hidden cracks in the application process of the battery piece. In this way, the conversion efficiency of the assembly is improved, but the cost is not increased.

[0030] 4. In the present application, the spacing between each battery piece is very small, which reduces the blank invalid area, and further improves the power generation efficiency through close arrangement;

[0031] 5. The present application realizes the wiring mode of parallel connection of battery pieces first and then series connection through the interconnection strip between the strings. In the case that a battery piece is blocked, the current can be transmitted through other battery pieces arranged in parallel to continue to deliver, thereby reducing the influence of the whole caused by the blocking of a single battery piece;

[0032] 6. By designing the size of the battery piece main grid line and the solder strip material, combining small size battery pieces, reducing the overall conventional large current to small current, reducing the internal working heat loss index, balancing the main grid line width of the battery piece, the proportion of positive silver, the width and thickness of the interconnection strip, the final light shielding width, and combining the manufacturing capacity of the string welding equipment, the maximization of the power output of the assembly is realized, and the overall vertical integrated cost of the assembly is reduced;

[0033] 7. Through the small current of small size battery pieces, the horizontal and vertical battery piece walk is realized through horizontal interconnection, and the design and process of lateral shunt can well solve the above-mentioned adaptability difference between the assembly pieces. Through horizontal interconnection and lateral shunt, the voltage is not reduced, the normal output of the battery piece is maintained, the external loss is extremely low, especially for large current high efficiency assembly and long term decay, which improves the power generation value. The early / later potential blocking of the assembly continues to improve the power generation of the assembly. Through the experimental data in the early stage, it can be seen that the new design can realize more than 5% improvement in power generation, especially for the application area with high environmental temperature. It is more obvious, which is beneficial to the rapid reduction of the degree of electricity cost of the photovoltaic industry. BRIEF DESCRIPTION OF DRAWINGS

[0042] To make the above-mentioned objects, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. It should be noted that the drawings of the present application are all simplified and use non-precise proportions, and are only used to facilitate and clarify the purpose of assisting the description of the embodiments of the present application.

[0043] Example 1 solar cell photovoltaic module

[0044] The solar cell photovoltaic module provided by the present application comprises a plurality of matrix-arranged cell sheets, as shown in Fig. 1, and the light-receiving surface of each cell sheet 10 is distributed with 4 longitudinal main grids 21 and 32 transverse fine grids 22, of course, the number of main grids 21 and fine grids 22 can be increased or decreased according to needs, and this example only gives an example, and the main grid 21 collects the current on the fine grid 22 connected thereto. The cell sheet 10 is obtained by equally dividing a common cell sheet by 2 transverse parallel lines, that is, 1 / 3 of the common cell sheet, and is a rectangle, wherein the length L1 of the long side is 156.75±0.25mm, which can be selected within the range of 156-160mm, the length L2 of the short side is 52.25±0.25mm, which can be selected within the range of 31-54mm, and the width d of the main grid 21 is 0.5-0.6mm, which can be extended to 0.4-0.7mm.

[0045] As shown in Fig. 2, the solar cell photovoltaic module comprises a plurality of matrix-arranged cell sheets 10, the direction parallel to the long side of the cell sheet 10 is the transverse direction, and the direction parallel to the short side of the cell sheet 10 is the longitudinal direction, the transverse arrangement is also the column number of the cell sheet 10 matrix, and the longitudinal arrangement is also the row number of the cell sheet matrix.

[0046] As shown in Figure 3, the partial 2x2 battery piece matrix is enlarged, and the distance G between the transverse and longitudinal adjacent edges of every two adjacent battery pieces 10 is 0-0.5mm. The current collected by the main grid 21 is transported out through the interconnection strip in communication with the main grid 21, and the interconnection strip is divided into inter-strip interconnection strips 30 and inter-string interconnection strips 33.

[0047] As shown in Figure 4, one end of the inter-strip interconnection strip 30 is the light-receiving surface end 31, and the other end is the back light surface end 32. As shown in Figures 2-4, the light-receiving surface end 31 is directly welded on the light-receiving surface main grid 21 of the right battery piece 10, and the back light surface end 33 is connected to the back light surface main grid 21 of the left battery piece 10. The inter-strip interconnection strip 30 is used to connect two battery pieces in series. The inter-string interconnection strip 33 intersects perpendicularly with the inter-strip interconnection strip 30, and the inter-string interconnection strip 33 is welded on the back light surface end 32. Of course, it can also be provided on the light-receiving surface end 31. In this embodiment, the material of the inter-string interconnection strip 33 is selected to be a tin-plated copper strip, and the inter-string interconnection strip 33 is arranged at a density of one strip per three rows, i.e., every two rows.

[0048] The width of the inter-strip interconnection strip 30 is in the range of 0.5-0.8mm, and the thickness is in the range of 0.12-0.18mm; the width of the inter-string interconnection strip is in the range of 0.5-6mm, and the thickness is in the range of 0.1-0.4mm.

[0049] It should be noted that the inter-string interconnection strip 33 can also use conductive adhesive tape or transparent conductive film, in which the transparent conductive material is interconnected on the back light surface or the light-receiving surface, which can avoid the shielding effect of the battery piece itself. This design can be used for double-sided battery, and can also be applied to battery piece assembly applications such as no main grid process and solder strip process.

[0050] It should be noted that the packaging of the battery piece 10 provided by the present application can be combined with a double-glass process and a narrow frame protection, which can solve the potential risk of battery piece 10 leakage, and can realize convenient installation, low cost and high reliability of the assembly by using the narrow frame protection. Especially for the process of double-sided battery piece, it can solve the demand of non-shielding installation of the front and back surfaces.

[0051] Embodiment 2: Horizontal solar cell photovoltaic module

[0052] As shown in Fig. 5, the horizontal solar cell photovoltaic module includes two solar cell photovoltaic modules 1 arranged side by side, i.e. along the long side of the cell sheet 10, and a bus bar 4 for collecting the current of the interconnecting bars. The bus bar 4 is parallel to the long side of the cell sheet 10. A virtual conductive wire 5 is connected between the two solar cell photovoltaic modules 1 by a diode (not shown in the figure). The virtual conductive wire 5 can be a conventional thin bus bar. The virtual conductive wire 5 is isolated from the cell sheet 10 by an insulating material. The insulating material can be a conventional EPE material or a transparent insulating EPC or a transparent back sheet, etc. to ensure that the virtual conductive wire 5 does not directly contact the cell sheet 10. A junction box (not shown in the figure) is connected to the output by the bus bar 4 and the virtual conductive wire 5. The junction box adopts a 3-pin structure. The working current of the single diode is between 15 A and 20 A.

[0053] The solar cell photovoltaic module 1 in the embodiment is different from that in Embodiment 1 in that the series interconnecting bar 33 is arranged every two rows, i.e. every other row.

[0054] The double-sided cell sheet module is suggested to adopt a transparent insulating conductive material and a transparent conductive film material. The single-sided cell sheet module can directly adopt a non-transparent insulating conductive material and a non-transparent conductive film material and be directly placed on the back.

[0055] Embodiment 3: Vertical solar cell photovoltaic module

[0056] As shown in Fig. 6, the difference from Embodiment 2 is that the cell sheet 10 matrix in the solar cell photovoltaic module 1 arranged side by side has 3 columns and 20 rows. A longitudinal solar cell photovoltaic module is arranged. The series interconnecting bar 33 is arranged every three rows, i.e. every other two rows.

[0057] Obviously, those skilled in the art can make various modifications and variations to the application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the application fall within the scope of the claims of the application and their equivalent technologies, the application is also intended to include these modifications and variations.
