Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and particularly relates to a perovskite battery module. Background Art

[0002] Perovskite photovoltaic modules have become a hot topic pursued by the current photovoltaic industry due to their high conversion efficiency and adjustable bandgap. At the same time, they have the advantages of low manufacturing cost and simple manufacturing process. They are the optimal solution to improve efficiency and reduce costs in the current photovoltaic field, with great potential and a broad market.

[0003] In the related art, a perovskite battery is a sub-battery string formed by connecting several sub-battery units in series, which includes a positive electrode and a negative electrode located at both ends of the first and last positions. Currently, for the convenience of processing, usually an extraction hole is opened on the glass backplane, and at the same time, the positive and negative electrodes of the perovskite battery are led out, and a junction box is installed.

[0004] However, it has certain deficiencies: because the positive and negative electrode structures located at both ends need to be led out through the extraction hole by setting a bus bar, and the distance between the positive and negative electrode structures and the extraction hole is generally large, and the bus bar needs to be attached to the cell film surface of the perovskite battery or attached to the front glass plate. If it is attached to the front glass plate, a large edge clearing distance is required, resulting in a loss of a part of the power generation area of the cell film surface; if it is attached to the cell film surface, since the bus bar is long and has a large contact area with the cell film surface, when performing high-temperature lamination on the perovskite photovoltaic module, the insulating tape is likely to lift the film surface of the perovskite battery, resulting in delamination of the cell film surface in the perovskite battery. Content of the Utility Model

[0005] In view of this, the utility model provides a perovskite battery module to solve the technical problem of delamination of the perovskite photovoltaic module.

[0006] The utility model provides a perovskite battery module, including:

[0007] A front glass plate;

[0008] A perovskite battery, arranged on the front glass plate; the perovskite battery includes a positive electrode structure and a negative electrode structure on the same side of the front glass plate, and the positive electrode structure and the negative electrode structure are located at both ends of the sub-battery string in the perovskite battery;

[0009] A glass backplane, covering the perovskite battery; extraction holes are respectively opened on the glass backplane corresponding to the positive electrode structure and the negative electrode structure, and a junction box is arranged corresponding to each extraction hole.

[0010] Beneficial effects: By setting the glass front plate as the support and substrate of the perovskite battery, a stable attachment platform is provided for the perovskite battery. Lead-out holes are respectively arranged on the glass back plate corresponding to the positive electrode structure and the negative electrode structure; through the lead-out holes, the currents of the positive electrode structure and the negative electrode structure can be smoothly transmitted from the inside of the perovskite battery to the outside. Junction boxes are arranged at positions corresponding to each lead-out hole, which can conveniently connect external circuits and improve the power output efficiency; moreover, by adopting the form of a split junction box and arranging the junction boxes on both sides of the perovskite battery module, the connection wires inside the perovskite battery module can be prevented from being attached to the film surface of the perovskite battery module, thereby effectively avoiding the peeling of the perovskite film layer; and the positive and negative electrode structures are respectively led out from the corresponding lead-out holes, and the lead-out distance is greatly shortened, which can greatly reduce the use length of the bus bar, reduce the internal resistance of the perovskite battery and reduce the cost. Furthermore, since there is no need to separately attach the bus bar in the edge cleaning area, the width of the edge cleaning area can be reduced, thereby increasing the area of the battery core film layer and further improving the overall power generation efficiency. The utility model can improve the power generation efficiency of the battery while avoiding the peeling of the battery core film layer of the perovskite battery.

[0011] In an alternative embodiment, in the direction of the orthographic projection of the glass back plate, the lead-out holes respectively correspond exactly to the positive electrode structure and the negative electrode structure.

[0012] Beneficial effects: In the direction of the orthographic projection of the glass back plate, by respectively corresponding the lead-out holes exactly to the positive electrode structure and the negative electrode structure, the connection wires led out from the positive and negative electrodes of the perovskite battery can be directly connected to the external circuit through the lead-out holes, reducing the complexity of the connection of the positive and negative electrode structures of the perovskite battery and the length of the circuit, and there is no need to attach the bus bar in the edge cleaning area or on the battery core film surface.

[0013] In an alternative embodiment, in the direction of the orthographic projection of the glass back plate, the lead-out holes are respectively offset from the positive electrode structure and the negative electrode structure, and the orthographic projection of the lead-out holes is located within the area of the perovskite battery.

[0014] Beneficial effects: In the direction of the orthographic projection of the glass back plate, by setting the lead-out holes at positions offset from the centers of the positive and negative electrode structures and making the orthographic projection of the lead-out holes within the area of the perovskite battery, in this embodiment, the distance between the lead-out holes and the edge of the glass back plate can be adjusted according to requirements, the electrical safety distance can be designed according to the voltage of the battery module, and the distance can also be designed according to the mounting bracket or the carrier to be mounted.

[0015] In an alternative embodiment, both the positive electrode structure and the negative electrode structure include an electrode layer, a conductive strip and a bus bar;

[0016] The conductive strip is arranged on the electrode layer and is electrically connected to the electrode layer;

[0017] The bus bar includes an adhering section and a drainage section. The adhering section is electrically connected to the conductive strip, and the drainage section extends out from the lead-out hole.

[0018] Beneficial effects: In a perovskite solar cell, the current generated by the electrode layers in the positive electrode structure and the negative electrode structure first flows from the electrode layers to the conductive strip, and then the current is transmitted through the conductive strip to the adhering section of the bus bar; after the adhering section collects the current, it transmits the current to the drainage section; the drainage section passes through the lead-out hole and leads the current out of the battery to be connected to an external circuit, realizing the output and utilization of electrical energy.

[0019] In an alternative embodiment, the adhering section is clamped between the electrode layer and the conductive strip and is electrically connected to the conductive strip.

[0020] Beneficial effects: Clamping the adhering section between the electrode layer and the conductive strip can ensure stable adhesion of the bus bar and also prevent problems such as poor contact caused by loosening of the bus bar.

[0021] In an alternative embodiment, both the positive electrode structure and the negative electrode structure further include insulating sheets. The insulating sheets correspond to the lead-out holes and are clamped between the electrode layer and the bus bar; the adhering section is clamped between the insulating sheet and the conductive strip, and the drainage section extends out from a side intersecting the length direction of the conductive strip.

[0022] Beneficial effects: The insulating sheets corresponding to the lead-out holes and clamped between the electrode layer and the bus bar can isolate the bus bar from the electrode layer, preventing direct contact between the electrode layer and the bus bar. By electrically connecting the bus bar to the conductive strip instead of the electrode layer, a more stable current output can be achieved. Extending the drainage section from a side intersecting the length direction of the conductive strip can adapt to the overall structure and layout of the perovskite solar cell module, and the lead-out method intersecting the length direction of the conductive strip can reduce interference with the conductive strip and also make the lead-out of the current smoother and more stable.

[0023] In an alternative embodiment, the lead-out position of the drainage section is close to the edge of the glass backplane.

[0024] Beneficial effects: By positioning the lead-out position of the drainage section close to the edge of the glass backplane, the edge space of the glass backplane can be fully utilized; interference with the internal components of the perovskite solar cell module can be avoided, which helps to improve the space utilization rate of the perovskite solar cell module. Moreover, the lead-out position close to the edge of the glass backplane makes it easier to connect the drainage section to an external circuit, facilitating the introduction or lead-out of the external circuit and reducing the length and complexity of the connection lines.

[0025] In an alternative embodiment, the lead-out position of the drainage section is on the side far from the edge of the glass backplane.

[0026] Advantageous effects: By setting the lead-out position of the drainage section on the side far from the edge of the glass backplane, the interference of the external environment on the drainage section can be reduced, and the stability of the perovskite battery module can be improved; at the same time, the drainage section faces away from the edge of the glass backplane, which can increase the distance from the drainage section to the edge of the glass backplane, thereby ensuring the electrical safety distance and enabling the opening position of the lead-out hole to be closer to the edge of the glass backplane.

[0027] In an alternative embodiment, in the length direction of the conductive strip, the lead-out hole is opened at any position on the glass backplane.

[0028] Advantageous effects: By opening the lead-out hole at any position on the glass backplane, the position of the lead-out hole can be flexibly selected on the glass backplane according to specific requirements and actual situations, providing greater design freedom for the layout and connection of the perovskite battery module, and meeting the requirements of different application scenarios.

[0029] In an alternative embodiment, it further includes a sealant, the sealant is arranged between the glass front plate and the glass backplane, and the sealant is arranged in the edge area of the glass front plate and the glass backplane. The glass front plate, the glass backplane and the sealant together form a sealing cavity for sealing the perovskite battery.

[0030] Advantageous effects: By arranging the sealant between the glass front plate and the glass backplane and in the edge area of the glass front plate and the glass backplane, the gap between the glass front plate and the glass backplane can be filled to ensure that impurities such as moisture and oxygen in the external environment do not enter the interior of the perovskite battery module. By jointly forming a sealing cavity for sealing the perovskite battery by the glass front plate, the glass backplane and the sealant, it can effectively prevent impurities such as moisture and dust in the external environment from entering the interior of the perovskite battery module, thereby protecting the perovskite battery and the like from damage, effectively improving the reliability and stability of the perovskite battery module, and extending its service life.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0044] In the related art, the encapsulation method of perovskite photovoltaic modules is to lead the bus bar out from a single hole in the middle of the perovskite photovoltaic module and connect it to the junction box; in order to fix the bus bar, an insulating tape needs to be pasted under the bus bar; however, the insulating tape will lift the film surface of the perovskite battery during the high-temperature lamination of the perovskite photovoltaic module, resulting in delamination of the perovskite photovoltaic module. Moreover, the use of the middle bus bar connection method will result in the use of more bus bars and insulating tapes, a large consumption of bus bars, an increase in cost, and a large internal resistance loss due to the long bus bar.

[0045] In view of this, the present utility model provides a perovskite battery module. By adopting the form of a split junction box and arranging the junction box on both sides of the perovskite battery module, it is possible to avoid the connection lines inside the perovskite battery module from converging on the film surface of the perovskite battery module, thereby effectively avoiding delamination of the perovskite film layer.

[0046] The following combines Figures 1 to 9 to describe the embodiments of the present utility model.

[0047] According to an embodiment of the present utility model, on the one hand, with reference to Figures 1 to 5 , a perovskite battery module is provided, including: a glass front plate 100; a perovskite battery 200 disposed on the glass front plate 100; the perovskite battery 200 includes a positive electrode structure and a negative electrode structure on the same side of the glass front plate 100, and the positive electrode structure and the negative electrode structure are located at the head and tail ends of the sub-battery strings in the perovskite battery 200; a glass back plate 300 covering the perovskite battery 200; lead-out holes 310 are respectively formed on the glass back plate 300 corresponding to the positive electrode structure and the negative electrode structure, and a junction box is disposed corresponding to each lead-out hole 310.

[0048] In this embodiment, by setting the glass front plate 100 as the support and substrate of the perovskite battery 200, a stable attachment platform is provided for the perovskite battery 200. The perovskite battery 200 is attached to the glass front plate 100, and the orthographic projection of the perovskite battery 200 on the glass front plate 100 is within the range of the glass front plate 100. The positive electrode structure and the negative electrode structure of the perovskite battery 200 are respectively arranged on the same side surface of the glass front plate 100, and the positive electrode structure and the negative electrode structure are located at the head and tail ends of the sub-battery string in the perovskite battery 200, making it more convenient for the perovskite battery 200 to connect to an external circuit; further, lead-out holes 310 are respectively arranged on the glass back plate 300 corresponding to the positive electrode structure and the negative electrode structure; by setting the lead-out holes 310, the currents of the positive electrode structure and the negative electrode structure can be respectively and smoothly transmitted from the inside of the perovskite battery 200 to the outside. A junction box is arranged at each position corresponding to the lead-out holes 310, which can conveniently connect to an external circuit and improve the output efficiency of electric energy; moreover, by adopting the form of a split junction box and arranging the junction box on both sides of the perovskite battery module, the connection wires inside the perovskite battery module can be prevented from being attached to the film surface of the perovskite battery module, thereby effectively avoiding the peeling of the perovskite film layer; and the positive and negative electrode structures are respectively led out from the corresponding lead-out holes 310, and the lead-out distance is greatly shortened, which can greatly reduce the use length of the bus bar 230, reduce the internal resistance of the perovskite battery 200 and reduce the cost. Furthermore, since there is no need to separately attach the bus bar 230 in the edge cleaning area, the width of the edge cleaning area on the glass front plate 100 can be reduced, thereby increasing the area of the cell film layer and further improving the overall power generation efficiency. The utility model can improve the power generation efficiency of the battery while avoiding the peeling of the cell film layer of the perovskite battery 200.

[0049] As Figure 3 shown, in one of the embodiments, in the orthographic projection direction of the glass back plate 300, the lead-out holes 310 respectively correspond exactly to the positive electrode structure and the negative electrode structure.

[0050] In this embodiment, in the orthographic projection direction of the glass back plate 300, by respectively corresponding the lead-out holes 310 exactly to the positive electrode structure and the negative electrode structure, the connection wires led out from the positive and negative electrodes of the perovskite battery 200 can be directly connected to the external circuit through the lead-out holes 310, reducing the complexity of the connection of the positive and negative electrode structures of the perovskite battery 200 and the length of the circuit, and there is no need to attach the bus bar 230 in the edge cleaning area or on the cell film surface.

[0051] As Figure 4 shown, in one of the embodiments, in the orthographic projection direction of the glass back plate 300, the lead-out holes 310 are respectively offset from the positive electrode structure and the negative electrode structure, and the orthographic projection of the lead-out holes 310 is within the area of the perovskite battery 200.

[0052] In this embodiment, in the orthographic projection direction of the glass backplane 300, by setting the lead-out hole 310 at a position offset from the center of the bias positive and negative electrode structure, and the orthographic projection of the lead-out hole 310 is within the perovskite cell 200 region. In this embodiment, the distance between the lead-out hole 310 and the edge of the glass backplane 300 can be adjusted according to requirements. The electrical safety distance can be designed according to the voltage of the battery module, and the distance can also be designed according to the mounting bracket or the carrier to be mounted.

[0053] As Figures 5 to 9 shown, in one of the embodiments, both the positive electrode structure and the negative electrode structure include an electrode layer 210, a conductive strip 240, and a bus bar 230; the conductive strip 240 is disposed on the electrode layer 210 and is electrically connected to the electrode layer 210; the bus bar 230 includes an attachment section 231 and a drainage section 232, the attachment section 231 is electrically connected to the conductive strip 240, and the drainage section 232 is led out from the lead-out hole 310.

[0054] In this embodiment, the positive electrode structure and the negative electrode structure have the same structure, both including an electrode layer 210, a conductive strip 240, and a bus bar 230. Since a clear edge area is provided on the glass front plate 100, it is necessary to ensure that the size of the electrode layer 210 is smaller than the clear edge area on the glass front plate 100 to ensure the sealing performance after the perovskite battery module is sealed. The conductive strip 240 is stacked on the electrode layer 210, and the size of the conductive strip 240 is smaller than that of the electrode layer 210. Then, the conductive strip 240 is electrically connected to the electrode layer 210 to provide a good conductive path and ensure that current can flow smoothly from the electrode layer 210 to the conductive strip 240. In the perovskite cell 200, the current generated by the electrode layer 210 in the positive electrode structure and the negative electrode structure is transmitted through the conductive strip 240 to the attachment section 231 of the bus bar 230; after the attachment section 231 collects the current from the conductive strip 240, the current is transmitted to the drainage section 232; the drainage section 232 passes through the lead-out hole 310 and leads the current out of the battery to be connected to an external circuit, realizing the output and utilization of electrical energy. Since the attachment section 231 is closely connected to the conductive strip 240, the attachment section 231 needs to have good conductivity and mechanical stability. Specifically, it can be made of materials such as metal sheets or conductive adhesives to ensure that current can flow smoothly through. The material of the drainage section 232 is the same as that of the attachment section 231 to ensure the same conductivity of the entire bus bar 230. To adapt to different positions of the lead-out hole 310 and different external circuit connection methods, the shape and length of the drainage section 232 can be designed according to actual installation requirements.

[0055] The bus bar 230 provides a fast conductive path, ensuring uniform current distribution and concentrated transmission, effectively improving the current transmission efficiency and stability. Moreover, by leading the bus bar 230 out from both sides of the perovskite battery 200, the length of the bus bar 230 can be effectively reduced, thereby reducing the internal resistance of the perovskite battery 200 components and also reducing the manufacturing cost.

[0056] In one embodiment, the pasting section 231 is clamped between the electrode layer 210 and the conductive strip 240 and is electrically connected to the conductive strip 240. By clamping the pasting section 231 between the electrode layer 210 and the conductive strip 240, the stable pasting of the bus bar 230 can be ensured, and problems such as poor contact caused by the loosening of the bus bar 230 can also be prevented.

[0057] In one embodiment, both the positive electrode structure and the negative electrode structure further include an insulating sheet 220. The insulating sheet 220 corresponds to the lead-out hole 310 and is clamped between the electrode layer 210 and the bus bar 230; the pasting section 231 is clamped between the insulating sheet 220 and the conductive strip 240, and the diversion section 232 is led out from one side intersecting the length direction of the conductive strip 240.

[0058] In this embodiment, the insulating sheet 220 corresponds to the lead-out hole 310 and is clamped between the electrode layer 210 and the bus bar 230, which can isolate the bus bar 230 from the electrode layer 210 and prevent direct contact between the electrode layer 210 and the bus bar 230. By electrically connecting the bus bar 230 to the conductive strip 240 instead of the electrode layer 210, a more stable current can be output. The diversion section 232 is led out from one side intersecting the length direction of the conductive strip 240 to adapt to the overall structure and layout of the perovskite battery 200 components, and the lead-out method intersecting the length direction of the conductive strip 240 can reduce the interference to the conductive strip 240 and also make the current lead-out smoother and more stable.

[0059] In other achievable ways, such as Figure 5 shown, butyl rubber is filled in the lead-out hole 310, and further, butyl rubber with a preset width is laid around the lead-out hole 310 for external hole plugging. Specifically, butyl rubber with a length and width of 10 mm can be laid; by the method of external hole plugging, it can prevent the butyl rubber from overflowing onto the film surface of the perovskite battery 200 during lamination and prevent the perovskite battery components from discoloring. The specific laying width can be determined according to requirements and is not limited to 10 mm.

[0060] Such as Figure 6 、 Figure 7 shown, in one embodiment, the lead-out position of the diversion section 232 is close to the edge of the glass backplane 300.

[0061] In this embodiment, the leading-out position of the drainage section 232 is close to the edge of the glass backplane 300, which can make full use of the edge space of the glass backplane 300; avoid interference with the internal components of the perovskite battery module, and contribute to improving the space utilization rate of the perovskite battery module. Moreover, the leading-out position close to the edge of the glass backplane 300 makes it easier for the drainage section 232 to be connected to an external circuit, facilitating the introduction or extraction of the external circuit, and reducing the length and complexity of the connection lines.

[0062] As Figure 8 , Figure 9 shown, in one embodiment, the leading-out position of the drainage section 232 is on the side away from the edge of the glass backplane 300.

[0063] In this embodiment, setting the leading-out position of the drainage section 232 on the side away from the edge of the glass backplane 300 can reduce the interference of the external environment on the drainage section 232, such as mechanical collision, dust accumulation, humidity change, etc.; effectively improve the stability of the perovskite battery module; at the same time, the drainage section 232 faces away from the edge of the glass backplane 300, which can increase the distance between the drainage section 232 and the edge of the glass backplane 300, thereby ensuring the electrical safety distance and enabling the opening position of the leading-out hole 310 to be closer to the edge of the glass backplane 300.

[0064] In one embodiment, in the length direction of the conductive strip 240, the leading-out hole 310 is opened at any position on the glass backplane 300.

[0065] In this embodiment, opening the leading-out hole 310 at any position on the glass backplane 300 can flexibly select the position of the leading-out hole 310 on the glass backplane 300 according to specific requirements and actual situations, providing greater design freedom for the layout and connection of the perovskite battery 200 module, and meeting the requirements of different application scenarios. For example, setting the leading-out hole 310 at a position close to the edge of the perovskite battery 200 for easy connection to an external circuit; or setting the leading-out hole 310 in the central area of the perovskite battery to achieve a more uniform current distribution or meet specific installation requirements, etc. By opening the leading-out hole 310 at any position in the length direction of the conductive strip 240, the requirements of various different application scenarios can be met.

[0066] In one embodiment, it further includes a sealant 400. The sealant 400 is disposed between the glass front plate 100 and the glass backplane 300, and the sealant 400 is disposed in the edge area of the glass front plate 100 and the glass backplane 300. The glass front plate 100, the glass backplane 300, and the sealant 400 jointly form a sealed cavity for sealing the perovskite battery 200.

[0067] In this embodiment, the sealant can be butyl rubber; the butyl rubber is disposed between the glass front plate 100 and the glass back plate 300, and is disposed in the edge region of the glass front plate 100 and the glass back plate 300, that is, the butyl rubber is disposed on the clear edge region of the glass front plate 100, so as to fill the gap between the glass front plate 100 and the glass back plate 300, ensuring that impurities such as moisture and oxygen in the external environment do not enter the interior of the perovskite battery 200 assembly. The glass front plate 100, the glass back plate 300 and the sealant 400 together form a sealing cavity for sealing the perovskite battery 200, which can effectively prevent impurities such as moisture and dust in the external environment from entering the interior of the perovskite battery 200 assembly, thereby protecting the perovskite battery 200 and the like from being damaged, effectively improving the reliability and stability of the perovskite battery 200 assembly, and extending its service life.
