Description

Technical Field

[0001] This utility model relates to the technical field of perovskite solution storage equipment, and more specifically, to a storage container for perovskite solution. Background Technology

[0002] Perovskite photovoltaic technology has made significant progress in recent years, especially in the deposition of perovskite thin films using inkjet printing. Lead halide perovskite materials exhibit excellent photoelectric properties and have become a research hotspot in the field of next-generation solar cells. The preparation of perovskite thin films mainly employs slot coating and inkjet printing methods, both of which require perovskite solutions as ink. However, perovskite materials are extremely sensitive to water and oxygen, which has become a major obstacle to the large-scale application of perovskite photovoltaic technology.

[0003] Currently, to protect perovskite solutions from the corrosive effects of moisture and oxygen, related technologies typically employ the construction of drying chambers. These chambers control humidity and oxygen levels to provide a dry environment for the perovskite solutions. While this strategy effectively protects the properties of perovskite materials, it is costly and requires continuous maintenance and energy consumption. This significantly limits the commercialization of perovskite photovoltaic technology, especially in the context of pursuing low-cost mass production.

[0004] Therefore, there is an urgent need for a device that can significantly reduce costs and effectively prevent water and oxygen from corroding perovskite solutions. Utility Model Content

[0005] The main objective of this invention is to provide a storage container for perovskite solutions to solve the problems of difficulty in storing perovskite solutions and high storage costs in the prior art.

[0006] To achieve the above objectives, this utility model provides a storage container for a perovskite solution, comprising: a storage bottle having a storage space containing a perovskite solution; a first pipe, one end of which is located within the storage space, for conveying the perovskite solution in the storage space to an ink output device; a second pipe, one end of which is located within the storage space, for conveying an inert gas into the storage space; and a water-absorbing component, a portion of which is located within the storage space and above the perovskite solution, for absorbing moisture from the air inside the storage bottle.

[0007] Furthermore, the first pipe is closer to the central axis of the storage bottle than the second pipe.

[0008] Furthermore, the first conduit includes: a pipe body, one end of which is located within the storage space; and a filter assembly disposed at the end of the pipe body located within the storage space.

[0009] Furthermore, the filtering assembly includes a filter screen.

[0010] Furthermore, the water absorption assembly includes: a water absorption section located inside the storage bottle; and an adjustment member connected to the water absorption section, with a portion of the adjustment member located inside the storage bottle. The adjustment member is used to adjust the position of the water absorption section inside the storage bottle so that the water absorption section is spaced apart from the perovskite solution.

[0011] Furthermore, the absorbent part includes: a receiving bag having a receiving space and a plurality of through holes communicating with the receiving space; and absorbent material disposed within the receiving space.

[0012] Furthermore, the absorbent material includes at least one of silica gel and activated alumina.

[0013] Furthermore, the storage bottle includes: a bottle cap having a first through hole and a second through hole spaced apart, a first pipe passing through the first through hole and a second pipe passing through the second through hole; a bottle body having a storage space and an opening communicating with the storage space, with the bottle cap covering the opening; and a sealing element disposed at the connection between the bottle cap and the bottle body.

[0014] Furthermore, the port at one end of the first pipe located within the storage space is located below the port at one end of the second pipe located within the storage space.

[0015] Furthermore, the storage container for the perovskite solution also includes a control valve, which is located on the second pipeline and outside the storage space.

[0016] According to the technical solution of this utility model, the storage container for the perovskite solution includes a storage bottle, a first pipe, a second pipe, and a water-absorbing component. The storage bottle has a storage space containing the perovskite solution. One end of the first pipe is located within the storage space and is used to transport the perovskite solution in the storage space to an ink output device. One end of the second pipe is located within the storage space and is used to supply inert gas into the storage space. A portion of the water-absorbing component is located within the storage space and is positioned above the perovskite solution. The water-absorbing component is used to absorb moisture from the air inside the storage bottle.

[0017] By incorporating a water-absorbing component within the storage bottle and utilizing a second conduit to deliver inert gas, the technical challenge of perovskite solutions being susceptible to corrosion from atmospheric water and oxygen during storage and transportation has been addressed. The storage bottle contains the perovskite solution, with one end of a first conduit extending into the storage space to deliver the solution to the ink dispensing device for precise ink distribution. A second conduit also extends into the storage space to introduce an inert gas, such as nitrogen or argon, to isolate it from atmospheric oxygen and moisture, reducing their corrosive effects on the perovskite solution. A portion of the water-absorbing component is located within the storage space, above the perovskite solution, effectively absorbing moisture from the air within the storage bottle, further mitigating the risk of water-oxygen corrosion. This design makes the storage and transportation of the perovskite solution more stable, avoiding performance degradation caused by moisture exposure, thereby contributing to improved battery conversion efficiency and reducing the cost of large-scale, low-cost mass production of perovskite photovoltaic technology.

[0025] To address the problems of difficulty in storing perovskite solutions and high storage costs in existing technologies, this invention provides a storage container for perovskite solutions.

[0026] like Figure 1 As shown, the storage container for the perovskite solution includes a storage bottle 10, a first pipe 20, a second pipe 30, and a water-absorbing assembly 40. The storage bottle 10 has a storage space 11, which stores the perovskite solution. One end of the first pipe 20 is located inside the storage space 11, and the first pipe 20 is used to transport the perovskite solution in the storage space 11 to the ink output device. One end of the second pipe 30 is located inside the storage space 11, and the second pipe 30 is used to supply inert gas into the storage space 11. A portion of the water-absorbing assembly 40 is located inside the storage space 11, and the water-absorbing assembly 40 is located above the perovskite solution. The water-absorbing assembly 40 is used to absorb moisture from the air inside the storage bottle 10.

[0027] By incorporating a water-absorbing component 40 within the storage bottle 10 and utilizing a second pipe 30 to deliver inert gas, the technical problem of perovskite solutions being susceptible to corrosion from airborne water and oxygen during storage and transportation is solved. The storage space 11 of the storage bottle 10 contains the perovskite solution. One end of the first pipe 20 extends into the storage space 11 to deliver the perovskite solution to the ink dispensing device, enabling precise ink distribution. The second pipe 30 also extends into the storage space 11 to fill it with an inert gas, such as nitrogen or argon, to isolate it from oxygen and moisture in the air, reducing their corrosive effects on the perovskite solution. A portion of the water-absorbing component 40 is located within the storage space 11 and above the perovskite solution, effectively absorbing moisture from the air within the storage bottle 10, further reducing the risk of water-oxygen corrosion. This design makes the storage and transportation of the perovskite solution more stable, avoiding performance degradation caused by moisture exposure, thereby contributing to improved battery conversion efficiency and reducing the cost of large-scale, low-cost mass production of perovskite photovoltaic technology.

[0028] It should be noted that the inert gas being transported includes at least one of nitrogen and argon.

[0029] Alternatively, the ink output device may be part of a slot coating device or an inkjet printing device; no specific limitation is made here.

[0030] In some alternative embodiments, please refer to Figure 1 The first pipe 20 is positioned closer to the central axis of the storage bottle 10 than the second pipe 30. This design allows the inert gas to be more evenly distributed throughout the top space of the container, effectively forming a protective layer that isolates the perovskite solution from moisture and oxygen in the outside air. Precise pipe positioning ensures that the inert gas quickly fills the upper gaps when adding or removing the perovskite solution, reducing the chance of air intrusion and thus lowering the risk of degradation during storage and use. Furthermore, this layout optimizes the use of space inside the container, allowing the dehydration material container to be better positioned on the container sidewall, improving its drying efficiency and ensuring that the internal environment remains at a suitable low humidity level, which is beneficial for the long-term stable storage and efficient use of the perovskite solution. In other embodiments not shown in the figures, the relative positions of the pipes and the internal structure of the container can be further adjusted according to actual needs to accommodate containers of different capacities and shapes, enhancing the system's applicability and flexibility.

[0031] In some alternative embodiments, please refer to Figure 1 The first conduit 20 includes a tube body 21 and a filter assembly 22. One end of the tube body 21 is located within the storage space 11; the filter assembly 22 is disposed at the end of the tube body 21 located within the storage space 11. In this embodiment, the structure of the first conduit 20 is further refined, including the tube body 21 and the filter assembly 22. One end of the tube body 21 extends into the storage space 11, while the filter assembly 22 is disposed at this end of the tube body 21. The combination of the tube body 21 and the filter assembly 22 provides an additional protective layer for the ink output device, reducing impurities in the perovskite solution delivered to the ink output device. The porous structure of the filter assembly 22 can effectively intercept small particles, ensuring the purity of the perovskite solution. At the same time, its physical properties also help to further absorb residual moisture, enhancing the drying effect of the entire system. This design not only improves the storage safety of the perovskite solution but also ensures high-quality output during the printing process, reducing equipment failures and battery performance degradation caused by perovskite solution contamination.

[0032] In some alternative embodiments, the filter assembly 22 includes a filter screen. Specifically, the filter assembly 22 is designed with a filter screen that effectively intercepts any impurity particles that may enter the inkjet printhead with the ink, ensuring ink purity and print quality. The material and pore size of the filter screen must be carefully selected to suit the characteristics of the perovskite solution, preventing ink clogging while ensuring efficient filtration.

[0033] In some alternative embodiments, please refer to Figure 1The water-absorbing assembly 40 includes a water-absorbing part 41 and an adjusting member 42. The water-absorbing part 41 is located inside the storage bottle 10. The adjusting member 42 is connected to the water-absorbing part 41, and a portion of the adjusting member 42 is located inside the storage bottle 10. The adjusting member 42 is used to adjust the position of the water-absorbing part 41 within the storage bottle 10, so that the water-absorbing part 41 is spaced apart from the perovskite solution. The structural design of the water-absorbing assembly 40 further enhances the moisture-proof performance of the dedicated container. The water-absorbing part 41, placed inside the storage bottle 10, effectively removes moisture from the air inside the bottle through physical adsorption. The adjusting member 42 is connected to the water-absorbing part 41 and partially placed inside the storage bottle 10. Its function is to dynamically adjust the position of the water-absorbing part 41, ensuring that it is spaced apart from the perovskite solution, avoiding potential chemical reactions or contamination from direct contact. This design allows the absorbent section 41 to operate effectively in areas far from the ink while maintaining a dry environment inside the container. This reduces the corrosive effects of airborne moisture and oxygen on the perovskite solution, providing a relatively enclosed, low-humidity storage space without the need for large drying equipment. This helps maintain the stability of the perovskite solution and extends its service life. The dynamic position adjustment function of the regulating element 42 also ensures that the absorbent section 41 can adjust according to changes in the ink level inside the container, maintaining optimal absorbency and effect, and further optimizing the container's moisture-proof and oxygen-resistant properties.

[0034] In some alternative embodiments, please refer to Figure 1 The absorbent portion 41 includes a receiving bag 411 and absorbent material 412. The receiving bag 411 has a receiving space and multiple through holes communicating with the receiving space; the absorbent material 412 is disposed within the receiving space. The structure of the absorbent portion 41 is further refined, including the receiving bag 411 and the absorbent material 412 located therein. The receiving bag 411 forms a space with multiple through holes, which allow gas flow but prevent the absorbent material 412 from escaping. The Teflon-made receiving bag 411 not only provides a physical barrier but also ensures compatibility with the perovskite solution, preventing any potential chemical reactions. The absorbent material 412, such as silica gel or activated alumina, resides inside the receiving bag 411, using its strong physical adsorption capacity to remove moisture from the storage bottle 10, creating a dry environment and significantly enhancing the protective effect on the perovskite solution. This design allows the storage bottle 10 to maintain a low humidity state continuously, effectively isolating moisture and oxygen in the air even during long-term storage or repeated use, reducing the risk of degradation of the perovskite material, thereby improving the performance and stability of the final product. Of course, the specific configuration and size of the absorbent part 41 can be adjusted and optimized according to actual needs to adapt to perovskite solutions of different capacities and types. By placing the absorbent material 412 in the containment bag 411, direct contact with the perovskite solution can be prevented, avoiding possible chemical reactions, while ensuring that the replacement and maintenance of the desiccant are more convenient. The absorbent material 412 inside the containment bag 411 can also be replaced periodically as needed.

[0035] In some alternative embodiments, the absorbent material 412 includes at least one of silica gel and activated alumina. These materials, such as silica gel and activated alumina, are effective at adsorbing and removing moisture from the environment inside the storage bottle 10.

[0036] In some alternative embodiments, please refer to Figure 1 The storage bottle 10 includes a cap 14, a bottle body 12, and a sealing element. The cap 14 has a first through hole and a second through hole spaced apart. A first pipe 20 passes through the first through hole, and a second pipe 30 passes through the second through hole. The bottle body 12 has a storage space 11 and an opening 13 communicating with the storage space 11. The cap 14 covers the opening 13. The sealing element is disposed at the connection between the cap 14 and the bottle body 12. In this embodiment, the storage bottle 10 includes a cap 14 and a bottle body 12, wherein the cap 14 has a first through hole and a second through hole for the first pipe 20 and the second pipe 30 to pass through, respectively. The bottle body 12 has a storage space 11 and an opening 13. The cap 14 tightly covers the opening 13, and the sealing element ensures the airtightness of the container. The first pipe 20 and the second pipe 30 allow the inert gas and perovskite solution to enter and exit the storage bottle 10 separately through the pipes. The use of a sealing element further enhances the sealing effect between the bottle cap 14 and the bottle body 12, effectively preventing external water and oxygen intrusion and protecting the internal perovskite solution. By creating an inert gas atmosphere and combining it with the application of dehydrating substances, the container of this invention can significantly reduce the cost of resisting water and oxygen intrusion into the perovskite solution without building a drying room, while avoiding performance degradation caused by moisture exposure, which is beneficial to improving the conversion efficiency and production efficiency of perovskite solar cells.

[0037] It should be noted that the storage bottle 10 also includes at least two sealing rings. The first pipe 20 passes through the first through hole and is sealed by a sealing ring. The second pipe 30 passes through the second through hole and is sealed by a sealing ring.

[0038] Optionally, the bottle cap 14, the first pipe 20, the second pipe 30, and the water-absorbing component 40 can be made of materials resistant to perovskite solution corrosion, such as Teflon. The bottle body 12 can be made of materials such as glass, ceramic, aluminum alloy, or Teflon.

[0039] In some alternative embodiments, the port of the first pipe 20 located within the storage space 11 is positioned below the port of the second pipe 30 located within the storage space 11. This layout design ensures that the inert gas can fully cover the liquid surface within the storage space, effectively isolating the perovskite solution from contact with water and oxygen in the air. Specifically, when the inert gas is injected into the storage space 11 through the second pipe 30, the gas naturally flows upward, forming a protective inert gas layer above the solution. Simultaneously, this gas flow pattern avoids agitation and splashing of the solution, reducing the generation of bubbles and ensuring the purity and stability of the solution. Furthermore, the lower position of the first pipe 20 facilitates the entry of the perovskite solution into the ink output device via the first pipe 20.

[0040] In some alternative embodiments, please refer to Figure 1 The storage container for the perovskite solution also includes a control valve 50, which is located on the second pipe 30 and outside the storage space 11. By installing the control valve 50 on the second pipe 30, the inflow of inert gas can be precisely managed, effectively maintaining the gas atmosphere inside the container and preventing the entry of water and oxygen from the air. This design ensures the stability of the perovskite solution during storage and transportation, reducing the impact of the external environment on the solution performance. Furthermore, the external location of the control valve 50 facilitates operation and monitoring, improving the convenience and safety of equipment use. This reduces the cost of preventing water and oxygen intrusion while ensuring the quality of the perovskite solution, which is beneficial for improving the performance and production efficiency of perovskite solar cells. Of course, in other embodiments not shown, the control valve 50 can also be adjusted in position or different types of valves can be used to meet specific process requirements and operating environments.

[0041] During use, the perovskite solution is first safely stored in the storage space 11 of the storage bottle 10. When ink needs to be delivered to the ink dispensing device, it is precisely delivered through the first pipe 20. At this time, the water-absorbing part 41 in the water-absorbing component 40 absorbs moisture from the air inside the storage bottle 10 through its multiple through-holes, while the regulating component 42 ensures that the water-absorbing part 41 and the perovskite solution maintain a certain distance to avoid direct contact. At the same time, the second pipe 30 delivers inert gas into the storage space 11. Through the regulation of the control valve 50, a suitable gas environment is maintained inside the container, ensuring that the inert gas fully covers the perovskite solution, forming an effective protective layer to isolate water and oxygen in the air. The filter component 22, especially the filter screen, further purifies the perovskite solution entering the first pipe 20, preventing impurities from entering the ink dispensing device. The entire process ensures the airtightness of the container through the seal between the bottle cap 14 and the bottle body 12, while the use of Teflon material ensures the corrosion resistance of all components to the perovskite solution. This design significantly reduces the risk of perovskite solution being corroded by water and oxygen in the air without the need for a drying room, providing key technical support for the industrial production of perovskite solar cells.
