However, despite achieving photoelectric conversion efficiency of over 26% under laboratory conditions, the long-term stability of perovskite solar cells in practical applications remains one of the main obstacles to their commercialization. To evaluate the durability and stability of perovskite cells in practical applications, rigorous aging tests are particularly important.

[0003] A Chinese patent discloses an aging detection device for perovskite solar cells (authorization announcement number CN219659674U). This patented technology can stably clamp and fix solar cells of various sizes when conducting aging detection, thus improving the detection efficiency.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing testing devices are insufficient in terms of portability and protection. Although these devices can perform basic testing tasks, they often lack a compact design, making them inconvenient to carry to outdoor or mobile testing environments. Furthermore, their adaptability to testing environments and the protection mechanisms of the batteries themselves are limited. For example, they cannot effectively cope with severe weather conditions or abnormal situations during the testing process, thereby affecting the flexibility, efficiency, and safety of the test. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology lacks adaptability to environmental changes and protection against potential risks during the testing process. To address this, we propose a perovskite solar cell aging detection device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a perovskite solar cell aging detection device, comprising a protective box, a detection device body slidably connected inside the protective box, a top plate fixedly connected to the top of the detection device body, handles fixedly connected to both sides of the top of the top plate, straight grooves formed on both sides of the detection device body, slots formed at the front end of the straight grooves, adjustment grooves formed on both sides of the front end of the protective box, a through groove formed on the side of the adjustment groove near the detection device body, an adjustment block slidably connected inside the adjustment groove, and an insert block fixedly connected to the side of the adjustment block near the detection device body.

[0007] Preferably, the size of the insert is adapted to the size of the slot, and the surface of the insert is inserted into the interior of the slot.

[0009] Preferably, guide grooves are provided at both ends of the adjustment groove, and guide blocks are fixedly connected to both ends of the adjustment block, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0010] Preferably, two energy storage springs are fixedly connected to the rear end of the adjustment groove, and the front end of the energy storage springs is fixedly connected to the rear end of the adjustment block.

[0011] Preferably, a return spring is fixedly connected to both sides of the bottom of the protective box, a push block is fixedly connected to the top of the return spring, and a limit block is fixedly connected to both ends of the push block.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a perovskite solar cell aging detection device, including a protective box 1, a detection device body 2 slidably connected inside the protective box 1, a top plate 3 fixedly connected to the top of the detection device body 2, handles 4 fixedly connected to both sides of the top of the top plate 3, straight grooves 5 on both sides of the detection device body 2, slots 6 at the front end of the straight grooves 5, adjustment grooves 8 on both sides of the front end of the protective box 1, through grooves 9 on the side of the adjustment grooves 8 closest to the detection device body 2, and sliding connections within the adjustment grooves 8... An adjusting block 11 is attached, and an insert block 10 is fixedly connected to the side of the adjusting block 11 near the main body 2 of the testing device. The operator pushes the adjusting block 11 into the adjusting groove 8, so that the adjusting block 11 moves the insert block 10 and moves the insert block 10 into the straight groove 5, so that the insert block 10 is released from the limit between the insert block 10 and the slot 6. At the same time, the limit of the main body 2 of the testing device is also released. When the battery needs to be tested, the operator lifts the top plate 3 to expose the main body 2 of the testing device to the outside, so as to avoid damage to the main body 2 of the testing device when it is not in use.

[0021] Reference Figure 2 and Figure 4 As shown in this embodiment: the size of the insert 10 is adapted to the size of the slot 6, and the surface of the insert 10 is inserted into the interior of the slot 6. By adapting the size of the insert 10 to the size of the slot 6, the insert 10 can be stably inserted into the interior of the slot 6, thereby increasing the stability of the detection device body 2 during use, preventing the detection device body 2 from shaking or shifting, and improving the applicability and reliability of the device. At the same time, the insertion and engagement method between the insert 10 and the slot 6 makes it easy for the user to limit and fix the detection device body 2, simplifying the operation process.

[0022] Reference Figure 1 As shown in this embodiment, the protective box 1 is made of high-strength polyethylene. By using high-strength polyethylene as the material for the protective box 1, it has high strength and wear resistance, can withstand greater external forces and friction, and extends the service life of the device. At the same time, high-strength polyethylene also has good corrosion resistance and aging resistance, can maintain stable performance in harsh environments, and is not easily damaged by environmental factors. In addition, the use of high-strength polyethylene as the material for the protective box 1 also makes the overall weight of the device lighter, making it easier to carry and transport, and improving the portability and flexibility of the device.

[0023] Reference Figure 4 As shown in this embodiment: guide grooves 12 are provided at both ends of the adjusting groove 8, and guide blocks 13 are fixedly connected to both ends of the adjusting block 11. The surface of the guide block 13 is slidably connected to the inside of the guide groove 12. When the operator moves the adjusting block 11, the adjusting block 11 drives the guide block 13 to slide inside the guide groove 12. Through the above settings, the stability of the movement of the adjusting block 11 is effectively improved, and the phenomenon of deviation or shaking of the adjusting block 11 during the movement is avoided, thereby ensuring the stability and reliability of the overall structure. At the same time, the sliding connection design between the guide block 13 and the guide groove 12 also makes the movement of the adjusting block 11 smoother, reduces frictional resistance, and improves the efficiency of use.

[0024] Reference Figure 4 As shown in this embodiment: two energy storage springs 14 are fixedly connected to the rear end of the adjustment groove 8. The front end of the energy storage springs 14 is fixedly connected to the rear end of the adjustment block 11. When the operator pushes the adjustment block 11 into the adjustment groove 8, the adjustment block 11 compresses the energy storage springs 14 to store energy, and drives the insertion block 10 to release the limit between itself and the slot 6. After the operator adjusts the appropriate position of the detection device body 2, the adjustment block 11 is released. Under the action of the rebound force of the energy storage springs 14, the adjustment block 11 quickly resets and drives the insertion block 10 to re-engage in the slot 6, thereby fixing the position of the detection device body 2.

[0025] Reference Figure 2 As shown in this implementation scheme: both sides of the bottom of the protective box 1 are fixedly connected to a return spring 15, the top of the return spring 15 is fixedly connected to a push block 16, and both ends of the push block 16 are fixedly connected to a limit block 18. When the operator moves the detection device body 2 downward, the detection device body 2 pushes the push block 16 to compress the return spring 15 to store force. When the operator releases the limit of the detection device body 2, the push block 16 quickly resets under the action of the return spring 15 and drives the detection device body 2 to rise, which facilitates the operator to quickly deploy the equipment.

[0026] Reference Figure 2As shown in this embodiment: sliders 17 are provided at both ends inside the protective box 1, and sliding grooves 7 are fixedly connected to both ends of the detection device body 2. The surface of the sliding groove 7 is slidably connected to the inside of the slider 17. When the operator moves the detection device body 2 up and down, the detection device body 2 drives the sliding groove 7 to slide inside the slider 17. Through the above settings, the movement of the detection device body 2 is more stable, avoiding shaking or deviation of the detection device body 2 during movement, improving the stability and effectiveness of the equipment. At the same time, the sliding connection design between the sliding groove 7 and the slider 17 also makes the movement of the detection device body 2 smoother, reduces the resistance during movement, and makes the operation simpler.

[0027] The operator pushes the adjusting block 11 into the adjusting groove 8, causing the adjusting block 11 to move the insert block 10 into the straight groove 5. This releases the limiting position between the insert block 10 and the slot 6, and simultaneously releases the limiting position of the detection device body 2. When the battery needs to be tested, the operator raises the top plate 3, exposing the detection device body 2 to the outside, preventing external damage when not in use. The matching size of the insert block 10 to the slot 6 ensures that the insert block 10 can be securely inserted into the slot 6, increasing the stability of the detection device body 2 during use, preventing shaking or displacement, and improving the practicality and reliability of the device. The insertion and engagement between the insert block 10 and the slot 6 facilitates the user's positioning and fixing of the detection device body 2, simplifying the operation process. The protective box 1, made of high-strength polyethylene, possesses high strength and wear resistance, capable of withstanding significant external forces and friction, extending the device's service life. Furthermore, high-strength polyethylene exhibits excellent corrosion resistance and aging resistance, maintaining stable performance even in harsh environments and resisting damage from environmental factors. Additionally, the use of high-strength polyethylene in the protective box 1 reduces the overall weight of the device, making it easier to carry and transport, thus improving its portability and flexibility. When the operator moves the adjusting block 11, the adjusting block 11 drives the guide block 13. Sliding within the guide groove 12, the above-mentioned design effectively improves the stability of the adjustment block 11's movement, preventing deviation or wobbling during movement, thus ensuring the stability and reliability of the overall structure. Simultaneously, the sliding connection design between the guide block 13 and the guide groove 12 makes the movement of the adjustment block 11 smoother, reducing frictional resistance and improving efficiency. When the operator pushes the adjustment block 11 into the adjustment groove 8, the adjustment block 11 compresses the storage spring 14 to store force, causing the insertion block 10 to release its limit from the slot 6. After the operator adjusts the appropriate position of the detection device body 2, the adjustment block 11 is released. Under the rebound force of the storage spring 14, the adjustment block 11... The device quickly resets and causes the insertion block 10 to re-engage in the slot 6, thus fixing the position of the detection device body 2. When the operator moves the detection device body 2 downwards, the detection device body 2 pushes the push block 16 to compress the return spring 15 and store force. When the operator releases the limit of the detection device body 2, the push block 16 quickly resets under the action of the return spring 15, causing the detection device body 2 to rise, facilitating rapid deployment of the equipment. When the operator moves the detection device body 2 up and down, the detection device body 2 causes the slide groove 7 to slide inside the slider 17. Through the above settings, the movement of the detection device body 2 is more stable, preventing the detection device body 2 from shaking or shifting during movement.This design improves the stability and performance of the equipment. Furthermore, the sliding connection between the slide groove 7 and the slider 17 allows for smoother movement of the detection device body 2, reducing resistance during movement and simplifying operation.
