Description

Technical Field

[0001] This utility model belongs to the technical field of equipment for testing batteries, and specifically relates to a perovskite solar cell test box. Background Technology

[0002] In the research and development of perovskite solar cells, testing unencapsulated cells is a crucial step in gaining a deeper understanding of cell performance and optimizing the fabrication process. Encapsulated cells are affected by encapsulation materials such as glass and encapsulating films, making it difficult to accurately reflect the intrinsic characteristics of the perovskite active layer, electrodes, and transport layer. Unencapsulated cells, on the other hand, allow for direct measurement of core parameters such as light absorption, carrier mobility, and defect state density, helping researchers accurately grasp material performance. By comparing cell performance under different annealing temperatures, solution formulations, and interface layer designs, microscopic problems such as thin-film pinholes and interface defects can be clearly exposed, thereby optimizing the fabrication process. Furthermore, unencapsulated cells can quickly reveal the degradation mechanisms of cells caused by environmental factors such as humidity, oxygen, light, and temperature, providing important evidence for developing efficient encapsulation technologies.

[0003] When testing unencapsulated perovskite solar cells, it is crucial to prioritize environmental control and mitigate potential risks. Perovskite materials are extremely sensitive to moisture and oxygen; even trace amounts of water or oxygen intrusion can trigger material decomposition, leading to a sharp decline in cell performance. Therefore, testing must be conducted in an inert gas environment such as nitrogen or argon to isolate the cells from external water and oxygen interference. Simultaneously, environmental humidity and temperature must be strictly controlled to ensure the accuracy and reliability of test data. Furthermore, perovskite materials often contain lead, and leakage could pose a threat to the environment and human health. Strict protective measures must be implemented during testing to prevent lead contamination.

[0004] Given the aforementioned testing requirements, test chambers for unencapsulated perovskite solar cells need to possess multiple functions. The test chamber should have an efficient inert gas replacement and circulation system capable of quickly establishing and maintaining a stable inert gas environment. Simultaneously, the test chamber must also have excellent sealing and lead leakage protection design, with built-in filtration and adsorption devices to promptly handle any lead-containing gases or particles that may be generated, avoiding the risk of lead leakage and ensuring safe and accurate testing of unencapsulated perovskite solar cells.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments thereof.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0049] Example 1

[0050] like Figure 1 , Figure 2 and Figure 3As shown, a perovskite solar cell test box of this utility model includes a test frame. A sealed light chamber 8 and a spectral monitoring module 1 are respectively arranged on the top of the test frame. A solar simulator 9 is arranged inside the sealed light chamber 8. A battery stage 10 is arranged below the solar simulator 9. The probe of the battery stage 10 is connected to the source meter. An activated carbon adsorption box 2 and a lead leakage monitoring box 7 are detachably installed on the inner wall of the sealed light chamber 8. An air exhaust port 6 is opened on the top of the sealed light chamber 8. A hydrogen inlet port 5 is opened on the bottom of the sealed light chamber 8. The hydrogen inlet port 5 is connected to an air pump 3 arranged below the test frame. The air pump 3 is connected to a hydrogen cylinder 4.

[0051] In actual use, the cell stage 10 has four probes: F+ probe, S+ probe, F- probe, and S- probe. An unencapsulated perovskite solar cell is placed on the cell stage 10. One end of the F+ probe is connected to the FORCE HI terminal of the source meter, and the other end is connected to the edge of the positive terminal of the cell. One end of the S+ probe is connected to the SENSE HI terminal of the source meter, and the other end is connected to the positive terminal of the cell. One end of the F- probe is connected to the FORCE LO terminal of the source meter, and the other end is connected to the edge of the negative terminal of the cell. One end of the S- probe is connected to the SENSE LO terminal of the source meter, and the other end is connected to the negative terminal of the cell.

[0052] The solar simulator 9 is used to simulate sunlight of different intensities and spectral distributions, providing perovskite solar cells with illumination conditions similar to real sunlight, thereby accurately testing the photoelectric conversion performance of unencapsulated perovskite solar cells under different illumination environments.

[0053] The spectral monitoring module 1 is located on one side of the exterior of the sealed light box 8. It is used to detect spectral differences caused by changes in the molecular structure of perovskite materials due to phase transitions or decomposition, and to monitor perovskite phase transitions or decomposition in real time. The detection results are then fed back to the terminal 32, providing a reliable spectral basis for battery performance testing.

[0054] The activated carbon adsorption box 2 is placed on the inner wall of the sealed light box 8. The interior is filled with sulfur-containing activated carbon. The sulfur-containing activated carbon reacts chemically with lead ions to generate lead sulfide. The reaction is fast and the lead removal efficiency is high. It can effectively adsorb lead ions that may be generated during the test, prevent lead ions from escaping, and ensure the safety of the test environment.

[0055] The lead leak monitoring box 7 is installed on the inner wall of the sealed light-exposed box 8. It contains moistened lead test paper and can monitor for lead leaks in real time. Once the lead test paper changes color, a lead leak is confirmed, allowing for timely protective measures. It should be noted that the moistened lead test paper refers to test paper soaked in dithizone solution. Dithizone forms a red complex with lead ions, turning the test paper red or pink.

[0056] The air vent 6, hydrogen inlet 5, air pump 3, and hydrogen cylinder 4 work together. When the air pump 3 is turned on, it draws hydrogen from the hydrogen cylinder 4 and injects it into the sealed light box 8 through the hydrogen inlet 5. The hydrogen rises, and the original air in the sealed light box 8 is discharged through the air vent 6. This adjusts the concentration of inert gas in the sealed light box 8 in real time, forming a stable inert gas protective atmosphere around the perovskite solar cell, isolating oxygen and moisture, preventing the perovskite from degrading during the test, and ensuring the reliability and accuracy of the test results.

[0057] Before the experiment begins, turn on the air pump 3. The air pump 3 draws hydrogen from the hydrogen cylinder 4 and injects it into the sealed light box 8 through the hydrogen inlet 5. The hydrogen rises, and the air originally inside the sealed light box 8 is expelled through the air vent 6. Light a small wooden stick and place it at the air vent 6. If you hear a "pop" sound and the flame is relatively calm, it means that the air inside the sealed light box 8 has been mostly expelled; if you hear a sharp popping sound, it means that the hydrogen is impure and there is still air remaining inside the sealed light box 8.

[0058] After the air has been purged, the battery to be tested is placed on the battery stage 10 of the sealed illumination chamber 8. The activated carbon adsorption box 2 and the lead leakage monitoring box 7 are then adsorbed onto the inner wall of the sealed illumination chamber 8. The air pump 3 is then turned off, and a sealing plug is inserted into the air vent 6 to maintain an inert gas environment within the sealed illumination chamber 8. The battery to be tested refers to an unencapsulated perovskite solar cell.

[0059] Then, turn on the solar simulator 9, adjust the parameters of the solar simulator 9, and the source meter applies an electrical signal to the battery under test through the probe and receives its electrical response.

[0060] During the test, the spectral monitoring module 1 detects the spectral differences caused by changes in the molecular structure of the perovskite material due to phase transitions or decomposition; the activated carbon adsorption box 2 adsorbs lead ions that may be generated during the test; and the lead test paper in the lead leakage monitoring box 7 is used to qualitatively indicate the presence of lead. If the lead test paper changes color, the experiment can be stopped or the experimenters can be alerted to strengthen their protective measures.

[0061] In one possible embodiment, an existing solar simulator testing system is used, including a solar simulator 9, a source meter, and a temperature control station. The solar simulator 9 is a Sciencetech SF300 model, the source meter is a Keithley 4200-SCS model, and the temperature control station is an MTI Corporation Glovebox Hotplate model. The battery platform 10 is an EverBeing EB-PS4 model. One end of the USB cable is connected to the USB port on the back of the source meter, and the other end is connected to the USB port of the terminal 32.

[0062] In this embodiment, as Figure 4 As shown, the spectral monitoring module 1 includes a mounting bracket 15 and a spectral monitoring probe 11 detachably connected to the mounting bracket 15. A hollow mounting box 16 is fixedly connected to the mounting bracket 15. A first microprocessor 12 that communicates with the spectral monitoring probe 11 is disposed inside the hollow mounting box 16. The first microprocessor 12 is connected to a first communication module 13.

[0063] In practical use, the spectral monitoring module 1 is located on one side of the exterior of the sealed illumination box 8, and the spectral monitoring probe 11 is either an infrared probe or a Raman spectral probe. The infrared probe, based on the absorption characteristics of molecules to infrared light, can sensitively capture the differences in infrared absorption spectra caused by changes in the molecular structure of perovskite materials due to phase transitions or decomposition. The Raman probe utilizes the principle of inelastic scattering of photons and molecules, analyzing the changes in the position, intensity, and width of characteristic peaks in the Raman scattering spectrum to determine the evolution of the perovskite material's crystal structure and changes in its chemical composition. Both the infrared probe and the Raman spectral probe can be used to monitor phase transitions or decomposition in perovskite, and transmit the spectral data to the terminal 32 via the first microprocessor 12 and the first communication module 13, providing researchers with crucial information for timely adjustment of test conditions and optimization of battery performance.

[0064] In this embodiment, a slide rail is provided on the top of the test frame, and the slide rail is arranged along the length of the sealed light box 8. A slider adapted to the slide rail is provided at the bottom of the mounting frame 15.

[0065] Since the signal strength of infrared and Raman probes is distance-dependent, the infrared or Raman spectroscopy probe can be set by sliding the mounting bracket 15 to change its relative position with the sealed light box 8. This ensures that the infrared or Raman spectroscopy probe is always at the optimal working distance and avoids a decrease in the data signal-to-noise ratio due to the displacement of the battery sample position.

[0066] In this embodiment, as Figure 1 and Figure 8 As shown, a terminal 32 is placed on top of the test rack. Terminal 32 has a main control communication module 31, which is communicatively connected to the first communication module 13. Terminal 32 is also communicatively connected to the source meter. In actual use, terminal 32 is used to receive data from the source meter and the spectral monitoring module 1. Terminal 32 is connected to the source meter via a USB data cable, and terminal 32 is connected to the spectral monitoring module 1 via the main control communication module 31 and the first communication module 13. Terminal 32 is a computer, and both the main control communication module 31 and the first communication module 13 are Bluetooth modules.

[0067] In this embodiment, as Figure 5As shown, the lead leak monitoring box 7 has a hollow structure. Lead test paper is placed inside the lead leak monitoring box 7, and a first suction cup 25 is installed on the back of the box. The lead test paper refers to test paper soaked in dithizone solution. Dithizone forms a red complex with lead ions, turning the test paper red or pink.

[0068] In this embodiment, as Figure 6 As shown, the activated carbon adsorption box 2 has a hollow structure, and sulfur-containing activated carbon is placed inside the activated carbon adsorption box 2. A second suction cup 21 is installed on the back of the activated carbon adsorption box 2. The sulfur-containing activated carbon reacts chemically with lead ions to form lead sulfide. The reaction is fast and the lead removal efficiency is high. It can effectively adsorb lead ions that may be generated during the test, prevent lead ion escape, and ensure the safety of the test environment.

[0069] In this embodiment, a pressure gauge and a regulating valve are installed at the inlet of the gas pump 3. The gas pump 3 is a diaphragm pump or vortex pump specifically for hydrogen. The hydrogen inlet flow rate is adjusted by the regulating valve.

[0070] In this embodiment, the hydrogen inlet 5 and the air outlet 6 are located diagonally across the three-dimensional space of the sealed light-emitting chamber 8. This diagonal layout ensures that hydrogen enters from one corner of the sealed light-emitting chamber 8, while air exits from the furthest diagonal, forming the longest gas flow path. This prevents hydrogen from flowing directly to the nearest outlet without fully replacing the air, reduces dead zones in the gas flow, improves replacement purity, and allows the air inside the chamber to be more thoroughly expelled.

[0071] Example 2

[0072] like Figure 7 , Figure 9 and Figure 10 As shown, unlike Embodiment 1, in this embodiment, a receiving box 33 is provided on one side of the battery stage 10. The receiving box 33 includes a first sub-compartment 331 and a second sub-compartment 332. The first sub-compartment 331 is used to place untested battery samples, and the second sub-compartment 332 is used to place untested battery samples. In one possible embodiment, the inner wall of the receiving box 33 is provided with a light-shielding layer and a heat-insulating layer. The lid of the receiving box 33 is magnetically sealed to the box body, and a silicone sealing strip is added to the edge to prevent light from seeping in through gaps.

[0073] Operators can place multiple battery samples at once, reducing the frequency of opening and closing the door 36 of the sealed light chamber 8 and minimizing external environmental interference. During testing, untested batteries can be removed sequentially from the first sub-cell 331 and immediately placed into the second sub-cell 332 after testing, significantly improving the efficiency of batch testing while ensuring safety.

[0074] A window 37 is provided on the side of the sealed light box 8 near the battery platform 10. A sleeve 38 is sealed and connected inside the window 37, and a protective glove 34 is fixed on the sleeve 38. In one possible embodiment, the protective glove 34 is adhered to the sleeve 38, and the window 37 is sealed and connected to the sleeve 38.

[0075] The sealed connection between the protective glove 34 and the sleeve 38 effectively prevents lead dust or other harmful substances from leaking out of the sealed light exposure chamber 8, protecting operators from contamination. Furthermore, battery samples can be handled, adjusted, or tested without frequently opening the door 36 of the sealed light exposure chamber 8, improving work efficiency.

[0076] The above description is merely an embodiment of this utility model and is not intended to limit this utility model in any way. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
