Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic module testing, and relates to a perovskite battery module IV testing system and method for a production line. Background Art

[0002] Perovskite Solar Cells (PSCs), as an emerging third-generation solar cell technology, are gradually becoming the focus of global scientific research and industry due to their high efficiency, low cost and excellent flexibility. Since the debut of this technology in 2009, its photoelectric conversion efficiency (PCE) has achieved a leap from the initial 3.8% to more than 25% today. This achievement is close to the efficiency level of traditional silicon-based solar cells, indicating that perovskite solar cells have great potential in the field of energy conversion.

[0003] Currently, with the continuous deepening of scientific research and the continuous improvement of technology, perovskite solar cells are moving towards industrialization at an unprecedented speed. In this process, many companies dedicated to perovskite technology are vigorously promoting the construction of mass production lines in order to occupy a place in the fierce competition in the global energy market and jointly promote the commercialization of this emerging technology. However, on the road to the production line of perovskite cells, how to ensure that the production rhythm of each preparation link matches and achieve faster overall production efficiency has become a major problem.

[0004] Compared with crystalline silicon cells, perovskite cells present unique challenges in the power test grading stage. Due to the unique structural characteristics of perovskite cells, they cannot be tested with fast transient light sources, but must use steady-state light testing methods. This test method requires the continuous application of steady-state light source irradiation for a certain period of time to ensure the stability of the perovskite component in the power test. To make it more complicated, in order to fully evaluate the stability of the perovskite cell and the accuracy of the final power test, a period of MPPT (maximum power point tracking) testing is required.

[0005] MPPT testing is crucial for perovskite cells. It can help researchers and manufacturers gain a deeper understanding of the performance of cells under different lighting conditions, thereby optimizing the design and production process of cells. However, this testing process is relatively time-consuming, and has become the biggest bottleneck restricting the high-beat production of perovskite cells. How to shorten the test time and improve the test efficiency while ensuring the accuracy of the test has become a key issue that needs to be solved in the current industrialization process of perovskite solar cells.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1 An embodiment of the present invention provides an IV test system for a perovskite battery assembly for a production line, comprising a test lamp group 2 installed on a wall 1 of a production line workshop and a guide support assembly installed on the floor of the workshop; a perovskite battery assembly to be tested is installed on the upper side of the guide support assembly, and an mppt tracking device and an IV test source meter are installed on the guide support assembly; the mppt tracking device and the IV test source meter are both electrically connected to the perovskite battery assembly to be tested.

[0028] In this embodiment, the mppt tracking device is connected to the perovskite battery assembly to be tested, and can track the maximum power point of the perovskite solar cell. The IV test source meter and the test software system can perform an IV curve scan on the perovskite battery assembly, can collect data from the mppt tracking device, and can classify the IV curve data and mppt tracking data of the perovskite assembly to be tested, and control all operations of the entire perovskite battery assembly IV test system. While meeting the requirements of the IV precise test of the perovskite battery assembly, this embodiment can improve the IV test rhythm of the perovskite battery to match the rhythm of the front-end production of the perovskite battery, while saving energy and better integrating with the preparation workshop to optimize the space utilization of the workshop.

[0029] In a feasible embodiment of the present invention, the guide support assembly preferably adopts a slide rail 3; the speed of the slide rail 3 can be adjusted according to the test time of the perovskite assembly or the assembly production rhythm, and the upper side of the slide rail 3 has an assembly fixing device for fixing the perovskite battery assembly to be tested; the test lamp group 2 is distributed on the wall surrounded by the slide rail 3, and the height is not less than the height of the assembly installed on the slide rail 3. The test lamp group 2 includes a number of LED lamp beads that can emit different bands, and its comprehensive spectrum meets the AAA standard for the light source required for solar cell testing.

[0030] In this embodiment, the design of the slide rail 3 makes the movement of the perovskite battery component to be tested flexible and controllable. Its speed can be precisely adjusted according to the actual perovskite component test time or component production rhythm, thereby optimizing the test process and improving production efficiency. This adjustability ensures that the test process can meet both the accuracy requirements and the needs of different production rhythms, enhancing the flexibility and adaptability of the system. The component fixing device equipped on the upper side of the slide rail 3 can firmly fix the perovskite battery component to be tested, avoiding the test error caused by the shaking or displacement of the component during the test. This stable and reliable fixing method provides a strong guarantee for the accuracy and consistency of the test results. Secondly, the test light group 2 is cleverly distributed on the wall surrounded by the slide rail 3, and the height is not less than the height of the slide rail 3 installation component, ensuring that the light source can be evenly and fully irradiated on the component to be tested during the test. At the same time, the test light group contains LED lamp beads that can emit different bands, and its comprehensive spectrum meets the AAA standard required for the light source of the solar cell test, further improving the accuracy and reliability of the test.

[0031] The embodiment of the present invention discloses a method for IV testing of a perovskite battery component for a production line, based on the above-mentioned IV testing system for a perovskite battery component for a production line, comprising the following steps: S1, fix the perovskite battery components to be tested on the slide rail 3 in sequence; S2, turn on the test light group 2, connect it through the mppt tracking device, and track the maximum power point of the perovskite battery component to be tested; In this step, the MPPT tracking device monitors and adjusts the output voltage and current of the solar cell in real time to find and maintain the maximum power point. Its working principle is usually based on control strategies such as perturbation algorithm or admittance increment method, which continuously adjusts the working point of the solar cell to keep it close to the maximum power output state. During the MPPT tracking process, the test system can collect and record the output voltage, current, power and other parameters of the solar cell in real time. By analyzing these data, the performance of the perovskite battery module under different lighting conditions can be evaluated, including key indicators such as maximum power point and photoelectric conversion efficiency.

[0032] S3, using an IV test system, according to the maximum power point tracking result, further perform IV test scanning on the perovskite battery assembly to be tested with good stability. Preferably, an LED test lamp group or a xenon lamp can be used.

[0033] In this step, according to the maximum power point tracking results, an IV test source meter in the IV test system is used to perform an IV test scan on the perovskite battery components to be tested with good stability; the perovskite battery components to be tested are further classified according to the scanning results.

[0034] In this embodiment, the components after completing the above test flow into the next process step, and the test sequence and time can also be adjusted through the test software system to meet the production line production requirements for perovskite battery power testing. In this embodiment, an IV test system is used, combined with the maximum power point tracking results, to perform IV test scans on the components to be tested with good stability, and the current-voltage IV characteristic curve of the components can be accurately obtained, and then the components can be accurately graded. This helps to improve the quality control level on the production line and ensure the consistency and reliability of the product. In the test method, it is preferred to use an LED test light group or a xenon lamp as a light source. Both light sources can meet the requirements of solar cell testing for light sources, and each has its own advantages. The LED test light group has the advantages of energy saving, environmental protection, and easy control; while the xenon lamp can provide more stable and continuous illumination, which is suitable for long-term testing. The flexibility of this light source enables the test method to be applicable to different test requirements and environmental conditions. Through the test software system, users can easily adjust the test sequence and time to meet the specific requirements of the production line production for perovskite battery power testing. This flexibility enables the test method to better adapt to different production beats and test requirements, and improves the overall efficiency and flexibility of the production line.

[0035] In a feasible embodiment of the present invention, The S2 specifically includes the following steps: a. Turn on the test light group 2, and connect the positive and negative electrodes of the perovskite battery assembly to be tested to the mppt tracking device in turn; b. Calculate the running speed of the slide rail 3 according to the beat of the front-end process and the length of the slide rail 3, as well as the number of cycle measurements of the perovskite battery component to be tested on the slide rail 3, and set the PPT tracking time; c. After the pre-set mppt tracking time is completed, the perovskite battery components to be tested are classified into stability classes, components with poor stability are not allowed to enter the next test, and components with good stability are tested in the next step.

[0036] After the MPPT tracking time is completed, this embodiment classifies the components into stability classes, and can screen out components with stable performance and reliable quality, thereby avoiding unstable components from flowing into subsequent testing or production links, and improving the overall quality of the product. By setting reasonable rail running speed and cycle measurement number, and screening components with poor stability at an early stage, unnecessary testing and waste of resources are avoided, and the utilization rate of test equipment is also improved.
