[0002] This application relates to the field of perovskite testing technology, and more specifically, to a perovskite testing device and a battery production system. Background Technology

[0003] With the popularization and promotion of new energy vehicles, their charging and discharging performance and range have increasingly attracted people's attention and importance. As the power source for new energy vehicles, batteries are widely used.

[0004] Solar cells typically include a perovskite active layer, which is usually formed by annealing a perovskite thin film after most of the solvent has evaporated from a wet perovskite film, allowing for initial crystallization. Most existing perovskite testing devices can only perform one type of spectral measurement. Switching to other devices is required for other types of spectral measurements, resulting in poor applicability and an inability to simultaneously meet diverse spectral testing needs. Summary of the Invention

[0005] In view of this, this application discloses a perovskite testing device and a battery production system.

[0006] A perovskite testing device includes a housing, a stage, a first testing mechanism, and a second testing mechanism. The stage is disposed within the housing and used to hold the sample. The first testing mechanism emits a first test light and acquires the fluorescence spectrum of the first test light passing through the sample. The second testing mechanism emits a second test light and acquires the absorption and scattering spectrum of the second test light passing through the sample. Both the first and second testing mechanisms are detachably mounted within the housing and are spaced apart. This perovskite testing device, with its detachable first and second testing mechanisms, can simultaneously perform fluorescence and absorption / scattering spectral testing on the sample. The same device can integrate at least two different spectral tests, allowing it to meet various spectral testing needs and simplifying the overall structural design while optimizing space utilization.

[0007] In some embodiments, the first testing mechanism includes a first spectrometer, a first optical fiber, and a first transmitter electrically connected together. The first transmitter emits first test light, and the first spectrometer acquires the fluorescence spectrum of the first test light passing through the sample. The first transmitter is detachably housed within a housing, the first spectrometer is located outside the housing, and the first optical fiber passes through the housing and connects the first transmitter and the first spectrometer. This detachable housing of the first transmitter within the housing simplifies the overall design of the testing device and optimizes its space utilization.

[0008] In some embodiments, the first testing mechanism further includes an optical component detachably disposed at the emitting end of the first transmitter and used to adjust the optical path and spot of the first test light. Thus, the optical path and spot of the first test light can be adjusted via the optical component according to actual needs, enhancing the practicality and applicability of the first testing mechanism.

[0009] In some embodiments, the optical components include a first filter, an aperture stop, a second filter, and a condenser lens. The first filter, aperture stop, second filter, and condenser lens are arranged sequentially along the emission path of the first test light. The first filter filters out excess long-wavelength light from the first test light; the aperture stop adjusts the spatial uniformity of the first test light; the second filter filters out excess short-wavelength light from the first test light; and the condenser lens focuses the first test light. This allows for adjustment of the optical path and spot size of the first test light, facilitating successful fluorescence spectroscopy testing of the sample. The structural design is reasonable and simple.

[0010] In some embodiments, the second filter is a semi-transparent mirror, and the second filter is tilted. The first test light is reflected by the second filter and passes through the sample. The first test light passing through the sample is received by the first spectrometer through the first optical fiber. In this way, the first test light, after being reflected by the second filter to the sample, is reflected through the second filter and the condenser lens, and then incident on the first optical fiber and the first spectrometer to obtain the fluorescence spectrum of the first test light passing through the sample. This also facilitates a simplified design of the overall structure of the testing device.

[0011] In some embodiments, the perovskite testing apparatus further includes a first support, which is detachably mounted within the housing and capable of translation and / or lifting. Optical components are detachably mounted on the first support. Thus, when fluorescence spectroscopy testing of the sample is required, the optical components can be mounted on the first support, and the position of the optical components can be changed by translating or lifting the first support, thereby altering the spot size of the first test light, enhancing the practicality and applicability of the first testing mechanism.

[0012] In some embodiments, the perovskite testing apparatus further includes a second support, which is detachably mounted inside the housing and can be flipped. Optical components are detachably mounted on the second support. Thus, when fluorescence spectroscopy testing of the sample is required, the optical components can be mounted on the second support, and by flipping the second support, the angle of the optical components can be changed, thereby altering the illumination angle of the first test light, enhancing the practicality and applicability of the first testing mechanism.

[0013] In some embodiments, the first testing mechanism further includes a halogen lamp connected to a first optical fiber. This allows the first testing mechanism to have a wide spectral testing coverage, enhancing its practicality and applicability.

[0014] In some embodiments, the second testing mechanism includes an electrically connected second spectrometer, a second optical fiber, and a second transmitter. The second transmitter emits a second test light, and the second spectrometer acquires the absorption and scattering spectrum of the second test light passing through the sample. The second transmitter is detachably housed within a housing, the second spectrometer is located outside the housing, and the second optical fiber passes through the housing and connects the second transmitter and the second spectrometer. This detachable housing of the second transmitter within the housing allows the testing device to meet different spectral testing requirements and facilitates a simplified overall structural design, optimizing the space utilization of the testing device.

[0015] In some embodiments, the perovskite testing apparatus further includes a third support, which is detachably mounted inside the housing and can be flipped. The second emitter can be detachably mounted on the third support. Thus, when absorption and scattering spectroscopy testing of the sample is required, the second emitter can be mounted on the third support, and by flipping the third support, the angle of the second emitter can be changed, thereby changing the illumination angle of the second test light, enhancing the practicality and applicability of the second testing mechanism.

[0016] In some embodiments, the perovskite testing apparatus further includes a vacuum flash evaporation chamber, which is detachably disposed within the housing, and the stage is removably disposed within the vacuum flash evaporation chamber. Thus, after the perovskite thin film is formed through vacuum flash evaporation, the sample on the stage does not need to be moved, allowing for subsequent fluorescence spectroscopy and absorption scattering spectroscopy measurements. This makes the operation convenient, time-saving, and improves operational efficiency.

[0017] In some embodiments, the top side of the vacuum flash evaporation chamber is provided with a first window and a second window. The first window is used for the passage of a first test light, and the second window is used for the passage of a second test light. In this way, the first test light can pass through the first window and illuminate the sample inside the vacuum flash evaporation chamber, and the second test light can pass through the second window and illuminate the sample inside the vacuum flash evaporation chamber, thus avoiding the penetration of light into the vacuum flash evaporation chamber.

[0018] In some embodiments, the perovskite testing apparatus further includes a spin coater, which is detachably housed within the enclosure, and a stage is removably mounted on the spin coater. This allows for efficient application of the perovskite solution using a spin coater, significantly improving operational efficiency.

[0019] A battery production system includes the aforementioned perovskite testing device. In this battery production system, both the first and second testing mechanisms are detachably mounted within the housing, enabling simultaneous fluorescence spectroscopy and absorption scattering spectroscopy testing of samples. The same testing device can integrate at least two different spectral tests, allowing it to meet various spectral testing requirements and simplifying the overall structural design of the testing device, thus optimizing its space utilization.

[0032] With the popularization and promotion of new energy vehicles, their charging and discharging performance and range have increasingly attracted people's attention and importance. As the power source for new energy vehicles, batteries are widely used.

[0033] Solar cells typically include a perovskite active layer, which is usually formed by annealing a perovskite thin film after most of the solvent has evaporated from a wet perovskite film, allowing for initial crystallization. Most existing perovskite testing devices can only perform one type of spectral measurement.

The same testing device can integrate at least two different spectral tests, so that the testing device can meet different spectral testing needs, and facilitate the simplification of the overall structure design of the testing device and optimize the space utilization of the testing device.

[0035] Please refer to Figure 1. In one embodiment, the perovskite testing device includes a housing 100, a stage 200, a first testing mechanism 300, and a second testing mechanism 400. The stage 200 is disposed inside the housing 100 and is used to place the sample. The first testing mechanism 300 is used to emit a first testing light and acquire the fluorescence spectrum of the first testing light passing through the sample. The second testing mechanism 400 is used to emit a second testing light and acquire the absorption and scattering spectrum of the second testing light passing through the sample. The first testing mechanism 300 and the second testing mechanism 400 are detachably installed in the housing 100 and are spaced apart from each other.

[0036] It should be noted that the first testing mechanism 300 is capable of emitting a first testing light and, after illuminating the sample with the first testing light, obtaining the fluorescence spectrum of the first testing light passing through the sample; the second testing mechanism 400 is capable of emitting a second testing light and, after illuminating the sample with the second testing light, obtaining the absorption and scattering spectrum of the second testing light passing through the sample.

[0037] In the embodiments of this application, the housing 100 is a component with accommodating space for placing components such as the platform 200, the first testing mechanism 300, and the second testing mechanism 400. The housing 100 can have various structural forms, such as a cuboid, a cylinder, or other shapes. The specific structural form of the housing 100 is not limited here.

[0038] In the embodiments of this application, the stage 200 is a component for placing samples. The stage 200 can have various structural forms, such as a plate-like structure or a block-like structure, and the outer contour of the stage 200 can be circular, square, or other shapes.

[0039] In the embodiments of this application, the first testing mechanism 300 is a component used to perform fluorescence spectroscopy testing on the sample. The first testing mechanism 300 can have various structural forms; for example, the first testing mechanism 300 includes a fluorescence spectrometer, which is used to perform fluorescence spectroscopy testing on the sample.

[0040] In the embodiments of this application, the second testing mechanism 400 is a component used to perform absorption and scattering spectroscopy testing on the sample. The second testing mechanism 400 can have various structural forms; for example, the second testing mechanism 400 includes an absorption and scattering spectrometer, which is used to perform absorption and scattering spectroscopy testing on the sample.

[0041] The perovskite testing device described above has a first testing mechanism 300 and a second testing mechanism 400 that can be detachably installed in the housing 100. It can simultaneously perform fluorescence spectroscopy and absorption scattering spectroscopy tests on the sample. The same testing device can integrate at least two different spectral tests, so that the testing device can meet different spectral testing requirements and facilitate the simplification of the overall structure design of the testing device and optimize the space utilization of the testing device.

[0042] According to some embodiments of this application, please refer to FIG1. ​​The first testing mechanism 300 includes a first spectrometer 310, a first optical fiber 320 and a first transmitter 330 electrically connected. The first transmitter 330 is used to emit a first test light, and the first spectrometer 310 is used to acquire the fluorescence spectrum of the first test light passing through the sample. The first transmitter 330 is detachably disposed inside the housing 100, the first spectrometer 310 is disposed outside the housing 100, and the first optical fiber 320 passes through the housing 100 and connects the first transmitter 330 and the first spectrometer 310.

[0043] It is understood that the first transmitter 330 is used to emit the first test light, and after the first test light illuminates the sample, it is incident on the first optical fiber 320 and the first spectrometer 310 to obtain the fluorescence spectrum of the first test light passing through the sample.

[0044] In the embodiments of this application, the housing 100 is provided with a first clearance hole, the first transmitter 330 is located inside the housing 100, the first spectrometer 310 is located outside the housing 100, one end of the first optical fiber 320 is located inside the housing 100, and the other end of the first optical fiber 320 passes through the first clearance hole and is connected to the first spectrometer 310. The first clearance hole can be a round hole, a square hole, or a hole of other shapes.

[0045] In the embodiments of this application, the first spectrometer 310 is a fluorescence spectrometer, which analyzes the composition and properties of the sample by measuring the fluorescence intensity and wavelength distribution emitted by the sample.

[0046] With the above configuration, the first transmitter 330 is detachably housed inside the housing 100, enabling the testing device to meet different spectral testing requirements and simplifying the overall structural design of the testing device, thereby optimizing the space utilization of the testing device.

[0047] According to some embodiments of this application, please refer to FIG1. ​​The first testing mechanism 300 further includes an optical component 500, which is detachably disposed at the emission end of the first transmitter 330 and is used to adjust the optical path and spot of the first test light.

[0048] It should be noted that the optical component 500 is located at the emitting end of the first transmitter 330. The first test light emitted by the first transmitter 330 is incident on the optical component 500, reflected by the optical component 500 to the sample, and then incident on the first optical fiber 320 and the first spectrometer 310 to obtain the fluorescence spectrum of the first test light passing through the sample.

[0049] In the embodiments of this application, the optical component 500 is a component used to adjust the optical path and light spot of the first test light. The optical component 500 can be a combination of various types of lenses to meet different optical path and light spot requirements. For example, the optical component 500 includes lenses such as semi-transparent lenses and focusing lenses to adjust the optical path and light spot size.

[0050] In the embodiments of this application, the optical component 500 is detachably disposed at the emission end of the first transmitter 330. The optical component 500 and the first transmitter 330 can be detachably connected in a variety of ways, such as screwing, snapping or plugging the optical component 500 and the emission end of the first transmitter 330.

[0051] In the embodiments of this application, the number of optical components 500 is not limited to one, that is, the number of optical components 500 can be at least two. When the number of optical components 500 is at least two, each optical component 500 can be arranged side by side in the same direction or in other arrangements.

[0052] With the above settings, the optical path and spot of the first test light can be adjusted by the optical component 500 according to actual needs, thereby enhancing the practicality and applicability of the first test mechanism 300.

[0053] According to some embodiments of this application, please refer to FIG1. ​​The optical component 500 includes a first filter 510, an aperture 520, a second filter 530, and a condenser lens 540. The first filter 510, aperture 520, second filter 530, and condenser lens 540 are arranged sequentially according to the emission path of the first test light. The first filter 510 is used to filter out excess long-wavelength light in the first test light. The aperture 520 is used to adjust the spatial uniformity of the first test light. The second filter 530 is used to filter out excess short-wavelength light in the first test light. The condenser lens 540 is used to focus the first test light.

[0054] Understandably, the first test light emitted by the first transmitter 330 is sequentially incident on the first filter 510 and the aperture 520, then reflected by the second filter 530 to the sample, and after being reflected through the second filter 530 and the condenser lens 540, it is incident on the first optical fiber 320 and the first spectrometer 310 to obtain the fluorescence spectrum of the first test light passing through the sample.

[0055] In the embodiments of this application, the first filter 510 is a component used to filter out excess long-wavelength light in the first test light. In some embodiments, the first filter 510 is a long-pass filter, the main material of which is optical glass or optical plastic. The surface of the long-pass filter is coated with a special interference film. These interference films produce different phase differences for light of different wavelengths. Light waves within a specific wavelength range interfere with each other in the film layer, reinforcing each other, and thus pass smoothly through the filter; while light waves of other wavelengths interfere with each other in the film layer, canceling each other out and being blocked by the filter. Depending on its materials and manufacturing process, long-pass filters can also be divided into various types, such as glass-based long-pass filters, plastic-based long-pass filters, hard-film long-pass filters, and soft-film long-pass filters.

[0056] In the embodiments of this application, the aperture 520 is a component used to adjust the spatial uniformity of the first test light. By properly setting the aperture 520, the amount and direction of light entering the optical system can be controlled, thereby improving the imaging quality. There are many types of apertures 520, the most common being field apertures 520, aperture diaphragms 520, vignetting apertures 520, and stray light removal apertures 520.

[0057] In embodiments of this application, the second filter 530 is a component used to filter out excess short-wavelength light in the first test light. In some embodiments, the second filter 530 is a short-pass filter, whose main material is optical glass or optical plastic, and is mainly used to block the passage of interfering wavelength light above a certain specific wavelength band, while allowing light below that specific wavelength band to pass through.

[0058] In the embodiments of this application, the condenser lens 540 is a component used to focus the first test light. When the light passes through the condenser lens 540, the light will be refracted because the refractive index of the lens material is different from that of the surrounding environment, so that the originally dispersed light can be concentrated.

[0059] With the above settings, the optical path and spot of the first test light can be adjusted, and the fluorescence spectrum test of the sample can be carried out smoothly. The structural design is reasonable and simple.

[0060] According to some embodiments of this application, please refer to FIG1, the second filter 530 is a semi-transparent lens and the second filter 530 is tilted; the first test light is reflected by the second filter 530 and passes through the sample, and the first test light passing through the sample is received by the first spectrometer 310 through the first optical fiber 320.

[0061] In the embodiments of this application, the second filter 530 is tilted, and the tilt angle of the second filter 530 is such that the first test light is reflected by the second filter 530 and passes through the sample. In some embodiments, the tilt angle of the second filter 530 can be a specific value such as 30 degrees, 60 degrees or 90 degrees.

[0062] In the embodiments of this application, the second filter 530 is a semi-transparent lens. A semi-transparent lens is a filter that can divide the intensity of an incident light beam into two parts, one part of which is transmitted and the other part is reflected. The intensity of transmission and reflection of the semi-transparent lens can be made as needed, such as 50% transmission and 50% reflection, 60% transmission and 40% reflection, 70% transmission and 30% reflection, etc.

[0063] With the above settings, the first test light can be reflected to the sample through the second filter 530, and then reflected through the second filter 530 and the condenser lens 540 before being incident on the first optical fiber 320 and the first spectrometer 310 to obtain the fluorescence spectrum of the first test light passing through the sample. This also facilitates the simplification of the overall structure design of the testing device.

[0064] According to some embodiments of this application, please refer to FIG1. ​​The perovskite testing device further includes a first support 610, which is detachably disposed within the housing 100 and is capable of translation and / or lifting. The optical component 500 is detachably disposed on the first support 610.

[0065] It should be noted that when fluorescence spectroscopy testing of the sample is required, the optical component 500 can be placed on the first support 610, and the position of the optical component 500 can be changed by translating or raising the first support 610, thereby changing the spot size of the first test light; when fluorescence spectroscopy testing of the sample is not required, the optical component 500 can be removed from the first support 610.

[0066] In the embodiments of this application, the optical component 500 can be detachably mounted on the first bracket 610. The optical component 500 and the first bracket 610 can be detachably connected in a variety of ways, such as screwing, snapping, or plugging the optical component 500 and the first bracket 610.

[0067] In the embodiments of this application, the first bracket 610 is detachably disposed within the housing 100 and is capable of translation and / or lifting. The first bracket 610 can be detachably disposed within the housing 100 in various ways, such as screwing, snapping, or inserting the first bracket 610 into the housing 100. The first bracket 610 is capable of translation in the horizontal direction and / or lifting in the vertical direction.

[0068] With the above settings, when fluorescence spectroscopy testing of samples is required, the optical component 500 can be placed on the first support 610, and the position of the optical component 500 can be changed by translating or raising the first support 610, thereby changing the spot size of the first test light, which enhances the practicality and applicability of the first testing mechanism 300.

[0069] According to some embodiments of this application, please refer to FIG1. ​​The perovskite testing device further includes a second support 620, which is detachably disposed within the housing 100 and can be flipped. The optical component 500 can be detachably disposed on the second support 620.

[0070] It should be noted that when fluorescence spectroscopy testing of the sample is required, the optical component 500 can be placed on the second support 620, and the angle of the optical component 500 can be changed by flipping the second support 620, thereby changing the illumination angle of the first test light; when fluorescence spectroscopy testing of the sample is not required, the optical component 500 can be removed from the second support 620.

[0071] In the embodiments of this application, the optical component 500 can be detachably mounted on the second bracket 620. The optical component 500 and the second bracket 620 can be detachably connected in a variety of ways, such as screwing, snapping, or plugging the optical component 500 and the second bracket 620.

[0072] In the embodiments of this application, the second bracket 620 is detachably disposed within the housing 100 and is capable of translation and / or lifting. The second bracket 620 can be detachably disposed within the housing 100 in various ways, such as screwing, snapping, or inserting the second bracket 620 into the housing 100. The second bracket 620 can be flipped in the horizontal direction and / or in the vertical direction.

[0073] With the above settings, when fluorescence spectroscopy testing of samples is required, the optical component 500 can be placed on the second support 620, and the angle of the optical component 500 can be changed by flipping the second support 620, thereby changing the illumination angle of the first test light, which enhances the practicality and applicability of the first testing mechanism 300.

[0074] According to some embodiments of this application, referring to FIG1, the first testing mechanism 300 further includes a halogen lamp 700, which is connected to the first optical fiber 320.

[0075] In the embodiments of this application, the halogen lamp 700 is used for absorption and scattering spectroscopy testing. As one of the light sources for spectral measurement, the halogen lamp 700 has high brightness and a wide spectral coverage, which can meet the needs of some measurement occasions that require high brightness, such as very bright environments or spectral measurements with a large scanning range.

[0076] The above settings enable the first testing unit 300 to have a wide spectral testing coverage, thereby enhancing its practicality and applicability.

[0077] According to some embodiments of this application, referring to FIG1, the second testing mechanism 400 includes a second spectrometer 410, a second optical fiber 420 and a second transmitter 430 electrically connected. The second transmitter 430 is used to emit a second test light, and the second spectrometer 410 is used to acquire the absorption and scattering spectrum of the second test light passing through the sample.
