Description

Technical Field

[0001] This invention relates to the field of organic compound solar cell technology, and in particular to a pre-illumination synergistic aging test system and method for large-size perovskite modules. Background Technology

[0002] In the industrialization of perovskite solar cells, reliability testing of large-size modules (greater than 200×200mm) faces three major technical challenges: First, due to the significant increase in ion migration path as the module size increases, the current density at the edge of a 300×300mm module decreases by more than 30% compared to the center. Traditional small-area IV testers struggle to capture this spatial non-uniform decay, resulting in a lifetime prediction deviation of more than 20%. Second, existing light decay chambers, such as xenon lamp aging chambers, only provide uniform irradiation across the entire spectrum, failing to achieve the synergistic effect of dual-band precise control required for pre-passivation—450nm blue light excitation of iodine vacancy migration and 800nm ​​infrared light reduction of ion migration activation energy—leading to excessive initial efficiency loss in the module. Furthermore, the separation of pre-illumination defect repair and accelerated aging stress, requiring the module to be transferred to aging equipment after pre-illumination, causes passivation interface relaxation and efficiency hysteresis exceeding 8%, ultimately resulting in test results that fail to accurately reflect the decay dynamics of the module under service conditions. The aforementioned challenges severely restrict the mass production quality assessment and failure mechanism analysis of large-size components, and there is an urgent need to develop a collaborative testing scheme that integrates multispectral modulation and in-situ monitoring.

[0003] Existing technology 1, publication number CN109449300A, discloses an online monitoring device and method for perovskite solar cell production, including a color analysis device and / or a temperature testing device, as well as a data processing feedback system. The color analysis device includes a color probe, and the temperature testing device includes a temperature probe. The perovskite solar cell substrate is placed in a vacuum-sealed chamber for vapor deposition. An evaporation source controlled by an evaporation control system is installed inside the chamber. The color probe and temperature probe are respectively aimed at the surface or back surface of the perovskite solar cell substrate. The analysis data from the data processing feedback system is fed back to the evaporation control system. Although monitoring various performance parameters during the perovskite thin film production process controls the reaction process and improves the repeatability of perovskite thin film production in batches, this method only focuses on real-time monitoring of the perovskite thin film production process (color / temperature parameters) and lacks analysis of the aging behavior of the formed components under combined stress conditions, especially failing to simulate outdoor degradation scenarios involving multiple factors coupled with light, heat, and humidity.

[0004] Prior art two, publication number CN111509129A, discloses a method for preparing highly crystalline perovskite and its product application, including the following steps: preparing a main group metal halide salt solution and a halide organic salt solution; preparing a mixture of halide organic salt and organic cation; preparing a mixture of metal halide salt, inhibitor, and additive; mixing the mixture of halide organic salt and organic cation with the mixture of metal halide salt, inhibitor, and additive uniformly, and then allowing it to stand for aging to obtain a two-dimensional / quasi-two-dimensional layered perovskite solution; preparing the two-dimensional / quasi-two-dimensional layered perovskite solution on a substrate by coating, and then annealing to obtain perovskite. Although the crystallization rate is regulated by intervening in the crystallization inhibitor, improving the matching degree between the A-site ion transport and assembly rate and the perovskite crystallization rate, thereby reducing the disorder of the crystal structure and improving the crystallinity of the perovskite, the problem of performance gradient decay caused by uneven illumination in actual use of the component is not solved.

[0005] Prior art three, publication number CN112018245A, discloses an anatase titanium dioxide mesocrystalline electron transport layer, its low-temperature preparation method, and its application in perovskite solar cells. Specifically, it relates to an anatase titanium dioxide mesocrystalline electron transport layer, its low-temperature preparation method, and its application in perovskite solar cells. First, a dense titanium dioxide thin film is prepared on clean FTO using a chemical bath deposition method. Next, anatase titanium dioxide mesocrystalline material is dispersed in anhydrous ethanol, ultrasonicated, and then spin-coated onto the surface of the dense titanium dioxide thin film. Heating is then performed to obtain an electron transport layer. Finally, a perovskite layer and a hole transport layer are prepared on the electron transport layer and gold is deposited. A cell is then assembled for testing its photoelectric performance. Although the preparation process is simple and the resulting large-area device exhibits good photoelectric performance, showing promising commercial application prospects, it does not address long-term reliability assessment of the component, resulting in a need for further improvement in spatial resolution performance monitoring during aging tests.

[0006] Current technologies 1, 2, and 3 cannot achieve uniform aging control and spatially resolved performance degradation characterization of large-size perovskite modules under multi-stress coupling conditions (light-heat-humidity). Therefore, this invention provides a pre-illumination co-aging testing system and method for large-size perovskite modules. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a pre-illumination synergistic aging test system for large-size perovskite modules, comprising:

[0008] The optical attenuation subsystem is used to integrate a programmable dual-band light source array, which separates the light source into blue light in the reflection path and near-infrared light in the transmission path through a beam splitter and a bandpass filter; it provides dual-band coordinated irradiation of the perovskite component in the pre-illumination stage and switches to full-spectrum mode in the aging stage.

[0009] The current-voltage testing subsystem is used to scan the local current-voltage curves of the perovskite module using a multi-channel probe card combined with an integrated programmable dual-band light source array, and to calculate the carrier lifetime of each region; and to feed back the variance of the carrier lifetime value to the control subsystem.

[0010] The control subsystem is used to dynamically adjust the LED intensity of the partitioned supplementary lighting array based on the proportional-integral-derivative control algorithm; and to receive the variance of the carrier lifetime from feedback.

[0011] The area supplementary lighting array subsystem is used to divide the surface of the perovskite component into a 9-grid area, with each area equipped with an LED supplementary lighting module to compensate for edge light intensity attenuation; the LED intensity of each area is dynamically adjusted according to the instructions of the control subsystem.

[0012] Optional, optical attenuation subsystem, including:

[0013] The spectral separation and energy matching component is used to start the xenon lamp light source and generate a broadband composite beam. The beam is precisely spectrally clipped by the beam splitter and reflector group to generate a 450nm blue light reflection path and an 800nm ​​near-infrared transmission path with independent physical paths. It outputs two independent beams with wavelength and spatial directionality, and presets an intensity ratio of 1:1.6.

[0014] A dual-band coupled excitation component is used to guide two independent light beams to the surface of the perovskite component, inducing defect-co-excited states inside the perovskite component; the 450nm blue light path selectively enhances the migration activity of iodine vacancies, while the 800nm ​​near-infrared light path simultaneously weakens the activation energy barrier for ion migration; the two effects are coupled in time and space to jointly form a dynamic defect activation and transport network.

[0015] The dynamic repair field forming component is used for defect activation and transport networks, inducing directional rearrangement of ions and vacancies within the perovskite component to form a dynamic defect repair field.

[0016] Optional, current-voltage test subsystem, including:

[0017] The differentiated configuration component is used for the multi-channel probe card to establish electrical contact with the surface of the perovskite module according to the preset nine-point matrix coordinates; a probe layout with a 10 mm pitch is used in the central area and a contact pressure of 20 g is applied, while a probe layout with a 5 mm pitch is used in the edge area and a contact pressure of 30 g is applied. The differentiated configuration forms an electrical contact network with spatial resolution on the surface of the perovskite module.

[0018] The bias scanning component is used to establish an electrical contact network to perform synchronous measurements under dual-band illumination conditions; each probe performs voltage bias scanning on its respective perovskite component region while maintaining constant contact pressure, records the corresponding current response, and obtains nine sets of current-voltage data sequences with spatiotemporal correlation.

[0019] The time parameter conversion component is used to perform time-domain analysis on the obtained current-voltage data sequence, focusing on extracting the voltage decay characteristics of each test point in the open-circuit state; by calculating the time parameter of the second derivative extreme point of the voltage decay curve, it is converted into the corresponding carrier lifetime value, forming a set of carrier lifetime distributions in nine regions on the surface of the perovskite module.

[0020] Optional, a control subsystem includes:

[0021] The variance comparison component is used to receive the variance of the carrier lifetime value, compare the variance with a preset 15% threshold, and generate a performance uniformity error signal at the current moment.

[0022] The collaborative computing component is used to input the performance uniformity error signal into the three-element collaborative computing unit and simultaneously execute three calculation processes: proportionally amplify the current error signal, integrate the historical error accumulation value, and differentiate the error change trend; the three processing results are weighted and fused to generate a composite control signal that includes the intensity adjustment direction and amplitude.

[0023] The signal parsing component is used to parse the composite control signal into nine independent LED driving commands according to the nine-grid area layout, and send them to the 450nm and 800nm ​​LED supplementary lighting modules in the corresponding areas respectively.

[0024] Optional signal analysis components include:

[0025] The matrix establishment sub-component is used to receive composite control signals and simultaneously call the initial performance distribution data obtained by the perovskite component. Based on the initial performance distribution data, a spatial weight allocation matrix is ​​established, in which the weight value of the edge region is set to 1.5 and the weight value of the center region is set to 1.0, forming a regionally differentiated control benchmark.

[0026] The adjustment quantity processing sub-component is used to perform regional weighted operations on the intensity adjustment amplitude in the composite control signal and the weight values ​​corresponding to the nine regions, that is, to multiply the global intensity adjustment amplitude by the weight values ​​of each region to generate nine differentiated light intensity adjustment quantities with spatial characteristics.

[0027] The current output sub-component is used to calculate the driving current value of the 450nm LED module and the driving current value of the 800nm ​​LED module in each region according to the preset intensity ratio of 1:1.6, and finally outputs the independent driving instruction set corresponding to each of the nine regions.

[0028] Optional, matrix building subcomponent, includes:

[0029] The distribution and arrangement module is used to call up the carrier lifetime values ​​of nine spatial locations collected during the initial pre-illumination stage, arrange them according to a nine-square grid spatial distribution, and form the initial performance distribution map of the component.

[0030] The ratio calculation module is used to calculate the ratio of the carrier lifetime value of each edge region in the initial performance distribution map of the component to the reference value of the center region. When the lifetime ratio of a certain edge region is lower than the set compensation threshold of 85%, the edge region is marked as a region with high compensation requirement.

[0031] The identification result module is used to assign corresponding weight coefficients to each position in the nine-square grid matrix based on the identification results of the high compensation demand area. The central area is assigned a base weight value of 1.0, and the high compensation demand area is assigned an enhanced weight value of 1.5, generating a weight allocation matrix with spatial differentiation characteristics.

[0032] Optional, distributed arrangement module, including:

[0033] The coordinate mapping submodule is used to receive carrier lifetime values ​​at nine spatial locations; at the same time, it calls the predefined nine-grid spatial coordinate mapping relationship, which is established based on the physical size of the component surface of 300×300 mm, dividing the perovskite component surface into nine 100×100 mm square regions.

[0034] The grid storage submodule is used to inject the nine carrier lifetime values ​​into the corresponding grid cells in the nine-grid spatial coordinate mapping relationship according to their corresponding physical measurement positions; each grid cell stores a carrier lifetime value corresponding to its spatial position, thus constructing a performance data matrix containing spatial position information;

[0035] The continuous constraint submodule is used to apply spatial continuity constraints to the filled nine-grid performance data matrix. By verifying the gradation characteristics of adjacent grid cell data, it confirms that the data arrangement conforms to the performance distribution law of the component surface and forms an initial performance distribution map of the component with a clear spatial index relationship.

[0036] Optional, coordinate mapping submodule, includes:

[0037] The boundary range confirmation unit is used to read the physical size parameters of the perovskite module, establish a plane rectangular coordinate system with the lower left corner of the perovskite module as the origin, and obtain the boundary range data of 300×300 mm on the surface of the perovskite module.

[0038] The equal division calculation unit is used to perform equal division calculation based on the boundary range data. It inserts two equally spaced dividing points along the X-axis and Y-axis directions respectively, dividing the surface of the perovskite component into nine regions in three rows and three columns, generating a set of boundary coordinates for nine 100×100 mm square regions.

[0039] The identifier allocation unit is used to assign a unique spatial identifier to each square region based on the set of region boundary coordinates, generate a nine-grid spatial coordinate mapping relationship in the order from left to right and from bottom to top, and establish the correspondence between the physical location of each region and its internal addressing address.

[0040] Optional, equally divided calculation unit, comprising:

[0041] The equal division calculation unit reads the total length of the X-axis (300 mm) and the total length of the Y-axis (300 mm) from the boundary range data, divides each axial length by 3, and obtains the trisection spacing value of 100 mm.

[0042] The dividing point locator calculates and records two position coordinates of 100 mm and 200 mm in the X-axis direction and two position coordinates of 100 mm and 200 mm in the Y-axis direction based on the three equal interval values, forming four dividing point coordinate data;

[0043] The region boundary generator combines the coordinates of the four segmentation points with the component boundary coordinates, and forms grid lines by connecting the various segmentation points. Finally, it outputs a set of boundary coordinates for nine square regions, each region corresponding to a 100×100 mm detection unit.

[0044] The pre-illumination synergistic aging test method for large-size perovskite modules provided by this invention includes the following steps:

[0045] The optical decay subsystem processes the changes in the physicochemical state of the perovskite module through dual-band synergistic irradiation; the changes in the physicochemical state of the module are then used by the current-voltage testing subsystem to generate quantitative data, including the carrier lifetime of each region.

[0046] The current-voltage testing subsystem calculates the variance of the carrier lifetime to obtain the performance uniformity evaluation result of the perovskite module; the performance uniformity evaluation result is used by the control subsystem to form a PID algorithm output signal;

[0047] The control subsystem processes the PID algorithm output signal to obtain the LED intensity adjustment signal for each supplementary lighting area; the LED intensity adjustment signal forms a uniform lighting environment through the supplementary lighting array subsystem, resulting in the compensated light field on the surface of the perovskite component.

[0048] This invention achieves precise aging characterization and dynamic compensation control under multidimensional stress coupling. In the pre-illumination stage, dual-band synergistic irradiation is used: 450nm blue light excites iodine vacancy migration, and 800nm ​​near-infrared light promotes ion redistribution, specifically inducing the intrinsic defect behavior of perovskite materials. During the aging stage, the system switches to full-spectrum AM1.5G and superimposes temperature and humidity stress to fully simulate actual outdoor degradation conditions. The current-voltage testing subsystem captures local performance parameters, such as carrier lifetime distribution, in real time using a multi-channel probe or a 9-point electrode matrix, providing quantitative feedback to the control subsystem. When the carrier lifetime variance exceeds a 15% threshold, a dynamic compensation mechanism is triggered—the partitioned supplementary lighting array adjusts the LED intensity in each region based on a PID algorithm to compensate for non-uniform aging caused by edge light intensity decay.

[0064] Example 1: As Figure 1 As shown, this embodiment of the invention provides a pre-illumination synergistic aging test system for large-size perovskite modules, comprising:

[0065] The optical attenuation subsystem is used to integrate a programmable dual-band light source array. It separates the light source into a 450nm blue light reflection path and an 800nm ​​near-infrared light transmission path through a beam splitter and a bandpass filter. In the pre-illumination stage, it provides dual-band synergistic irradiation of the perovskite component. The blue light excites iodine vacancy migration, and the infrared light promotes ion redistribution. In the aging stage, it switches to a full-spectrum mode, AM 1.5G, 1.2 Sun, while maintaining aging stress conditions of 85℃ / 85%RH.

[0066] The current-voltage testing subsystem is used to scan the local current-voltage curves or 9-point matrix of the perovskite component using a multi-channel probe card or 9-point contact electrode, combined with an integrated programmable dual-band light source array, and calculate the carrier lifetime of each region; during the pre-illumination and aging stages, it collects data and feeds back the variance of the carrier lifetime value to the control subsystem.

[0067] The control subsystem is used to dynamically adjust the LED intensity of the partitioned supplementary lighting array based on the proportional-integral-derivative control algorithm; it receives the variance of the carrier lifetime from feedback; if the variance is >15%, it calculates the control output.

[0068] The area supplementary lighting array subsystem is used to divide the surface of the perovskite component into a 9-grid area, with each area equipped with 450nm and 800nm ​​LED supplementary lighting modules to compensate for edge light intensity attenuation; according to the instructions of the control subsystem, the LED intensity of each area is dynamically adjusted.

[0069] The working principle and beneficial effects of the above technical solution are as follows: The optical attenuation subsystem of this embodiment is used to integrate a programmable dual-band light source array. It separates the light source into a 450nm blue light reflection path and an 800nm ​​near-infrared light transmission path using a beam splitter and bandpass filter. During the pre-illumination stage, it provides dual-band synergistic irradiation of the perovskite component. Blue light excites iodine vacancy migration, and infrared light promotes ion redistribution. During the aging stage, it switches to a full-spectrum mode (AM 1.5G, 1.2 Sun) while maintaining aging stress conditions of 85℃ / 85%RH. The current-voltage testing subsystem is used to employ a multi-channel probe card or... Nine contact electrodes, combined with an integrated programmable dual-band light source array, scan the local current-voltage curves or a nine-point matrix of the perovskite module and calculate the carrier lifetime of each region. During the pre-illumination and aging stages, data is collected, and the variance of the carrier lifetime value is fed back to the control subsystem. The control subsystem dynamically adjusts the LED intensity of the zoned supplementary lighting array based on a proportional-integral-derivative control algorithm. It receives the feedback variance of the carrier lifetime; if the variance > 15%, the control output is calculated. The zoned supplementary lighting array subsystem divides the surface of the perovskite module into a nine-grid area, each area equipped with 450nm and 800nm ​​LED supplementary lighting modules to compensate for edge light intensity attenuation. According to the instructions of the control subsystem, the LED intensity of each area is dynamically adjusted (the specific principle is as follows). Figure 2(As shown). The above scheme achieves accurate aging characterization and dynamic compensation control under multi-dimensional stress coupling. In the pre-illumination stage, dual-band synergistic irradiation is used: 450nm blue light excites iodine vacancy migration, and 800nm ​​near-infrared light promotes ion redistribution, specifically inducing the intrinsic defect behavior of perovskite materials. In the aging stage, the system switches to full-spectrum AM1.5G (1.2Sun) and superimposes temperature and humidity stress (85℃ / 85%RH) to fully simulate actual outdoor attenuation conditions. The current-voltage testing subsystem captures local performance parameters, such as carrier lifetime distribution, in real time through multi-channel probes or a 9-point electrode matrix, providing quantitative feedback to the control subsystem. When the carrier lifetime variance exceeds the 15% threshold, a dynamic compensation mechanism is triggered—the partitioned supplementary lighting array adjusts the LED intensity of each region (450nm / 800nm ​​dual-band) based on a PID algorithm to compensate for the non-uniform aging caused by edge light intensity attenuation.

[0070] In summary, this embodiment achieves programmable control of material defect excitation, spatially resolved monitoring of performance degradation during aging, and active compensation for non-uniform stress based on real-time feedback, providing a multi-parameter coupled accelerated aging platform for perovskite module reliability research. This embodiment is the first to apply pre-illumination technology to a 300×300mm module, resolving edge effects; and avoids additional light source costs through optical path multiplexing.

[0071] Example 2: Figure 3 As shown, based on Embodiment 1, the optical attenuation subsystem provided in this embodiment of the invention includes:

[0072] The spectral separation and energy matching component is used to start the xenon lamp light source and generate a broadband composite beam. The beam is precisely spectrally clipped by the beam splitter and reflector group to generate a 450nm blue light reflection path and an 800nm ​​near-infrared transmission path with independent physical paths. It outputs two independent beams with specific wavelengths and spatial directivity, and presets an intensity ratio of 1:1.6.

[0073] A dual-band coupled excitation component is used to guide two independent light beams to the surface of the perovskite component, inducing defect-co-excited states inside the perovskite component; the 450nm blue light path selectively enhances the migration activity of iodine vacancies, while the 800nm ​​near-infrared light path simultaneously weakens the activation energy barrier for ion migration; the two effects are coupled in time and space to jointly form a dynamic defect activation and transport network.

[0074] The dynamic repair field forming component is used for defect activation and transport networks, inducing directional rearrangement of ions and vacancies within the perovskite component to form a dynamic defect repair field.

[0075] The working principle and beneficial effects of the above technical solution are as follows: The spectral separation and energy matching component of this embodiment is used to start the xenon lamp light source, generating a broadband composite beam that is precisely spectrally clipped by the beam splitter and reflector group to generate a 450nm blue light reflection path and an 800nm ​​near-infrared transmission path with independent physical paths; two independent beams with specific wavelengths and spatial directivity are output, and a preset intensity ratio of 1:1.6 is used; the dual-band coupling excitation component is used to guide the two independent beams to the surface of the perovskite component, inducing defect co-excitation state inside the perovskite component; the 450nm blue light path selectively enhances the migration activity of iodine vacancies, while the 800nm ​​near-infrared light path simultaneously weakens the activation energy barrier of ion migration; the two effects are coupled in time and space to jointly constitute a dynamic defect activation and transport network; the dynamic repair field forming component is used for defect activation and transport network, inducing directional rearrangement of ions and vacancies inside the perovskite component to form a dynamic defect repair field. The above scheme establishes a dual-wavelength physically isolated optical path system through precise tailoring of the xenon lamp broadband light source. Spectral separation design achieves two key control dimensions: spatially ensuring independent transmission of the two beams without interference, and energy-wise pre-setting an intensity ratio of 1:1.6 to provide precise optical input conditions for the excitation process. The dual-band coupling mechanism establishes spatiotemporally coordinated defect regulation within the perovskite: the blue light component specifically enhances the iodine vacancy migration activity, while the near-infrared component systematically reduces the ion migration barrier. This dual-path synergy overcomes the limitations of single-wavelength regulation, forming a dynamic defect activation-transport coupling network. Based on the ion / vacancy directional migration channels established by the preceding process, the system spontaneously forms a dynamic repair field within the material. The light-induced lattice defect rearrangement process maintains the dynamic balance of the repair field through continuous light-matter interaction, achieving self-stabilization of the material's microstructure.

[0076] In summary, this embodiment constructs a complete photo-induced defect control chain through a three-level cascade mechanism of spectral separation, dual-band coupling, and dynamic field formation. Without external intervention, it achieves in-situ control and self-repair of defect states in perovskite materials solely through preset optical parameters, providing a closed-loop solution for the stability control of photosensitive materials. In this embodiment, the xenon lamp source is separated into a 450nm reflective light path and an 800nm ​​transmittance light path; a beam splitter and bandpass filter assembly are added, with the xenon lamp source power ≥ 5kW; dual-band (450nm + 800nm) irradiation is used in the pre-illumination stage, with an intensity ratio of 1:1.6; during the aging stage, 9-point IV curves are scanned every 2 hours to generate a current density decay thermogram.

[0077] Example 3: Based on Example 2, the spectral separation and energy matching component of this invention includes:

[0078] An activated substrate is used to construct a sub-component. Optical-grade quartz glass is selected as the base substrate, and the base substrate is placed in a nitrogen plasma treatment environment. By controlling the plasma power density and treatment time, dangling bond sites are oriented to form a nitrided surface layer on the surface of the base substrate, thus obtaining an activated substrate with specific surface energy and chemical properties.

[0079] Asymmetric reflector components were deposited using an activated substrate as the base, and high-refractive-index and low-refractive-index layers were alternately deposited sequentially by reactive magnetron sputtering. The alternating deposition was performed in a high-low-high-low sequence, for a total of 15 cycles. Utilizing the multilayer interference effect, an asymmetric reflectivity distribution was constructed at the interface: for broadband composite light incident perpendicular to the interface, photons in the 450nm band were strongly reflected due to coherent constructive interference, forming a 450nm blue light reflection path; photons with wavelengths greater than 500nm were mostly transmitted due to destructive interference, serving as a broadband residual beam.

[0080] The high refractive index layer is composed of titanium oxide, with a thickness controlled at 56.25 nm, corresponding to one-quarter of the optical thickness of 450 nm wavelength light propagating in this material; the low refractive index layer is composed of silicon dioxide, with a thickness strictly controlled at 76.92 nm, also one-quarter of the optical thickness of 450 nm wavelength light in this material.

[0081] The compensation layer integrated sub-component is used to deposit an aluminum oxide thin film through a sputtering process as a phase compensation layer. Based on wave optics theory, it fine-tunes the wavefront phase of the near-infrared light transmitted through the interface. By controlling the physical thickness of the compensation layer to 172nm, it introduces an additional phase difference of π / 4 radians into the 800nm ​​light. This compensates for the phase distortion of the 800nm ​​transmitted light path caused by multilayer film reflection, and provides the optical field conditions for constructing a dynamic defect activation and transport network.

[0082] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, the activated substrate construction sub-assembly uses optical-grade quartz glass as the base substrate, placing it in a nitrogen plasma treatment environment. By controlling the plasma power density and treatment time, dangling bond sites are directionally generated on the surface of the base substrate, forming a nitrided surface layer. An activated substrate with specific surface energy and chemical properties is obtained. The asymmetric reflection deposition sub-assembly uses the activated substrate as a base, employing reactive magnetron sputtering to alternately deposit high-refractive-index layers and low-refractive-index layers. Alternating deposition is performed in a high-low-high-low sequence, constructing 15 cycles. Utilizing the multilayer film interference effect, an asymmetric reflectivity distribution is constructed at the interface: for broadband reflections incident perpendicular to the interface... The combined light source consists of a 450nm blue light reflection path formed by strong reflection of photons in the 450nm band due to coherent constructive interference. Photons with wavelengths greater than 500nm are mostly transmitted due to destructive interference, serving as a broadband residual beam. The high-refractive-index layer is composed of titanium oxide with a thickness controlled at 56.25nm, corresponding to one-quarter of the optical thickness of 450nm wavelength light propagating in this material. The low-refractive-index layer is composed of silicon dioxide with a thickness controlled at 76.92nm, also one-quarter of the optical thickness of 450nm wavelength light in this material. The compensation layer integrated sub-assembly is used to deposit an aluminum oxide thin film through sputtering as a phase compensation layer, which finely adjusts the wavefront phase of the near-infrared light transmitted through the interface based on wave optics theory. The physical thickness of the layer is controlled at 172 nm, introducing an additional phase difference of π / 4 radians to the 800 nm light. This compensates for the phase distortion of the 800 nm transmitted light path caused by multilayer film reflection, providing the optical field conditions for constructing a dynamic defect activation and transport network. The nitrided surface layer of the above scheme not only significantly improves the surface energy of the substrate, ensuring the adhesion of the thin film deposition, but the introduced nitrogen element also forms a potential affinity with halide ions in large-size perovskite components in a chemical environment, providing a stable basis for the entire optical interface to be compatible with the component under test; thus, an activated substrate with specific surface energy and chemical properties is obtained. Based on a periodic structure with a quarter-wavelength optical thickness, it does not form a complete reflection of a certain wavelength, but utilizes multilayer film... The interference effect creates an asymmetric reflectivity distribution at the interface: for broadband composite light incident perpendicular to the interface, photons in the 450nm band are strongly reflected due to coherent constructive interference, forming a 450nm blue light reflection path; while photons with wavelengths greater than 500nm are mostly transmitted due to destructive interference, entering the next stage as a broadband residual beam; precisely matching the specific blue light energy required to excite iodine vacancy migration; compensating for the phase distortion of the 800nm ​​transmission path caused by multilayer film reflection, ensuring that the near-infrared light maintains wavefront consistency when spatially combining with the blue light, thereby achieving precise spatiotemporal coordination of dual-band excitation energy within the perovskite component; and providing ideal optical field conditions for constructing a dynamic defect activation and transport network.

The above scheme achieves refined spatial characterization of the electrical performance of perovskite modules through multi-module collaboration. The system first constructs a spatially resolved electrical contact network using a differentiated probe layout—a 10mm spacing with 20g pressure in the central region achieves wide coverage, while a 5mm spacing with 30g pressure in the edge region enhances local detection density, laying the physical contact foundation for testing. The bias scanning module simultaneously acquires the current-voltage dynamic response of a nine-point matrix under dual-band illumination, ensuring data stability through constant contact pressure, and obtaining nine sets of spatiotemporally correlated electrical characteristic curves. The data sequence reflects both the carrier transport characteristics of local regions and preserves the performance comparison relationship between different locations. The time parameter conversion module focuses on open-circuit voltage decay behavior, extracting carrier lifetime through the time parameter of the second derivative extremum point, transforming the time-domain electrical signal into a lifetime distribution set of nine regions. The final output can intuitively present the spatial non-uniformity of carrier recombination characteristics on the perovskite module surface, providing a clearly defined quantitative basis for material process optimization.

The time parameter conversion component of the above scheme works in concert to achieve high-precision calculation of carrier lifetime in current-voltage data sequences. First, the open-circuit voltage decay segment is extracted by the smooth splicing sub-component to construct a continuous and smooth decay trajectory. Then, the differential processing sub-component identifies the dynamic turning points in the decay process. Finally, the quantization relationship sub-component converts the time parameter into a carrier lifetime value. This achieves standardized processing of the entire process from raw data acquisition to lifetime parameter calculation, ensuring the reliability and reproducibility of the measurement results.

[0097] The initial set formation module is used to take the extracted open-circuit voltage attenuation segment as input and establish a node sequence based on each sampling time point; with two adjacent nodes as boundaries, it creates a cubic polynomial expression containing four undetermined coefficients for each interval, forming the initial piecewise cubic polynomial set.

[0098] The constraint confirmation module is used to apply continuity conditions to two adjacent piecewise cubic polynomials by using the node sequence as a connection constraint. The function values ​​of the two polynomials at the common node are equal. Secondly, the first derivative values ​​at the common node are equal, and the second derivative values ​​at the common node are equal. The system of equations is established through constraints.

[0099] The trajectory generation module is used to determine the specific coefficient values ​​of each piecewise cubic polynomial by solving the system of equations established by the continuity condition. The specific coefficient values ​​merge the independent polynomial segments into a composite curve with continuous first and second derivatives, generating a smooth decaying trajectory for differential operations.

[0100] Among them, a piecewise polynomial is constructed:

[0123] ;

[0124] Specifically:

[0125] ;

[0126] Now, the continuity equation and the boundary condition equation together constitute a closed system of linear equations with an equal number of unknowns and equations. By solving the complete system of linear equations, a unique numerical solution for the coefficients in all intervals is determined. Substituting the obtained coefficients back into the polynomial expression, these originally independent piecewise functions are merged into a complete composite curve with continuous first and second derivatives in the global domain, which is the final smooth decaying trajectory. The mathematical components (piecewise polynomials) that construct the curve are defined, and the rules for how the components are connected are defined (the system of continuity equations). However, the system is not yet closed. The boundary conditions close the system, and the specific shape of the components is determined by solving them, thus assembling the components into the final smooth trajectory according to the rules.

The initial set formation module divides the discrete sampling points into piecewise cubic polynomial intervals, laying the foundation for mathematical expression. The constraint confirmation module ensures a smooth transition between adjacent curve segments through continuity constraints on function values, first derivatives, and second derivatives. The trajectory generation module solves the constraint equations and ultimately outputs a composite decay curve with continuity of the second derivative. This fully realizes the transformation process from discrete data points to continuously differentiable curves, providing a mathematical foundation for differential operations that conforms to physical laws.

It calculates the relative position ratio of the initial carrier lifetime parameter within the upper and lower boundary intervals. The value of the relative position ratio is determined by dividing the difference between the initial carrier lifetime parameter and the lower boundary value by the difference between the upper and lower boundary values.

A calibration data set containing four key nodes is formed. The relative position ratio of the initial carrier lifetime parameter within the upper and lower boundary intervals is calculated. The value of the relative position ratio is determined by dividing the difference between the initial carrier lifetime parameter and the lower boundary value by the difference between the upper and lower boundary values. The weighted synthesis module is used to multiply the lower boundary calibration value by the complement of the ratio value and the upper boundary calibration value by the ratio value according to the obtained relative position ratio. The two products are added to obtain the final calibrated carrier lifetime value. After performing the calculations for nine spatial locations, the obtained initial carrier lifetime values ​​are spatially sorted according to the measurement location to form a carrier lifetime distribution set that completely corresponds to the nine-point matrix on the surface of the perovskite component. The time coefficient fusion module of the above scheme generates uncalibrated initial lifetime parameters by performing arithmetic multiplication of time coordinates and conversion coefficients, providing basic data input for calibration. The contact optical coupling calibration module uses a preset calibration table to establish a nonlinear mapping relationship between the initial lifetime parameter and the actual lifetime. By locating the numerical interval of the parameter, the boundary calibration value is extracted to form a four-node data set, and the relative position ratio of the parameter is determined by difference calculation, providing a calculation basis for weighted synthesis. The weighted synthesis module performs linear interpolation calculations based on the relative position ratio, weights and synthesizes the upper and lower boundary calibration values ​​proportionally, and outputs the final calibrated lifetime value. After processing the nine measurement positions in sequence, a carrier lifetime dataset that completely corresponds to the spatial distribution on the surface of the perovskite component is formed.

[0133] In summary, this embodiment completes the calculation and calibration process of carrier lifetime parameters from time coordinates to spatial distribution, realizing high-precision conversion and mapping of time-scale data to spatial lifetime parameters; the final output lifetime distribution set can accurately reflect the spatial heterogeneity characteristics of carrier lifetime on the surface of perovskite components.

It divides each axial length by 3 to obtain a tri-division spacing value of 100 mm. The division point locator calculates and records two position coordinates (100 mm and 200 mm) in the X-axis direction and two position coordinates (100 mm and 200 mm) in the Y-axis direction, forming four division point coordinate data. The region boundary generator combines the four division point coordinates with the component boundary coordinates, forming grid lines by connecting the division points, and finally outputs a set of boundary coordinates for nine square regions, each corresponding to a 100×100 mm detection unit. This solution achieves standardized encoding of the spatial position on the perovskite component surface. Its specific functional value is reflected in the fact that by setting the coordinate origin and boundary range, the actual 300×300 mm component surface is transformed into a calculable Cartesian coordinate system, providing a basis for spatial division. A uniformly distributed nine-square grid structure is generated based on equal division calculations, clearly defining the boundary coordinates of each 100×100 mm region to ensure the geometric accuracy and consistency of spatial division.

By parsing the instruction header data, the instructions are classified and stored in the corresponding buffer according to the region identification code.

[0174] The light intensity-to-current conversion component is used to read the light intensity compensation parameters of each buffer zone, convert the light intensity value of the 450nm band into the corresponding driving current value according to the pre-stored LED luminous efficacy characteristic curve, and convert the light intensity value of the 800nm ​​band into the corresponding driving current value at a ratio of 1.6, thereby generating a dual-band driving current parameter group for each region.

[0175] The current output execution component sends the dual-band drive current parameter set to the corresponding LED driver circuit sequentially according to the region identification code. The 450nm and 800nm ​​LED modules in each region synchronously receive the adjusted drive current, thereby adjusting the light intensity of each region.

The light intensity-current conversion component is used to read the light intensity compensation parameters of each buffer, and convert the light intensity value of the 450nm band into the corresponding driving current value according to the pre-stored LED luminous efficacy characteristic curve. At the same time, the light intensity value of the 800nm ​​band is converted into the corresponding driving current value according to a 1.6 times ratio, generating a dual-band driving current parameter group for each region. The current output execution component is used to send the dual-band driving current parameter group to the corresponding LED driving circuit in sequence according to the order of the region identification codes.
