Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solar cells, and in particular to a two-terminal tandem cell quantum response data correction method and device, electronic equipment and storage medium. BACKGROUND

[0002] Quantum response testing (Quantum Efficiency) is an important test method for evaluating the performance of optoelectronic devices, which refers to the ratio of the number of external collectable carriers generated by an optoelectronic device (such as a solar cell, a photodetector, etc.) under certain conditions to the number of photons incident on the device surface, usually expressed in percentage.

[0003] In QE testing, monochromatic light is used to irradiate the optoelectronic device, and the wavelength range of these monochromatic lights usually covers the working spectral range of the device. By measuring the photocurrent generated by the device under irradiation of monochromatic light of different wavelengths, combined with the known incident light power and wavelength information, the external quantum efficiency corresponding to each wavelength can be calculated.

[0004] A two-terminal tandem cell is a solar cell that connects two sub-cells with different band gap widths in series and stacks them in the vertical direction, i.e., the direction of light incidence, so that they are connected into one whole, and only has two electrodes for outputting electric energy.

[0005] In the process of QE testing of a two-terminal tandem cell, due to the characteristics of the cell, the two sub-cells need to be tested separately, and an additional bias light needs to be applied to the other non-tested sub-cell during the testing process. This additional light source may have an impact on the final cell test results. This impact can be mainly divided into three parts, namely, light transmission problem, shunt problem, and light emission coupling problem.

[0006] In the existing test method, specific correction schemes have been proposed for the shunt and light emission coupling problems, but no correction method has been proposed for the light transmission problem. SUMMARY

[0058] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application in order to make the technical personnel in the technical field better understand the technical solutions. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein.

[0060] Figure 1 A flowchart of a two-end laminated battery quantum response data correction method provided by the embodiment of the present application, the embodiment can be applicable to the correction of the light transmission problem generated in the quantum response test process of the two-end laminated battery. The method can be executed by a two-end laminated battery quantum response data correction device. The correction device can be realized in the form of hardware and / or software, and can be configured in any electronic device with communication function. Referring to Figure 1 The method comprises:

[0061] S110, judging whether the two-end laminated battery quantum response data is abnormal data.

[0062] Specifically, determining whether the quantum response data of the two-terminal tandem cell is abnormal data refers to analyzing the quantum efficiency related data generated by the tandem cell under illumination of light of different wavelengths to determine whether these data deviate from the normal range or present characteristics that do not conform to expectations. The tandem cell is a solar cell stacked by multiple sub-cells of different materials, and its quantum response refers to the photoelectric conversion capability of the cell to light of different wavelengths. The quantum efficiency of the tandem cell is generally calculated by measuring the short-circuit current generated by the tandem cell under illumination of monochromatic light of different wavelengths, and then obtaining the quantum response data. These data can reflect the absorption of light of different wavelengths and the carrier collection of each sub-cell inside the tandem cell. For example, when testing the to-be-tested sub-cell, bias light with the same spectrum but different light intensities is applied on the non-tested sub-cell. If the quantum response data of the to-be-tested sub-cell measured by the bias light with different light intensities is inconsistent and changes, it means that the to-be-tested sub-cell is affected by the bias light during the testing process, and the data needs to be corrected. Alternatively, the normal quantum response data range can be determined based on theoretical calculation, past experimental experience or industry standards by comparison with standard values or expected values. If the measured quantum response data of the two-terminal tandem cell is outside this range, it means that it may be abnormal. For example, the quantum efficiency at a certain wavelength is significantly lower or higher than the typical value of the same type of cell. Alternatively, the trend of the quantum response data with the change of the wavelength can also be observed by data trend analysis to see whether it conforms to the normal law. In normal cases, the quantum response curve will have a specific change trend in different wavelength regions, such as gradually rising in some wavelength range, remaining relatively stable or gradually decreasing in other wavelength range, etc. If the data trend is obviously abnormal, such as sudden jump, discontinuity or far away from the theoretical curve, it means that the measured data may be abnormal. By judging whether the quantum response data of the two-terminal tandem cell is abnormal, the performance status of the cell can be understood, and possible problems such as material defects and imperfect process can be found out, thereby providing a basis for improving the cell design and production process to improve the photoelectric conversion efficiency and stability of the tandem cell.

[0063] S120, if the quantum response data of the two-terminal tandem cell is abnormal data and the abnormal data is caused by the light transmission problem, correcting the abnormal data caused by the light transmission problem.

[0064] Specifically, the light transmission problem of the stacked cell can be caused by various factors, such as insufficient light transmission of the packaging material of the cell, gaps or impurities between the internal layers affecting light transmission, stains or scratches on the surface, etc. These problems can change the propagation and absorption of incident light inside the cell, and thus cause abnormal quantum response data. By increasing the bias light intensity, the changes of the quantum response data of the to-be-tested sub-cell in the entire test interval and the monochromatic light wavelength interval of its own and the quantum response of the non-test sub-cell are observed, the source of the abnormal data is determined, the quantum response data of the two-end stacked cell is abnormal, and the source of the abnormal data includes the light transmission problem, and the abnormal data generated by the light transmission problem is corrected according to the preset formula.

[0065] The technical scheme provided by the embodiment of the present application determines whether the quantum response data of the two-end stacked cell is abnormal data, and corrects the abnormal data generated by the light transmission problem when the quantum response data of the two-end stacked cell is abnormal data and the abnormal data is generated at least due to the light transmission problem. The influence of the light transmission problem is eliminated, so that more accurate quantum efficiency values can be obtained, which is more in line with the actual situation and is beneficial to further device evaluation or process debugging.

[0066] In some other embodiments, optionally, the two-end stacked cell includes a first sub-cell and a second sub-cell; S110 specifically includes:

[0067] When testing the quantum response data of the first sub-cell, the second sub-cell is applied with bias light with the same spectrum but different light intensities. If the measured quantum response data of the first sub-cell deviates and the deviation exceeds a preset deviation, it is determined that the quantum response data of the first sub-cell is abnormal data.

[0068] The preset deviation can be preset according to the test requirement. In the embodiment of the present application, a crystalline silicon sub-cell is taken as the first sub-cell and a perovskite sub-cell is taken as the second sub-cell as an example for description.

[0069] For example, when testing the crystalline silicon sub-cell, bias light with the same spectrum but different light intensities is applied to the perovskite sub-cell. After applying bias light with different light intensities, the quantum response data of the crystalline silicon sub-cell measured under every two intensities of bias light is inconsistent, a deviation occurs, and the deviation exceeds a preset deviation, such as 1%. It is indicated that the crystalline silicon sub-cell is affected by the bias light during the test, because theoretically the test result of the crystalline silicon cell is determined by monochromatic light, and the bias light should have no effect on the crystalline silicon cell. However, in practice, if the bias light intensity is changed, the test result of the crystalline silicon cell changes, which indicates that there is an error in the test result, and the real result needs to be obtained after processing. Therefore, the data needs to be corrected. The deviation can be calculated according to the average value and the standard deviation; the average value is calculated by the following formula:

[0070] wherein, is the average value, and n is the number of tests.

[0071] The standard deviation is calculated by the following formula:

[0072] ; is the standard deviation.

[0073] The deviation is calculated according to the average value and the standard deviation by the following formula:

[0074] ; is the deviation.

[0075] Figure 2 is a flowchart of another correction method of quantum response data of a two-end stacked battery provided by an embodiment of the present application, which further refines the foregoing embodiment on the basis of the foregoing embodiment. Referring to FIG. 8, the method includes the following steps. Figure 2 Optionally, before S120, the method further includes:

[0076] S210, determining the source of the abnormal data.

[0077] Specifically, when the bias light intensity is increased, if the quantum response data of the first sub-cell is increased in the entire monochromatic light wavelength interval, and the increase values in the monochromatic light wavelength interval of the second sub-cell quantum response and the monochromatic light wavelength interval of the first sub-cell quantum response are equal, it is determined that the abnormal data is caused by the light transmission problem.

[0078] Exemplarily, when the bias light intensity is increased, if the quantum response data of the crystalline silicon sub-cell is increased in the entire test interval, and the increase values in the perovskite sub-cell response interval and the crystalline silicon sub-cell response interval are equal, it is determined that the abnormal data is caused by the light transmission problem. As shown in FIG. 6, Figure 3 Figure 3 is a data abnormality curve graph caused by a light transmission problem. The abscissa is the monochromatic light wavelength, and the ordinate is the quantum efficiency.

[0079] When the bias light intensity is increased, if the increase value of the quantum response data of the first sub-cell in the monochromatic light wavelength interval of the second sub-cell quantum response is increased, and the increase value in the monochromatic light wavelength interval of the first sub-cell quantum response is decreased, it is determined that the abnormal data is caused by the non-light transmission problem.

[0080] The non-light transmission problem includes a shunt problem or a light emission coupling problem.

[0081] ​Exemplarily, when the bias light intensity is increased, if the increase value of the quantum response data of the crystalline silicon sub-cell in the perovskite sub-cell response interval is increased, and the increase value in the crystalline silicon sub-cell response interval is decreased, it indicates that the abnormal data is caused by the shunt problem or the light emission coupling problem, and the abnormal data caused by the shunt problem or the light emission coupling problem is not corrected by the embodiment of the present application. For example, Figure 4 as shown in Figure 4 , is a data abnormality graph caused by a non-transmission problem.

[0082] In some other embodiments, S120 specifically includes:

[0083] a. The quantum response data of the first sub-cell measured at the preset monochromatic light wavelength The quantum response data of the first sub-cell includes: , There is a relationship as follows:

[0084] Formula (1)

[0085] In the formula, is the quantum response data caused by the shunt problem or the light emission coupling problem, is the quantum response data caused by the transmission problem, is the quantum response data caused by the monochromatic light, and the subscript n represents the test case of applying different bias light intensities.

[0086] Wherein, the preset monochromatic light wavelength is any wavelength in the perovskite sub-cell response interval.

[0087] b. Subtract the quantum response data of the first sub-cell applied with different bias light intensities, then:

[0088] Formula (2)

[0089] c. For the transmission problem, there is a relationship as follows:

[0090] Formula (3)

[0091] For the shunt problem or the light emission coupling problem, there is a relationship as follows:

[0092] Formula (4)

[0093] Wherein, is the proportional factor of the transmission problem, is the proportional factor of the shunt problem or the light emission coupling problem, is an exponential factor, is the corresponding bias light intensity;

[0094] d. Formula (3) and Formula (4) are brought into Formula (2) to obtain:

[0095] Formula (5)

[0096] e. At least four tests are performed, and the proportion factor of the light transmission problem is calculated by Formula (5) , the proportion factor of the shunt problem or the light emission coupling problem , and the exponential factor ;

[0097] f. According to the proportion factor of the light transmission problem , any bias light intensity , monochromatic light wavelength , quantum response data of the light transmission problem under the monochromatic light wavelength , the following relationship exists:

[0098] Formula (6);

[0099] g. The measured quantum response data of the first sub-cell under the preset monochromatic light wavelength is corrected by using the following formula:

[0100] Formula (7).

[0101] Optionally, the lower limit value of the bias light intensity accounts for at least 80% of the upper limit value of the bias light intensity.

[0102] Specifically, the difference between different bias light intensities applied in the test should not be too large, and the lowest intensity should account for at least 80% of the highest intensity.

[0103] Optionally, after S110, the method further comprises:

[0104] If the quantum response data of the two-end stacked cell is abnormal data, and the abnormal data is caused by the light transmission problem and the non-light transmission problem, the abnormal data caused by the light transmission problem is corrected first, and then the abnormal data caused by the non-light transmission problem is corrected.

[0105] Specifically, multiple tests with changing light intensity are performed, and if the abnormal data changes differently between each two tests, it indicates that the abnormal data is caused by the superposition of the light transmission problem and the non-light transmission problem, and the correction of the light transmission problem needs to be performed first, and then the non-light transmission problem is corrected according to the conventional method. For example, Figure 5 、 Figure 6 as shown in Figure 5 is a data abnormality curve diagram caused by the superposition of the light transmission problem and the non-light transmission problem, Figure 6The abnormal data curve generated by superimposition of the light transmission problem and the non-light transmission problem.

[0106] The correction method of the quantum response data of the two-end stacked battery provided in the application is specifically introduced below with a specific embodiment.

[0107] 1. Determine whether the quantum response data of the two-end stacked battery needs to be corrected.

[0108] When testing the crystalline silicon sub-cell, bias light with the same spectrum but different light intensities is applied on the perovskite sub-cell. If the measured quantum response data of the crystalline silicon sub-cell changes, it indicates that the crystalline silicon sub-cell is affected by the bias light during the test, and the data needs to be corrected.

[0109] 2. Determine the source of the abnormal data.

[0110] When the bias light intensity is increased, if the quantum response data of the first sub-cell increases in the entire single-color light wavelength range, and the increase values in the single-color light wavelength range of the second sub-cell quantum response and the single-color light wavelength range of the first sub-cell quantum response are equal, it indicates that the abnormal data is generated by the light transmission problem.

[0111] When the bias light intensity is increased, if the increase value of the quantum response data of the first sub-cell in the single-color light wavelength range of the second sub-cell quantum response increases, and the increase value in the single-color light wavelength range of the first sub-cell quantum response decreases, it indicates that the abnormal data is generated by the shunt problem or the light emission coupling problem. The embodiment of the application does not correct the abnormal data generated by the shunt problem or the light emission coupling problem.

[0112] Perform multiple tests with changing light intensity. If the abnormal data changes differently between each two tests, it indicates that the abnormal data is generated by superimposition of the light transmission problem and the non-light transmission problem, and the light transmission problem needs to be corrected first, and then the non-light transmission problem is corrected according to the conventional method.

[0113] 3. Correction method.

[0114] A specific wavelength in the response range of the perovskite sub-cell is used, for example, 500 nm. The quantum response data of the crystalline silicon sub-cell measured at this point is composed of three parts, the response data generated by light emission coupling (the embodiment of the application takes the light emission coupling problem as an example to participate in the correction process), the response data generated by the light transmission phenomenon, the response data generated by the single-color light, wherein the response data generated by the single-color light is the target to be measured, and the subscript n represents the test situation under different bias light intensities. The quantum response data of the crystalline silicon sub-cell has the following relationship:

[0115] Equation (1)

[0116] After several tests and subtraction of the results, we have:

[0117] Equation (2)

[0118] For the light transmission problem, there is a linear proportional relationship between the bias light intensity and the additional photocurrent response, and the proportional coefficient can be considered as a constant value within a certain range. Here, we require that the bias light intensity used in the test should not differ too much, and the lowest intensity should be at least 80% of the highest intensity, so that the difference in abnormal spectral response under different bias light intensities can be calculated. For the light emission coupling problem, there is an exponential relationship between the bias light intensity and the additional photocurrent response, and the proportional coefficient will not change within a certain range, so the following equation can be derived, where is the proportional factor of the light transmission problem, is the proportional factor of the light emission coupling problem, is the exponential factor,

[0119] is the corresponding bias light, then the following relationship is obtained:

[0120] Equation (3)

[0121] Equation (4)

[0122] Substituting Equation (3) and Equation (4) into Equation (2), we can obtain:

[0123] Equation (5)

[0124] At least four tests are performed, and three equations can be constructed according to the above equation to calculate , , three unknowns.

[0125] After calculating , the size of the additional quantum response caused by the light transmission problem under a certain bias light intensity can be further calculated, as shown in Equation (6). Since the wavelength and intensity of the bias light do not change during the test of the crystalline silicon sub-cell, the abnormal quantum response caused by the light transmission phenomenon at all wavelengths is equal. Therefore, only the value needs to be subtracted from the full waveband to eliminate the influence of the light transmission phenomenon, as shown in Equation (7).

[0126] Equation (6)

[0127] Equation (7)

[0128] Whether the battery is affected by other problems, the impact of the light transmission problem can be eliminated according to the above method.
