A control method for a laminating device

Abstract

This invention provides a control method for a laminating apparatus. In this method, a light-emitting component in the laminating apparatus is controlled by a control system to emit light, a heating component to heat the component to be laminated, and a light-shielding component to shield the component from light. The control system controls an electronic load source meter to detect scan data of the component under heating conditions during both the illumination and shading periods, and feeds this scan data back to the control system. The control system obtains performance parameters of the component to be laminated based on the scan data. Based on these parameters, it determines whether the performance parameters have reached a target value. When the target value is reached, the control system controls the laminating apparatus to terminate the lamination process. Because this control method obtains the performance parameters of the component to be laminated during the lamination process, the lamination process can be terminated at the optimal power point, resulting in a laminated product with better performance.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and more specifically, to a control method for a laminating device. Background Technology

[0002] Perovskite solar cells are a new type of solid-state thin-film solar cell that uses organic-inorganic composite metal halide perovskite materials as photosensitizers. As a rising star in the field of solar cells, perovskite solar cells have received widespread attention since their inception. In the fabrication of large-area perovskite solar cells, solvent engineering is often used in combination with various film-forming strategies (such as air knife purging, vacuum flash evaporation, and antisolvent bath). This involves combining various organic solvents with different polarities and saturated vapor pressures to promote uniform and rapid nucleation of the large-area perovskite film. The film is then annealed and crystallized to form the final polycrystalline perovskite film. The quality of perovskite crystallization directly affects the power generation performance of the final perovskite solar cell.

[0003] Photovoltaic laminators are essential equipment for encapsulating solar cell modules. They create a sealed assembly, isolating moisture and air, by heating the encapsulation film (such as EVA or POE film), solar cells, and encapsulation glass under high-temperature, vacuum conditions. Currently, common photovoltaic laminators are relatively simple in function. They typically connect a vacuum pump to the upper and lower chambers of the laminator, evacuate both chambers, heat the lower chamber's base plate using heat transfer oil or heating wires, and pressurize the upper chamber's rubber plate cavity by inflating it. During the lamination process of perovskite solar cell modules, the perovskite film recrystallizes under heating and pressurization, especially at the buried interface of the perovskite solar cell. If this recrystallization occurs at the optimal power point, it is beneficial for improving the power output of the perovskite solar cell.

[0004] However, current lamination equipment cannot monitor the recrystallization process of the components to be laminated during the lamination process, and the crystallization of each component before lamination is different. Ultimately, it is difficult for the components to be laminated to complete lamination at the optimal power point, which is not conducive to improving the power and yield of the components to be laminated.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This invention provides a control method for a laminating device. To better illustrate this control method, this invention first describes the laminating device.

[0037] refer to Figure 1 , Figure 1 This is a schematic diagram of a lamination device provided in an embodiment of the present invention; see reference. Figure 2, Figure 2 This is a schematic cross-sectional view of a laminating device provided in an embodiment of the present invention; the laminating device includes:

[0038] The lamination cavity includes a first sub-cavity 01 and a second sub-cavity 02 disposed opposite to each other in a first direction M, and a transparent carrier 03 located between the first sub-cavity 01 and the second sub-cavity 02; the transparent carrier 03 is used to place the component 04 to be laminated; the first direction M is perpendicular to the plane where the transparent carrier 03 is located, and points from the first sub-cavity 01 to the second sub-cavity 02.

[0039] The first sub-cavity 01 includes a first region 05, a second region 06 and a third region 07 arranged sequentially in the first direction M. There is a gap between the first region 05 and the second region 06, and there is a gap between the second region 06 and the third region 07.

[0040] An electronic load source meter 08 and a light-emitting component 09 are located in the first region 05; the electronic load source meter 08 is connected to the component to be laminated 04 and is used to measure the lamination data of the component to be laminated 04; the light-emitting surface of the light-emitting component 09 is arranged opposite to the transparent carrier 03.

[0041] The heating component 10 is located in the second region 06; the light-shielding component 11 is located in the third region 07; the light-shielding component 11 is used to shield the component 04 to be laminated from light.

[0042] Specifically, such as Figure 2 As shown, the first sub-cavity 01 of the lamination chamber includes a first region 05, a second region 06, and a third region 07. It should be noted that the first region 05, the second region 06, and the third region 07 are virtual divisions. In order to better illustrate the position of the components set in the first sub-cavity 01, the position of the electronic load source meter 08 in the first region 05 is not specifically limited. When the range of the electronic load source meter 08 is within the IV curve scanning range of the component to be laminated 04, the IV curve can be scanned on the component to be laminated. The component to be laminated 04 can be a perovskite component.

[0043] The light-emitting surface of the light-emitting component 09 is set opposite to the transparent carrier 03, that is, the light-emitting surface of the light-emitting component 09 faces the transparent carrier 03. The heating component 10 in the second region 06 is provided with a support structure. The setting of the support structure allows there to be a certain gap between the light-emitting component 09 and the heating component 10 to avoid mutual interference. It should be noted that the support structure is not shown in the figure.

[0044] A transparent carrier 03 is also provided between the first sub-cavity 01 and the second sub-cavity 02 of the lamination cavity. The transparent carrier 03 can be a transparent glass carrier. The transparent carrier 03 is used to place the component 04 to be laminated. It has a certain thickness and mechanical strength. The carrier is set to be transparent. The light generated by the light-emitting component 09 in the first sub-cavity 01 can pass through the carrier and shine on the light-receiving surface of the component 04 to be laminated. The light-shielding component 11 in the third region 07 can block the light generated by the light-emitting component 09 and the heating component 10, so that the component 04 to be laminated is in a dark field.

[0045] Optionally, in another embodiment of the present invention, the heating component 10 includes an infrared heating lamp; it should be noted that the thermal radiation generated by the infrared heating lamp can heat the laminated component 04 through the transparent carrier 03, and the heating temperature at least meets the temperature required by the laminated component 04. For example, when the laminated component 04 is a perovskite component, the heating temperature at least meets 100℃-150℃.

[0046] refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a light-emitting component provided in an embodiment of the present invention; the light-emitting component 09 includes:

[0047] A plurality of first light-emitting units 09a and a plurality of second light-emitting units 09b are located on the light-emitting surface; the plurality of first light-emitting units 09a and the plurality of second light-emitting units 09b are arranged in an alternating array; the first light-emitting unit 09a has a first light intensity; the second light-emitting unit 09b has a second light intensity; the first light intensity and the second light intensity are different.

[0048] Specifically, the light-emitting surface of the light-emitting component 09 faces the transparent carrier 03. Multiple first light-emitting units 09a and multiple second light-emitting units 09b are arranged on the light-emitting surface. The first light-emitting unit 09a has a first light intensity, and the second light-emitting unit 09b has a second light intensity. The first light intensity and the second light intensity are different. When the first light-emitting unit 09a emits light of the first light intensity, the electron load source meter 08 performs an IV curve scan on the laminated component 04 to obtain first sub-scan data. When the second light-emitting unit 09b emits light of the second light intensity, the electron load source meter 08 performs an IV curve scan on the laminated component 04 to obtain second sub-scan data. The first sub-scan data and the second sub-scan data are different.

[0049] Light-emitting component 09 can be an LED light-emitting unit. There is no specific limitation on light-emitting component 09. The light intensity generated by light-emitting component 09 in the lamination cavity can meet the illumination intensity range of 500W / m. 2 -800W / m 2 For example, the light intensity can be 500W / m 2570W / m 2 720W / m 2 wait.

[0050] like Figure 2 As shown, the second sub-cavity 02 includes a pressure regulating component 12, which is disposed opposite to the transparent carrier 03 and is used to control the pressure of the second sub-cavity 02.

[0051] Specifically, the pressure regulating component 12 can be a rubber plate cavity. When the rubber plate cavity is inflated, it can increase the pressure of the second sub-cavity 02. The pressure range of the rubber plate cavity can be controlled according to the pressure requirements of different components to be laminated 04. For example, the pressure range of the rubber plate cavity can be controlled from -90kPa to -70kPa.

[0052] refer to Figure 4 , Figure 4 This is a schematic diagram of another lamination device provided in an embodiment of the present invention; the lamination device further includes:

[0053] A control system 13 is located outside the lamination cavity; the control system 13 is connected to the electronic load source meter 08, the light-emitting component 09, the heating component 10, the light-shielding component 11 and the pressure adjustment component 12 respectively.

[0054] Specifically, the control system 13 can control the electronic load source meter 08 to perform IV curve scanning on the component to be laminated 04, and the scan data obtained by the electronic load source meter 08 is fed back to the control system 13; the control system 13 can also control the light-emitting component 09 to emit light to illuminate the component to be laminated 04; the control system 13 can also control the heating component 10 to heat the component to be laminated 04; the control system 13 can also control the light-shielding component 11 to shield the component to be laminated 04; the control system 13 can also control the pressure adjustment component 12 to adjust the pressure of the second sub-cavity 02; it should be noted that the control system 13 can detect the lamination time, temperature, pressure, etc. of the lamination device, and can calculate the performance parameters of the component to be laminated 04 based on the scan data fed back by the electronic load source meter 08. It should be noted that all these scan data are the lamination data of the component to be laminated 04.

[0055] The light-shielding assembly 11 includes: an electrically controlled guide rail and a light-shielding plate located on the electrically controlled guide rail; the electrically controlled guide rail is connected to the control system 13.

[0056] Specifically, the electrically controlled guide rail is connected to the control system 13. The guide rail has a light-shielding plate, and the control system 13 can control the movement of the light-shielding plate. The light-shielding component 11 can control the component 04 to be laminated to be in a light-shielding state. (Refer to...) Figure 5 , Figure 5This is a cross-sectional structural diagram of another lamination device provided in an embodiment of the present invention; wherein the control system controls the electrically controlled guide rail to move the light-shielding plate, so that the light-shielding plate blocks the light generated by the light-emitting component 09 and the heating component 10, thereby placing the component 04 to be laminated in a dark field; the light-shielding component 11 can also control the component 04 to be laminated to be in an unshielded state, such as Figure 2 As shown, the control system 13 can control the electric guide rail to move the light shield so that the component to be laminated 04 can be illuminated by the light generated by the light-emitting component 09 and the heating component 10, thereby placing the component to be laminated 04 in a bright field.

[0057] It should be noted that the device for moving the sunshade includes, but is not limited to, an electrically controlled guide rail; it only needs to be able to connect to the control system 13 to move the position of the sunshade.

[0058] The lamination device further includes a vacuum pump; the vacuum pump is connected to the control system 13 and the lamination cavity respectively, and is used to evacuate the lamination cavity.

[0059] Specifically, the vacuum pump is located outside the lamination chamber and connected to the lamination chamber. Since the lamination chamber needs to be evacuated when the lamination device is laminating, the control system 13 is connected to the vacuum pump. When evacuation is required, the control system 13 controls the vacuum pump to evacuate the lamination chamber.

[0060] The lamination device further includes a pneumatic device, which is connected to the control system 13 and is used to control the second sub-cavity 02 to be in an open or closed state.

[0061] Specifically, when the laminating device performs lamination, the component to be laminated 04 needs to be placed on the transparent carrier 03 in the second sub-cavity 02. The control system 13 controls the pneumatic device to open the second sub-cavity 02. After the component to be laminated 04 is placed in, the control system 13 controls the pneumatic device to close the second sub-cavity.

[0062] Based on the above-described lamination apparatus, the present invention provides a control method for the lamination apparatus, with reference to... Figure 6 , Figure 6 A flowchart illustrating a control method for a laminating apparatus provided in an embodiment of the present invention; as shown. Figure 2 As shown, Figure 4 As shown, the lamination device includes an electronic load source meter 08, a light-emitting component 09, a heating component 10, a light-shielding component 11, and a control system 13. The control method includes:

[0063] S101: The working state of the heating component 10, the light-emitting component 09 and the light-shielding component 11 is controlled by the control system 13; the heating component 10 heats the laminating component 04, the light-emitting component 09 irradiates the laminating component 04 multiple times during the heating process, and the light-shielding component 11 shields the laminating component 04 multiple times during the heating process.

[0064] Optionally, in another embodiment of the present invention, the laminating apparatus further includes a pneumatic device, and the control method further includes:

[0065] The control system 13 controls the working state of the pneumatic device to open or close the second sub-cavity.

[0066] Before proceeding with this step, preparatory work for lamination is performed. First, the positive and negative leads of the component to be laminated 04 are connected to the electronic load source meter 08. The control system 13 controls the pneumatic device to open the second sub-cavity 02. After opening, the component to be laminated 04 connected to the electronic load source meter 08 is placed on the surface of the transparent carrier 03 on one side of the second sub-cavity 02. After placement, the control system 13 controls the pneumatic device to close the second sub-cavity 02. After closing, other conditions in the lamination cavity can be controlled to laminate the component to be laminated 04.

[0067] Optionally, in another embodiment of the present invention, the lamination apparatus further includes a vacuum pump and a lamination chamber, and the control method further includes, before heating the lamination assembly 04 based on the heating assembly 10:

[0068] The vacuum pump is controlled by the control system 13 to perform vacuuming on the lamination chamber.

[0069] Specifically, the control system 13 controls the vacuum pump to be in working state. That is, the control system 13 controls the vacuum pump to evacuate the lamination chamber. This evacuation is performed on both the first sub-chamber 01 and the second sub-chamber 02. Taking the perovskite component to be laminated 04 as an example, the vacuum level is controlled to reach a vacuum range of 1 Pa to 5 Pa.

[0070] When the lamination chamber is in a vacuum state, the control system 13 controls the heating component 10 to heat the lamination component 04. Here, the heating component 10 can be an infrared heating lamp. The heat radiation of the infrared heating lamp can pass through the transparent carrier 03 to heat the lamination component 04. Taking the lamination component 04 as a perovskite component as an example, the heating temperature is preferably 120°C to 150°C.

[0071] Optionally, in another embodiment of the present invention, the lamination apparatus further includes a pressure regulation component 12, the lamination cavity includes a first sub-cavity 01 and a second sub-cavity 02, and before the light-emitting component 09 irradiates the component to be laminated 04 multiple times during the heating process, the control method further includes:

[0072] The control system 13 controls the working state of the pressure regulation component 12 to change the pressure of the second sub-cavity 02 and pressurize the component 04 to be laminated.

[0073] Specifically, the control system 13 controls the pressure regulating component 12 to be in working state. Here, the pressure regulating component 12 can be a rubber plate cavity. The control system 13 controls the rubber plate cavity to be inflated. When inflated, the pressure in the second sub-cavity 02 will increase, thereby pressurizing the component to be laminated 04. According to the pressure required by the component to be laminated 04, the pressure range is selected. Taking the component to be laminated 04 as a perovskite component as an example, -90kPa to -70kPa can be selected. At this time, the lamination preparation work is completed, and the lamination of the component to be laminated begins. During the vacuuming, heating, and pressurizing process of the lamination device, the component to be laminated 04 is irradiated multiple times based on the light-emitting component 09, and during the vacuuming, heating, and pressurizing process of the lamination device, the component to be laminated 04 is shielded multiple times based on the light-shielding component 11.

[0074] S102: Based on the control system 13, control the working state of the electronic load source meter 08 so that the electronic load source meter 08 obtains the scanning data of the component to be laminated 04 during the irradiation period and the shading period, and feeds the scanning data back to the control system 13.

[0075] Optionally, in another embodiment of the invention, reference is made to... Figure 7 , Figure 7 This is a flowchart illustrating another control method for a laminating apparatus provided in an embodiment of the present invention; based on the control system 13 controlling the working state of the electronic load source meter 08, so that the electronic load source meter 08 obtains scan data of the component to be laminated 04 during the irradiation period and the shading period, and feeds back the scan data to the control system 13, including:

[0076] S111: Based on the control system 13, the electronic load source table 08 is controlled to scan the component 04 to be laminated during the irradiation period to obtain multiple first scan data, and the multiple first scan data are fed back to the control system 13.

[0077] Optionally, the light-emitting component includes: a plurality of first light-emitting units 09a and a plurality of second light-emitting units 09b, wherein the first light-emitting units 09a have a first light intensity, and the second light-emitting units 09b have a second light intensity, and the first light intensity and the second light intensity are different; the step of irradiating the component to be laminated multiple times during the heating process includes:

[0078] Based on the control system 13, the first light-emitting unit 09a and the second light-emitting unit 09b are controlled to alternately emit light beams multiple times to irradiate the component 04 to be laminated.

[0079] Specifically, the first light-emitting unit 09a and the second light-emitting unit 09b have different light intensities. The laminating assembly 04 is irradiated with light of the first light intensity generated by the first light-emitting unit 09a and light of the second light intensity generated by the second light-emitting unit 09b, respectively. The control system 13 controls the first light-emitting unit 09a and the second light-emitting unit 09b to emit light alternately. The emitted light passes through the transparent carrier 03 and irradiates the laminating assembly 04. During the time period when the first light-emitting unit 09a emits light of the first light intensity, the control system 13 controls the electronic load source meter 08 to perform IV curve scanning on the laminating assembly to obtain first sub-scan data. During the time period when the second light-emitting unit 09b emits light of the second light intensity, the control system 13 controls the electronic load source meter 08 to perform IV curve scanning on the laminating assembly to obtain second sub-scan data. The electronic load source meter 08 feeds back the obtained first sub-scan data and second sub-scan data to the control system 13. It should be noted that the first scan data includes the first sub-scan data and the second sub-scan data. Multiple alternating irradiation scans are performed during the lamination process to obtain multiple first scan data.

[0080] It should be noted that the light-emitting component 09 does not emit light continuously, but at intervals. The frequency of these intervals is adjustable and not specifically limited.

[0081] S112: Based on the control system 13, the electronic load source meter 08 is controlled to scan the component 04 to be laminated during the shading period to obtain multiple second scan data, and the multiple second scan data are fed back to the control system 13.

[0082] Optionally, in another embodiment of the present invention, the light-shielding assembly 11 includes: an electrically controlled guide rail and a light-shielding plate located on the electrically controlled guide rail, wherein the multiple light-shielding operations performed on the assembly to be laminated during the heating process include:

[0083] The control system 13 controls the working state of the electrically controlled guide rail to change the position of the light-shielding plate on the electrically controlled guide rail and perform multiple light-shielding operations on the component to be laminated.

[0084] Specifically, the control system 13 controls the electronically controlled guide rail to be in working state and moves the position of the light-shielding plate so that the light-shielding plate blocks the light of the component to be laminated 04 for a short period of time. At this time, the component to be laminated 04 is in the dark field. During this light-shielding period, the control system 13 controls the electronic load source meter 08 to perform dark field IV curve scanning to obtain the second scan data. The electronic load source meter 08 feeds back the third scan data obtained by scanning to the control system 13. Multiple light-shielding scans are performed during the lamination process to obtain multiple second scan data.

[0085] S103: The control system 13 obtains the electrical parameters of the component 04 to be laminated based on the scanning data. When the electrical parameter value reaches the target value, the control system 13 controls the lamination device to end the lamination process.

[0086] In this step, the control system 13 substitutes the first scan data into formula 1:

[0087]

[0088] The series resistance value of component 04 to be laminated during the lamination process is calculated within the illumination period. Since multiple alternating irradiation scans are performed during the lamination process, the series resistance value in multiple different time periods can be calculated.

[0089] The control system 13 substitutes the second scan data into formula 2:

[0090]

[0091] The parallel resistance value of the component 04 to be laminated during the shading period is calculated, and the leakage current value of the component 04 to be laminated is read from the second scan data. Since the shading is performed multiple times during the lamination process, the parallel resistance value in multiple different time periods can be calculated, and the leakage current value in multiple different time periods can be read at the same time.

[0092] The entire scanning and calculation process is relatively fast and can be completed within tens of seconds. Therefore, when the obtained series resistance, parallel resistance, and leakage current values ​​all reach the target values, the control system 13 controls the components in the lamination device to stop working, thereby ending the lamination process.

[0093] It should be noted that the target value is the minimum series resistance and leakage current, and the maximum resistance. At this time, the recrystallization effect of the module to be laminated 04 is optimal. Taking the module to be laminated 04 as a perovskite module as an example, the interface of each functional layer of the perovskite module has good contact at this time.

[0094] During the lamination process, the performance parameters such as series resistance, parallel resistance, and leakage current of the component to be laminated 04 are detected. Under the premise of ensuring the lamination effect, the control system 13 comprehensively analyzes the various performance parameters and ends the lamination process at the time point that is most conducive to maximizing the power of the component to be laminated 04, so as to obtain a laminated product with better performance.
