Description

Technical Field

[0001] This application relates to the field of photovoltaic cell technology, specifically to a testing device. Background Technology

[0002] Perovskite solar cells are a type of solar cell that uses perovskite-type organometal halide semiconductors as light-absorbing materials. During the production process, laser P1 etching is required. Laser P1 etching occurs after the deposition of transparent conductive electrodes (TCO) and before the deposition of the electron transport layer (ETL). The main function of laser P1 etching is to form multiple independent strip conductive electrodes on the transparent conductive electrodes by laser scribing. These strip conductive electrodes are the basis of the cell circuit structure, which helps to realize the series connection of the cells and increase the voltage.

[0003] In actual production, due to errors and other reasons, incomplete laser etching of P1 may occur, meaning the transparent conductive electrode is not fully penetrated, failing to form insulation between the strip conductive electrodes. This results in the two electrodes, which should be electrically isolated, becoming conductive, leading to the failure of the corresponding sub-cell. Currently, detecting the continuity between the strip conductive electrodes is cumbersome and does not provide intuitive results. Utility Model Content

[0004] In view of this, this application provides a detection device that can more intuitively determine whether there is energization between adjacent strip conductive electrodes of a perovskite solar cell, making the detection operation simpler and more convenient to complete.

[0025] All of the conductive pins are disposed on the crossbeam and extend downward from the bottom surface of the crossbeam; all of the indicator lights are disposed on the top surface and / or side surface of the crossbeam; the first direction is the length direction of the crossbeam.

[0026] Optionally, the above-mentioned detection device further includes:

[0027] The first drive motor is mounted on the base and is used to drive the platform to move on the guide rail or to drive the turntable to rotate.

[0033] The detection device provided in this application includes a support component and a mounting component disposed on the support component. The mounting component is equipped with multiple conductive pins and multiple indicator lights electrically connected one-to-one with these conductive pins. Adjacent indicator lights are respectively connected to different electrodes of a power source. When detecting whether there is energization between adjacent strip-shaped conductive electrodes formed by laser P1 etching on the conductive substrate of a perovskite solar cell, the conductive substrate is placed on the support component. The mounting component and / or the support component drive the multiple conductive pins to make one-to-one conductive contact with the multiple strip-shaped conductive electrodes on the conductive substrate. Since the indicator lights are electrically connected to the conductive pins and to the power source, each strip-shaped conductive electrode, each conductive pin, and each indicator light forms a series conductive structure with the power source. If two adjacent conductive strips are energized (i.e., not insulated from each other), the two series-connected conductive structures will be connected to form a conductive circuit, causing the two adjacent indicator lights to illuminate. If the two adjacent conductive strips are insulated from each other, no conductive circuit will be formed, and the two adjacent indicator lights will remain off. In this way, the inspector can directly observe whether the two adjacent indicator lights are lit to determine the laser P1 etching effect of the two adjacent conductive strips. Furthermore, the inspector can directly determine which conductive strips have failed the laser P1 etching based on the illuminated indicator lights. This allows the inspector to obtain the test results more intuitively, making the inspection operation simpler and more convenient. Attached Figure Description

[0044] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] In the production of perovskite solar cells, a layer of transparent conductive electrodes needs to be deposited on a transparent glass plate to form a conductive substrate (the conductive substrate is a semi-finished product of the perovskite solar cell, also known as an ITO substrate, Indium Tin Oxide). The transparent conductive electrodes also need to be laser-etched (P1 etching), which involves laser scribing. By etching multiple parallel straight lines on the transparent conductive electrodes, a complete layer of transparent conductive electrodes is divided into multiple parallel strip conductive electrodes. Since these strip conductive electrodes form the basic circuit structure that divides the entire perovskite solar cell into multiple sub-cells, they need to be insulated from each other to prevent sub-cell failure. However, in actual production, due to incomplete laser P1 etching (i.e., the laser does not completely separate the transparent conductive electrodes in the thickness direction during scribing), there may be cases where adjacent strip conductive electrodes are still energized. Therefore, it is necessary to detect the energization between adjacent strip conductive electrodes.

[0046] In response to the above situation, such as Figures 1-5 As shown, this application embodiment provides a detection device specifically used to detect whether there is electrical conduction between adjacent strip-shaped conductive electrodes 6 formed by laser P1 etching on the conductive substrate 5 of a perovskite solar cell (in actual production, this conductive substrate 5 can be entirely transparent, i.e., a transparent conductive substrate, or it can be an opaque conductive substrate). The detection device mainly includes multiple conductive needles 1, multiple indicator lights 2, a support component 3, and a mounting component 4. The multiple conductive needles 1 are disposed on the mounting component 4 and are used for one-to-one conductive contact with multiple parallel strip-shaped conductive electrodes 6 of the conductive substrate 5 placed on the support component 3. The multiple indicator lights 2 are also disposed on the mounting component 4 and are electrically connected one-to-one with all the conductive needles 1. Any two adjacent indicator lights 2 are electrically connected to different electrodes of the power supply, i.e., among all the indicator lights 2, such as... Figure 1 As shown, indicator lights 2 with odd-numbered sequences are all connected to the positive terminal of the power supply, and indicator lights 2 with even-numbered sequences are all connected to the negative terminal of the power supply. Alternatively, the arrangement can be reversed, i.e., indicator lights 2 with odd-numbered sequences are all connected to the negative terminal of the power supply, and indicator lights 2 with even-numbered sequences are all connected to the positive terminal of the power supply. The supporting component 3 and the mounting component 4 constitute the main structure of the detection device. The supporting component 3 is used to support the conductive substrate 5 to be detected during the detection process, and the mounting component 4 is used to install all conductive needles 1 and all indicator lights 2. The supporting component 3 and / or the mounting component 4... It is also necessary to enable relative movement between the conductive substrate 5 to be tested and all the conductive needles 1 (the movement methods include the carrier component 3 driving the conductive substrate 5 to translate and the mounting component 4 driving the conductive needles 1 and the indicator light 2 to rise and fall, the carrier component 3 driving the conductive substrate 5 to rise and fall and the mounting component 4 driving the conductive needles 1 and the indicator light 2 to translate, the carrier component 3 driving the conductive substrate 5 to translate and rise and fall, and the mounting component 4 driving the conductive needles 1 and the indicator light 2 to translate and rise and fall), so that the conductive needles 1 can make smooth one-to-one conductive contact with the strip conductive electrode 6 to ensure the normal progress of the test.

[0047] In the aforementioned detection device, since the indicator light 2 is electrically connected to the power supply, and the indicator light 2 is also electrically connected one-to-one to the conductive needle 1, during the detection process, when the conductive needle 1 makes one-to-one conductive contact with the strip conductive electrode 6, the strip conductive electrode 6, the conductive needle 1, and the indicator light 2 constitute a series conductive structure electrically connected to the positive or negative terminal of the power supply. If two adjacent strip conductive electrodes 6 are electrically connected (i.e., energized) due to incomplete etching by laser P1, the two adjacent series conductive structures will connect to form a conductive circuit, allowing current to flow smoothly from the positive to the negative terminal of the power supply. The two indicator lights 2 in the conductive circuit will then illuminate. Conversely, if... If two adjacent strip conductive electrodes 6 are completely etched by laser P1 and therefore not electrically connected, the two adjacent series conductive structures cannot form a conductive loop. Current cannot flow from the positive to the negative terminal of the power supply, and the two adjacent indicator lights 2 will not illuminate. Thus, inspectors can directly determine whether the laser P1 etching of the two adjacent strip conductive electrodes 6 is complete, i.e., whether insulation isolation has been achieved, simply by observing whether the two adjacent indicator lights 2 are lit. Compared to the existing method of detecting the resistance value of two adjacent strip conductive electrodes, this method provides a more intuitive result without comparing resistance values, making the inspection operation simpler and more convenient. Furthermore, since the indicator lights 2 are electrically connected one-to-one with the strip conductive electrodes 6, by observing which indicator lights 2 are lit, it is possible to directly determine which strip conductive electrodes 6 are not completely etched by laser P1, allowing for faster identification of defects in the perovskite solar cell and facilitating subsequent rework and repair.

[0048] In optional embodiments, such as Figures 1-4 As shown, the number of conductive needles 1 is greater than or equal to the number of strip conductive electrodes 6. That is, in the detection device provided by this application, the number of conductive needles 1 is not less than the total number of strip conductive electrodes 6 on a single conductive substrate 5, thereby enabling the detection device to simultaneously detect all strip conductive electrodes 6 on the same conductive substrate 5, thus improving detection efficiency and simplifying the detection steps. Alternatively, without considering the above effects, the number of conductive needles 1 can be less than the total number of strip conductive electrodes 6 on a single conductive substrate 5, and the detection of all strip conductive electrodes 6 can be completed in multiple steps during the detection process.

[0049] like Figures 1-4As shown, in the detection device of this application, all conductive needles 1 and all indicator lights 2 are arranged on the mounting assembly 4 along a first direction. That is, all conductive needles 1 are arranged in a row along a straight line, and similarly, all indicator lights 2 are also arranged in a row along a straight line, and the straight line formed by the arrangement of indicator lights 2 is parallel to the straight line formed by the arrangement of conductive needles 1, both extending along the first direction. Since the detection device of this application determines whether two adjacent strip conductive electrodes 6 are energized by the on / off state of the indicator lights 2, only one contact point is needed between the conductive needles 1 and the strip conductive electrodes 6 to ensure electrical conduction. In contrast, the prior art method for testing resistance values ​​requires two contact points for each strip conductive electrode 6, i.e., two rows of conductive needles, because it needs to test the resistance value between different parts of the same strip conductive electrode 6. Compared to this structure, the detection device of this application has a simpler structure and is more convenient for detection.

[0050] In optional embodiments, such as Figures 2-5As shown, the support component 3 includes: a base 301; a guide rail 302, which is protruding and fixedly disposed on the base 301; and a platform 303, which is slidably disposed on the guide rail 302 and is used to support the conductive substrate 5; wherein the extension direction of the guide rail 302 is perpendicular to the first direction and parallel to the strip conductive electrode 6 of the conductive substrate 5 placed on the platform 303. In this structure, the plate-shaped base 301 serves as the supporting component of the entire detection device and integrates the entire detection device. All other components of the detection device are mounted on the base 301. The platform 303 is a plate-shaped platform parallel to the base 301, and its function is to support the conductive substrate 5. When the conductive substrate 5 needs to be detected, it is first placed on the platform 303. Since the base 301 is provided with a guide rail 302, and the platform 303 is slidably mounted on the guide rail 302 (specifically, a slider 304 is fixedly connected to the bottom surface of the platform 303, and the slider 304 is slidably connected to the guide rail 302), the conductive substrate 5 on the platform 303 can be translated by sliding the platform 303 on the guide rail 302. This movement allows the conductive substrate 5 to move closer to the conductive needle 1 (i.e., from a position that is vertically misaligned with the conductive needle 1 to a position that is vertically aligned with the conductive needle 1), so as to ensure that the conductive needle 1 can make conductive contact with the strip conductive electrode 6 on the conductive substrate 5 during subsequent operations. To improve ease of operation, the guide rail 302 is positioned on the base 301 in a direction perpendicular to the first direction. When the conductive substrate 5 is placed on the stage 303, the strip conductive electrodes 6 on the conductive substrate 5 are parallel to the guide rail 302. This allows the conductive substrate 5 to move along the length of the strip conductive electrodes 6 and approach the conductive needles 1. Since the conductive needles 1 are arranged along the first direction, and the direction of movement of the conductive substrate 5 (i.e., the length direction of the strip conductive electrodes 6) is perpendicular to the first direction, the arrangement direction of the conductive needles 1 is the same as the arrangement direction of all the strip conductive electrodes 6. Thus, after the conductive substrate 5 approaches the conductive needles 1, the conductive needles 1 can make one-to-one conductive contact with the strip conductive substrate. Furthermore, the extension direction of the guide rail 302 or the length direction of the strip conductive electrodes 6 (i.e., the placement direction of the conductive substrate 5 on the stage 303) can also have an angle other than 90° and 180° with the first direction. Thus, by moving the stage 303 on the guide rail 302, it is also possible for the conductive needles 1 to make one-to-one conductive contact with the strip conductive electrodes 6.

[0051] In another alternative embodiment, the support component 3 may include: a base 301; and a turntable (not shown), rotatably mounted on the base 301, for supporting the conductive substrate 5. In this structure, the turntable replaces the guide rail 302 and the platform 303, and the conductive substrate 5 is placed on the turntable. This turntable can be understood as a platform that can rotate around its own axis, and the turntable is located below the conductive needle 1. Alternatively, the turntable may not be located below the conductive needle 1, but the conductive needle 1 may be moved above the turntable by translating the mounting component 4 on the base 301. In this way, after the conductive substrate 5 is placed on the turntable, the one-to-one alignment and conductive contact between all the strip conductive electrodes 6 and all the conductive needles 1 can be achieved by rotating the conductive substrate 5.

[0052] Based on the above structure, such as Figures 2-5As shown, the mounting assembly 4 includes: a first column 401 and a second column 402, which are mounted on the base 301 and located on both sides of the guide rail 302 or the turntable, respectively; a crossbeam 403, with both ends slidably connected to the first column 401 and the second column 402, so as to be able to move up and down above the conductive substrate 5 placed on the platform 303; wherein, all the conductive pins 1 are mounted on the crossbeam 403 and extend downward from the bottom surface of the crossbeam 403; all the indicator lights 2 are mounted on the top surface and / or side surface of the crossbeam 403; the first direction of extension is the length direction of the crossbeam 403. In this structure, the first column 401, the second column 402, and the crossbeam 403 constitute a support spanning above the guide rail 302 or the turntable. The first column 401 and the second column 402 are fixedly mounted on the base 301, while the crossbeam 403 can slide up and down on the first column 401 and the second column 402. That is, the crossbeam 403 can rise and fall on the first column 401 and the second column 402. The conductive needle 1 and the indicator light 2 are both mounted on the crossbeam 403. Specifically, the conductive needle 1, which is arranged in a row along the length of the crossbeam 403, extends downward from the bottom surface of the crossbeam 403 so that the conductive needle 1 can make conductive contact with the conductive substrate 5 located on the guide rail 302 or the turntable below as the crossbeam 403 descends. The indicator light 2 is mounted on the top surface and / or side surface of the crossbeam 403 for easy observation by the tester. Furthermore, the distance between the first column 401 and the second column 402 must be greater than the width of the conductive base 5. During the testing operation, the stage 303 is first moved to one end of the guide rail 302 (i.e., the edge of the base 301) so that the stage 303 is misaligned with the first column 401 and the second column 402. This also makes it easier for the testing personnel to place the conductive base 5 on the stage 303. Then, the crossbeam 403 is raised on the first column 401 and the second column 402 to ensure that the lower end of the conductive needle 1 is higher than the conductive base 5 on the stage 303. Then, the stage 303 is moved on the guide rail 302 so that the conductive base 5 is moved between the first column 401 and the second column 402, and the strip conductive electrode 6 is located below the conductive needle 1. At this time, all the strip conductive electrodes 6 and all the conductive needles 1 are aligned vertically. Then, the crossbeam 403 is lowered until the lower end of the conductive needle 1 makes conductive contact with the strip conductive electrode 6. After that, the testing personnel can observe the on / off status of the indicator light 2. When a turntable is installed on the base 301 and the turntable is located below the crossbeam 403, the crossbeam 403 is first moved until the lower end of the conductive needle 1 is higher than the conductive base 5 placed on the turntable. Then the conductive base 5 is placed on the turntable. The turntable is then rotated so that all the strip conductive electrodes 6 on the conductive base 5 are aligned vertically with all the conductive needles 1. Then the crossbeam 403 is lowered until the lower end of the conductive needle 1 makes conductive contact with the strip conductive electrode 6. After that, the inspector can observe the on / off status of the indicator light 2.

[0053] In the above structure, there are several options for the sliding connection between the crossbeam 403 and the first column 401 and the second column 402. For example, vertical guide rails 302 can be provided on the first column 401 and the second column 402, and the two ends of the crossbeam 403 can be slidably connected to the vertical guide rails 302 on the first column 401 and the second column 402, respectively. Alternatively, vertical grooves can be opened on the first column 401 and the second column 402, and both ends of the crossbeam 403 can be provided with protrusions that can extend into the grooves and slide in the grooves.

[0054] Furthermore, in optional embodiments, the detection device provided in this application may include: a first drive motor (not shown in the figure), mounted on the base 301, for driving the stage 303 to move on the guide rail 302 or for driving the turntable to rotate; and / or, a second drive motor (not shown in the figure), mounted on the first column 401 or the second column 402, for driving the crossbeam 403 to rise and fall. In this structure, by setting the first drive motor to drive the stage 303 to move automatically or the turntable to rotate automatically, and / or by setting the second drive motor to drive the crossbeam 403 to rise and fall automatically, the automation and intelligence of the detection device can be improved, and the smoothness of movement, rotation, and rising and falling can also be improved. At the same time, the alignment accuracy can also be improved, resulting in better detection effect and higher detection efficiency. In addition, the movement of the stage 303, the rotation of the turntable, and the rising and falling of the crossbeam 403 can also be achieved by manual operation.

[0055] Furthermore, a limiting baffle (not shown in the figure) can be set on the stage 303 or the turntable. After the conductive substrate 5 is placed on the stage 303 or the turntable, one edge of the conductive substrate 5 can be made to fit against the limiting baffle, thereby limiting the relative position of the conductive substrate 5 with the stage 303 or the turntable. This ensures that all the strip conductive electrodes 6 of the conductive substrate 5 located on it are precisely aligned with all the conductive needles 1 after the stage 303 moves or the turntable rotates, avoiding the situation where the strip conductive electrodes 6 cannot be aligned with the conductive needles 1 after the stage 303 moves or the turntable rotates. This improves the working performance of the detection device and makes it more effective.

[0056] In this application, LED beads were selected as the indicator light 2. The reason for selecting LED beads as the indicator light 2 is that LEDs are more sensitive to current and voltage. Even if the conductivity between two adjacent strip conductive electrodes 6 is weak, the indicator light 2 can still light up, thus enabling more sensitive and accurate detection of the power supply status. In addition, LED beads have high brightness and are more conspicuous when they are lit, making it easier for inspectors to observe the indicator light 2 lighting up. At the same time, LED beads are small in size, making it easy to install and arrange on the crossbeam 403.

[0057] In an optional embodiment, all indicator lights 2 are electrically connected to the positive or negative terminal of the same power source (not shown in the figure). That is, half of the indicator lights 2 are electrically connected to the positive terminal of the same power source, and the other half are electrically connected to the negative terminal. As mentioned above, indicator lights 2 connected to different terminals are alternately arranged. This power source can be a battery or a power grid. Using the same power source to power all indicator lights 2 simplifies the structure of the detection device. In specific connections, all indicator lights 2 connected to the positive terminal and the conductive needle 1 form multiple parallel circuits (i.e., the aforementioned series conductive structures, where multiple series conductive structures are in parallel). Similarly, all indicator lights 2 connected to the negative terminal and the conductive needle 1 form multiple parallel circuits. Any series conductive structure connected to the positive terminal and any series conductive structure connected to the negative terminal can form a conductive loop through the conduction of two strip conductive electrodes 6. Alternatively, all indicator lights 2 can also be electrically connected to the positive or negative terminals of multiple power sources respectively.
