Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell testing, and in particular to a partition testing method for thin-film photovoltaic cells. Background Art

[0002] Currently, the performance evaluation and testing of thin-film batteries are generally performed using a probe row system. Technicians press a row of special probes onto the back plates of the first and last batteries in the thin-film battery pack to ensure that they can stably and evenly contact the battery surface, thereby effectively reducing the contact resistance and improving the accuracy of the test.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0027] The thin-film photovoltaic cell partitioning test method of the present application can perform a systematic and independent performance evaluation on the thin-film photovoltaic cells that have been partitioned. The solar panel is divided into multiple independent and functionally complete areas. Through the test method of the present application, the performance of each area can be accurately tested separately, thereby greatly improving the accuracy and reliability of the test results. Figure 1 As shown, the solar panel is divided into three independent areas, namely the first area 001, the second area 002 and the third area 003. Such a partition design facilitates operation and management during the test process.

[0028] When performing specific test operations, the test method of the present application can perform independent performance tests on the preset scribe positions in each area to ensure the authenticity and pertinence of the data. This method of distinguishing photovoltaic panels and testing them one by one avoids test errors caused by performance differences between regions, and provides more scientific and rigorous data support for the performance evaluation of thin-film photovoltaic cells.

[0029] The left and right directions described in this application are Figure 1 The left and right directions shown in the figure, and the up and down directions described in this application are Figure 2 The up-down direction shown in the figure, the front-back direction described in the present application is Figure 1 Up and down directions shown.

[0030] like Figure 1 As shown, the thin-film photovoltaic cell partition testing method according to an embodiment of the present application uses a device including: a suspension rod 100 , a lifting cylinder 200 , a connecting plate 600 , a probe row 300 and a moving part 400 .

[0031] The lifting cylinder 200 is fixedly arranged at the top of the suspension rod 100, and a connecting plate 600 is arranged at the bottom of the suspension rod 100. The lifting cylinder 200 is connected to the connecting plate 600, and can drive the connecting plate 600 to move up and down; the probe row 300 is fixedly arranged at the bottom of the connecting plate 600; there are multiple connecting plates 600 along the extension direction of the suspension rod 100, and the number of connecting plates 600, probe rows 300 and lifting cylinder 200 is the same, and multiple probe rows 300 are arranged in parallel; the suspension rod 100 is suitable for being arranged above the photovoltaic cell 500, and the suspension rod 100 can be moved to the top of the photovoltaic cell 500; the moving part 400 is connected to the suspension rod 100, and can drive the suspension rod 100 to move left and right.

[0032] During the test, a thin-film photovoltaic cell partitioning test method is performed based on the above-mentioned device, including: placing the photovoltaic cell 500 on the table, and moving the suspension rod 100 to the top of the photovoltaic cell 500; the lifting cylinder 200 drives the connecting plate 600 to move up and down, and the connecting plate 600 drives the probe row 300 to move up and down; when the connecting plate 600 is at the lowest point, the probe row 300 is set in contact with the photovoltaic cell 500.

[0033] Specifically, the number of probe rows 300 is the same as the number of partitions set for the thin-film photovoltaic cell 500 to be tested. If the photovoltaic cell 500 is divided into three areas along the front-to-back direction, three probe rows 300 are installed on the suspension rod 100, and the length of each probe row 300 in the front-to-back direction is consistent with the length of the corresponding partition in the front-to-back direction. If the three partitions are of the same size, the lengths of the three probe rows 300 installed on the suspension rod 100 are also the same. If the lengths of the three partitions of the photovoltaic cell 500 in the front-to-back direction are different, the length of each probe row 300 is also different, and the length of the probe row 300 is the same as the length of the partition of the corresponding photovoltaic cell 500. The length of each probe row 300 can be prepared for production in advance according to the actual partition situation.

[0034] In this embodiment, there is a preset gap between two adjacent probe rows 300, so that different probe rows can be raised and lowered independently. When the photovoltaic cells 500 in the first area 001 need to be tested, the probe rows 300 corresponding to the second area 002 and the third area 003 remain stationary, and the test purpose is achieved only by controlling the probe row 300 corresponding to the position of the first area 001. That is, when the battery in a certain area is to be tested, the probe row 300 in the corresponding area is pressed down, thereby achieving battery testing in different areas.

[0035] A plurality of probes are arranged along the front-to-back direction at the bottom of the connecting plate 600 to form a probe row 300. The frontmost and rearmost probes of the probe row 300 are respectively arranged flush with the front and rear ends of the connecting plate 600, and the distance between two adjacent probes in the front-to-back direction is less than the width of one probe. Since there is a preset gap between the probe rows 300, the gap between two probe rows 300 is less than the width of one probe, so that the area where two photovoltaic cells 500 intersect can also be tested.

[0036] like Figure 1 As shown, the photovoltaic cell 500 board is placed on a horizontal table, the setting height of the suspension rod 100 is higher than the setting height of the photovoltaic cell 500, and there is a preset distance between the suspension rod 100 and the photovoltaic cell 500, which can ensure that the suspension rod 100, the connecting plate 600 and the probe row 300 will not contact the photovoltaic cell 500 when moving left and right, so as to avoid scratching the photovoltaic cell 500 during the movement. The suspension rod 100 is a straight rod arranged in the front-to-back direction, which can move left and right in the horizontal direction above the photovoltaic cell 500. The length of the suspension rod 100 is greater than the length of the photovoltaic cell 500 board in the front-to-back direction, so as to ensure that the path of the suspension rod 100 can cover all positions of the photovoltaic cell 500 board in the front-to-back direction.

[0037] In this embodiment, the moving part 400 is a synchronous belt, and the moving parts 400 are arranged at both ends of the suspension rod 100 in the front-back direction. The moving part 400 is also arranged horizontally, and the moving part 400 is perpendicular to the suspension rod 100. The two ends of the suspension rod 100 are connected to the moving part 400 by bolts, so that the moving part 400 can drive the suspension rod 100 to move left and right. When the suspension rod 100 moves to the middle position of the moving part 400, the moving part 400 and the suspension rod 100 are in an "I"-shaped structure. This application does not limit the type of the moving part 400, as long as it can drive the suspension rod 100 to move left and right. In one possible implementation, the number of movable parts 400 is one, that is, when the hanger 100 moves to the middle position of the movable part 400, the movable part 400 and the hanger 100 are in a "T"-shaped structure, wherein the side of the hanger 100 that is not connected to the movable part 400 is used for sliding connection to the machine tooling. As long as the hanger 100 can be horizontally arranged and can move at a uniform speed under the action of the movable part 400, the hanger 100 can always be kept flush with the marking line of the photovoltaic cell 500.

[0038] like Figure 2As shown, further, the "I"-shaped structure composed of two movable parts 400 and one suspension rod 100 is a group of movable components, and the number of movable components can be set to multiple, and the multiple movable components are arranged along the left-right direction. The movable parts 400 on the same side of the front-back direction of the photovoltaic cell 500 are extended along the same left-right direction, and the multiple suspension rods 100 are arranged in parallel, and the moving range of the multiple suspension rods 100 on the movable part 400 can completely cover the setting range of the photovoltaic cell 500.

[0039] In one achievable manner, a connecting plate 600 is provided at the bottom of the suspension rod 100. The connecting plate 600 is made of metal, preferably copper plate, which is a long strip-shaped plate-like structure. The width of the copper plate is the same as or smaller than the width of the suspension rod 100. Multiple connecting plates 600 are provided along the front-to-back direction of the suspension rod 100, and can be independently controlled to move up and down by the lifting cylinder 200. There is a gap between each connecting plate 600. The gap distance between each connecting plate 600 can be flexibly adjusted according to the area that the photovoltaic cell 500 needs to measure. The smaller the distance between the connecting plates, the wider the coverage of the measurement data. The connection between the connecting plate 600 and the suspension rod 100 and the connection between the connecting plate 600 and the lifting cylinder 200 are all detachable.

[0040] The lifting cylinder 200 is arranged at the top of the suspension rod 100, and the lifting cylinder 200 is a cylinder. The lifting cylinder 200 is arranged in the middle position of the connecting plate 600. When the lifting cylinder 200 controls the connecting plate 600 up and down, the connecting plate 600 always remains horizontal. A probe row 300 is arranged at the bottom of the connecting plate 600. The probe row 300 is arranged along the length direction of the suspension rod 100, that is, a plurality of probe rows 300 are arranged along the front-to-back direction. The probe row 300 is composed of a plurality of probe rows 300 columns, and the plurality of probes are evenly arranged along the front-to-back direction to ensure that the positive and negative needle angles of each probe are respectively arranged at the two ends of the line of the photovoltaic cell 500 in the area to be tested, and the two pins of each probe are at an equal distance from the line of the photometric cell 500. The number of probes provided in each probe row 300 can be flexibly set according to measurement needs, and the protruding height of each probe at the bottom of the connecting plate 600 is exactly the same, so that when measuring, when the connecting plate 600 drives the probe row 300 to move downward to the photovoltaic cell 500 board, all probes can abut against the photovoltaic cell 500 board at the same time, thereby accurately measuring the performance of the photovoltaic cell 500.

[0041] The testing method of the prior art can only test multiple regions at the same time and obtain the performance of multiple region batteries connected in parallel. The method of testing multiple regions at the same time cannot meet the needs of zoning tests for batteries, and thus cannot understand the uniformity of the electrical performance of the thin-film photovoltaic cell 500. The present application separates the test probe row 300 so that the displacement can be set independently to achieve the regional independent testing function of the thin-film photovoltaic cell 500.

[0042] When the photovoltaic cell 500 is divided into multiple parts, the traditional single-row probes cannot be used to test the divided cells individually. The probes can only be lowered at the same time to measure the entire cell. It is impossible to know the performance of the cells in each area, and it is impossible to know the performance uniformity of the entire cell, including but not limited to the performance information of multiple partitions in the front and rear directions of the photovoltaic cell 500 and the performance information of cells in different horizontal sections within a cell area.

[0043] The probe row 300 is divided into a plurality of independently controllable units corresponding to the partitions of the battery. Each small probe row 300 is equipped with an independent cylinder, and each probe row 300 is independently controlled. When the battery in a certain area is to be tested, the probe row 300 in the corresponding area is pressed down to achieve battery testing in different areas. At the same time, the lateral movement of the probe row 300 in the left and right directions is controlled by the moving part 400, so as to achieve the testing of batteries in a specific lateral area. The device of the present application can simultaneously control the left and right movement and the up and down movement of the probe row 300, and the precise measurement of the front and back can also be achieved by the independent control of the probe row 300.

[0044] In one achievable manner, the lifting cylinder 200 drives the corresponding connecting plate 600 to move up and down, and also includes: multiple lifting cylinders 200 respectively drive multiple connecting plates 600 to move up and down, and the lifting cylinders 200 and the connecting plates 600 are controlled one-to-one.

[0045] In one achievable manner, the suspension rod 100 is adapted to be arranged parallel to the scribe line of the photovoltaic cell 500; the probe row 300 is composed of at least two probes arranged in an array along the length direction of the suspension rod 100, and the positive and negative ends of the probe row 300 are adapted to be arranged across the scribe line.

[0046] In one achievable manner, the moving part 400 is a synchronous belt, and the moving part 400 is disposed on at least one end of the suspension rod 100 , and the suspension rod 100 can move left and right along the setting direction of the moving part 400 .

[0047] When the moving part 400 is provided at one end of the suspension rod 100, the other end of the suspension rod 100 can be connected to the device tooling through a pulley or other connection methods, as long as the suspension rod 100 can always remain parallel to the marking line during the action movement.

[0048] In one achievable manner, the moving portion 400 and the suspension rod 100 are vertically arranged.

[0049] In one practicable manner, the two ends of the suspension rod 100 are provided with the moving parts 400 , and the suspension rod 100 moves left and right along the setting direction of the moving parts 400 .

[0050] In one achievable manner, the suspension rod 100 and the two conveyor belts form a group of moving components, and two groups of moving components are disposed around the photovoltaic cell 500 , and the two groups of moving components have the same height in the horizontal direction.

[0051] In one practicable manner, the connecting plate 600 is a copper plate, and the copper plate is a long strip-shaped plate structure.

[0052] In one achievable manner, the lifting cylinder 200 drives the corresponding connecting plate 600 to move up and down, and also includes: multiple lifting cylinders 200 respectively drive multiple connecting plates 600 to move up and down, and the lifting cylinders 200 and the connecting plates 600 are controlled one-to-one.

[0053] It should be noted that although the present application is used as an example to introduce a thin-film photovoltaic cell partition test device and method as above, those skilled in the art will understand that the present application should not be limited thereto. In fact, the user can flexibly set various parameters according to personal preferences and / or actual application scenarios, as long as the design is reasonable.

[0054] In this way, a connecting plate is provided at the bottom of the suspension rod, and the connecting plate is lifted and lowered by a lifting part, and a probe is provided at the bottom of the connecting plate, so as to achieve the effect of the lifting part controlling the up and down movement of the probe, wherein a plurality of connecting plates are provided under the suspension rod, and a row of probes is respectively connected under each connecting plate, and each lifting part corresponds one-to-one to each connecting plate. According to a thin-film photovoltaic cell partitioning test device and method of the present application, separate partitioning tests can be performed on the partitioned photovoltaic cells, and the lifting and lowering of the probe row can be independently controlled, so as to obtain independent data of the battery performance of multiple regions and the overall performance uniformity information of the battery, so as to obtain more accurate measurement data and facilitate the analysis of the battery.

[0055] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
