Description

Technical Field

[0001] This invention relates to the field of UV irradiation equipment technology, specifically to a contactless photovoltaic cell UV reliability testing device and its testing method. Background Technology

[0002] When performing reliability analysis on photovoltaic cells under UV irradiation, existing equipment requires workers to repeatedly take samples manually, subject the samples to prolonged UV irradiation, conduct contact tests on the samples, and then collect and analyze the results.

[0003] In existing equipment, when photovoltaic cells are subjected to UV irradiation, workers repeatedly and manually handle samples for sampling and testing. This contact-based sampling and testing process can easily lead to inaccurate test data. Poor handling of the UV light environment during irradiation may also pose safety hazards. Furthermore, the contact involved in manually handling irradiated samples to the testing equipment can easily affect the test results. Summary of the Invention

[0004] To overcome the potential safety hazards caused by improper handling of the UV light environment during irradiation, and the problem that contact during manual handling of irradiated samples to the testing equipment can easily affect the test results, this invention provides a contactless UV reliability testing device for photovoltaic cells, including a testing chamber, and further comprising:

[0031] Preferably, the limiting component further includes:

[0032] The channel opened inside the first pad and the spring installed inside the channel;

[0033] A movable rod is disposed outside the spring and is slidably connected to the inside of the channel;

[0034] A guardrail is installed at the end of the moving rod away from the first pad, and a support rod is installed above the guardrail to limit the position of the sample.

[0035] This invention provides a contactless method for UV reliability testing of photovoltaic cells, comprising the following steps:

[0036] S1. Start the second external fan to send the gas into the detection box;

[0037] S2. Switch the mode of the first external fan to stably confine the sample in the limiting component;

[0038] S3. Start the first push rod. The first push rod drives the sample to move inside the detection chamber to complete the detection work and obtain the data before irradiation.

[0039] S4. The second push rod moves the sample into the light box, switches the limit component status, uses the light box for UV light treatment, adjusts the gas circulation by speed change, and the gas carries ozone and exhaust gas into the treatment equipment.

[0040] S5. Switch the state of the limiting component. The second push rod transports the sample back to the detection box. Repeat the detection process to obtain post-irradiation data for comparison of performance changes.

[0041] This invention provides a contactless photovoltaic cell UV reliability testing device and method. It has the following beneficial effects:

[0042] 1. This contactless UV reliability testing equipment and method for photovoltaic cells utilizes a testing box, detector, illumination box, and lamp box to perform separate tests on samples before and after irradiation, thereby testing the performance changes of the samples before and after irradiation. Existing UV irradiation equipment requires workers to manually handle the irradiated samples and transfer them to the testing equipment after UV irradiation, a process that can easily affect the test results. Therefore, this method establishes a connected testing box and illumination box to facilitate sample testing before and after irradiation, and solves the aforementioned problem by implementing contactless placement and testing. Furthermore, by testing the samples before and after UV irradiation and adjusting the light intensity based on the data, the irradiation time of the samples can be shortened.

[0043] 2. This contactless photovoltaic cell UV reliability testing equipment and method comprises an air inlet duct, an air outlet, a testing box, a light box, a first exhaust duct, and a second exhaust duct. A second external fan delivers treated gas through the testing box into the light box. The gas in the light box, along with ozone generated by UV irradiation, is discharged into the processing equipment through the first and second exhaust ducts connected to the light box. Since the light box has heat dissipation vents on its side and an exhaust vent on its top, both vents and exhaust vents are located within the outer casing. The gas within the casing is discharged into the processing equipment through the second exhaust duct, preventing safety hazards caused by inadequate ozone treatment in the UV environment.

[0044] 3. This contactless photovoltaic cell UV reliability testing equipment and method utilizes a transfer mechanism. A first push rod adjusts the positions of the first sliding frame, second sliding frame, tray, limiting components, and sample within the testing chamber to control the sample's position within the testing areas of multiple detectors. A second push rod adjusts the movement of the second sliding frame, tray, limiting components, and sample within the testing chamber and light box to control the sample's position in the irradiation or testing location. Traditional equipment uses rails to transport the tray and sample; however, the high temperature in the UV irradiation area can easily damage the rails and other structures over time. Therefore, the second push rod, second sliding frame, tray, and limiting components address these issues.

[0045] 4. The contactless photovoltaic cell UV reliability testing equipment and its testing method, by setting up an air supply component, and forming an air path through an air inlet pipe, a first chamber, a connecting box, a moving pipe and a connecting membrane, sends the treated gas into the light box, which can both remove the heat generated by the UV light source and promote the gas circulation inside the light box.

[0046] 5. This contactless photovoltaic cell UV reliability testing equipment and method utilizes a limiting component. Negative pressure generated by the suction port at the top of the vertical tube adsorbs and fixes the sample, achieving contactless flexible limiting and avoiding scratches or indentations on the sample surface caused by traditional mechanical clamping. Simultaneously, this component shares the same air source with the air supply component. By switching between suction and air supply modes, negative pressure can be used to lock the sample in place during testing to ensure stable positioning. During UV irradiation, switching to air supply mode automatically moves the plate away from the sample, preventing light obstruction and ensuring uniform irradiation. Attached Figure Description

Detailed Implementation

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0058] like Figures 1-9 As shown, the present invention provides a technical solution: a contactless photovoltaic cell UV reliability testing device, which is described below.

[0059] Including detection box 1, it also includes:

[0060] The detector 7 is set inside the detection chamber 1. There are multiple detectors 7, which perform various tests on the sample, such as non-contact current and voltage (IV) detection, photoluminescence (PL) detection, Raman spectroscopy detection, and Fourier transform infrared spectroscopy detection, to test the performance changes of the sample before and after irradiation.

[0061] The light box 2 and the lamp box 3 are set outside the detection box 1. The lamp box 3 is equipped with a UV light source, and the top of the lamp box 3 is provided with an exhaust vent. The bottom of the lamp box 3 is connected to the light box 2.

[0062] The base frame 8 is installed inside the light box 2. The base frame 8 can be configured as a water-cooled structure. The side of the light box 2 has heat dissipation vents.

[0063] The transfer mechanism 9 is located outside the base frame 8. The transfer mechanism 9 includes a second push rod 905 located above the base frame 8, a second sliding frame 906 connected to the telescopic end of the second push rod 905, and a limiting component 908 located above the second sliding frame 906. The second push rod 905 is used to drive the limiting component 908 to move in the detection box 1 and the light box 2. The second push rod 905 is set as an electric push rod. The second sliding frame 906 has a second chamber inside. The transfer mechanism 9 can be set as a water-cooled structure.

[0064] The first exhaust duct 4 is installed outside the light box 2 and is connected to the processing equipment.

[0065] The air inlet pipe 5 is installed outside the test box 1 and the air inlet pipe 6 is installed inside the test box 1. The air inlet pipe 6 is connected to the first external fan and the air inlet pipe 5 is connected to the second external fan. During the use of the equipment, the second external fan is always in the start mode.

[0066] An air inlet 10 is located on the top of the test box 1. The air inlet 10 is connected to the air inlet pipe 5 through the first external pipe, and then connected to the first external fan through the air inlet pipe 5.

[0067] The outer casing 11 is located outside the light box 2, and the second exhaust duct 12 is installed inside the outer casing 11. The first exhaust duct 4 passes through the outer casing 11, and the second exhaust duct 12 is connected to the first exhaust duct 4 through a second external pipe, and then connected to the processing equipment through the first exhaust duct 4.

[0068] Before using the equipment, the sample to be irradiated is automatically positioned and placed in the limiting component 908. The inlet pipe 6 is connected to the first external fan, and the inlet pipe 5 is connected to the second external fan. The second external fan is activated, and the treated gas enters the detection chamber 1 through the inlet pipe 5 and the inlet 10. This carries the ozone and gas from the light chamber 2 through the first exhaust pipe 4, the heat dissipation vent, the exhaust vent, and the second exhaust pipe 12 into the treatment equipment, thus completing the gas delivery and replacement. After the worker places the sample in the limiting component 908, the detector 7 detects the sample before irradiation. Then, the transfer mechanism 9 carries the sample into the light chamber 2, where it is irradiated using the UV light source in the lamp box 3. The transfer mechanism 9 then carries the sample back to the detection chamber 1, where the detector 7 detects the irradiated sample. Automatic positioning, suction, and transfer of the sample to be irradiated can be achieved using a robotic arm.

[0069] By setting up a detection chamber 1, a detector 7, an illumination chamber 2, and a lamp box 3, samples are tested separately before and after irradiation, thereby measuring the changes in sample performance. Existing UV irradiation equipment requires workers to manually handle the irradiated samples and transfer them to the detection equipment after UV irradiation, a process that can easily affect the test results. Therefore, a connected detection chamber 1 and illumination chamber 2 are provided to facilitate sample testing before and after irradiation, thus solving the aforementioned problem.

[0070] By configuring an air inlet duct 5, an air inlet 10, a detection box 1, a light box 2, a first exhaust duct 4, and a second exhaust duct 12, a second external fan sends the treated gas through the detection box 1 into the light box 2. The gas in the light box 2, along with the ozone generated by UV irradiation, is discharged into the processing equipment through the first exhaust duct 4 and the second exhaust duct 12, both connected to the light box 2. Since the light box 2 has a heat dissipation vent on its side and the light box 3 has an exhaust vent on its top, both vents are located within the outer casing 11. The gas within the outer casing 11 is discharged into the processing equipment through the second exhaust duct 12. Ozone can react with the silicon wafer surface, producing undesirable reactants, leading to inaccurate test results and generating significant heat. Therefore, by configuring the above structure, the ozone and waste gas are discharged from the equipment to solve these problems.

[0071] Transfer agency 9 also includes:

[0072] A first connecting pipe 901 and an air supply assembly 902 connected to the first connecting pipe 901 are disposed on the outside of the base frame 8.

[0073] The first push rod 903 and the first sliding frame 904 connected to the telescopic end of the first push rod 903 are installed inside the detection box 1. The first sliding frame 904 is slidably connected to the inside of the base frame 8. The second push rod 905 is installed inside the first sliding frame 904. The first push rod 903 is set as an electric push rod.

[0074] The tray 907, which is mounted on the second sliding frame 906, can be water-cooled to further control the temperature of the silicon wafer.

[0075] A groove 909 is formed inside the tray 907, and a limiting component 908 is disposed inside the groove 909.

[0076] The process of using the transfer mechanism 9 to limit the position of the sample:

[0077] Before using the equipment, the sample is placed in the limiting component 908 in the tray 907 by automatic positioning and aspiration.

[0078] The process of adjusting the sample position using the transfer mechanism 9:

[0079] The first push rod 903 is activated to multiple strokes, driving the first sliding frame 904, the limiting component 908, and the sample to move inside the detection chamber 1. This controls the position of the sample to correspond with the multiple detectors 7 above, which then detect the sample. The first push rod 903 is then adjusted to its initial state, and the second push rod 905 is activated. The second push rod 905 drives the second sliding frame 906, the limiting component 908, and the sample into the light box 2. The sample is then irradiated by a UV light source. After irradiation, the second push rod 905 is adjusted to its initial state, causing the second sliding frame 906 to return to the detection chamber 1. The detection process is then repeated to test the irradiated sample.

[0080] By setting up a transfer mechanism 9, the first push rod 903 adjusts the positions of the first sliding frame 904, the second sliding frame 906, the tray 907, the limiting component 908, and the sample in the detection box 1 to control the sample to be in the detection area of ​​multiple detectors 7. The second push rod 905 adjusts the movement of the second sliding frame 906, the tray 907, the limiting component 908, and the sample in the detection box 1 and the light box 2 to control the sample to be in the irradiation position or the detection position. In traditional equipment, a track is used to transport the tray 907 and the sample. However, the temperature in the UV irradiation area is too high, and long-term use can easily lead to damage to the track and other structures. Therefore, the second push rod 905, the second sliding frame 906, the tray 907, and the limiting component 908 are used to solve the above problems.

[0081] Air supply assembly 902 includes:

[0082] A first chamber 9022 is located inside the base frame 8 and is connected to the air intake pipe 6;

[0083] Connection box 9021 installed outside the first connecting pipe 901;

[0084] The flexible hose 9023 is located above the base frame 8, with one end of the flexible hose 9023 away from the base frame 8 located in the second chamber within the second sliding frame 906;

[0085] The telescopic rod 9024 is installed inside the connecting box 9021 and has an automatic retraction function.

[0086] The movable tube 9025 installed on the telescopic end of the telescopic rod 9024 and the gasket 9026 set outside the movable tube 9025 are closed at the end of the movable tube 9025 away from the connecting box 9021.

[0087] A connecting membrane 9027 is disposed inside the connecting box 9021 and is connected to the moving tube 9025.

[0088] During UV irradiation, the process of using the air supply component 902 to supply air to the inside of the light box 2 is as follows:

[0089] When the first external fan is started, gas enters the first chamber 9022 through the air inlet pipe 6. Then, the gas enters the connecting box 9021 through the first connecting pipe 901. Driven by the gas, the moving pipe 9025 moves upward, the telescopic rod 9024 is stretched, and the gas moves outward through the connecting membrane 9027, which blows air into the interior of the light box 2, promotes the cooling of the gas inside the light box 2, and accelerates the gas circulation inside the light box 2.

[0090] Limiting component 908 includes:

[0091] The vertical tube 9081 installed at the bottom of the tray 907 and the second connecting tube 9082 connected to the vertical tube 9081, the side of the second connecting tube 9082 away from the vertical tube 9081 extends into the second chamber of the second sliding frame 906, the upper and lower ends of the vertical tube 9081 are closed, and a suction port is opened at the top of the vertical tube 9081 for negative pressure suction of the sample.

[0092] A first pad 9083 and a second pad 9088 connected to the first pad 9083 are disposed outside the vertical tube 9081.

[0093] A channel 9084 is formed inside the first pad 9083 and a spring 9085 is disposed inside the channel 9084. The spring 9085 is installed in the channel 9084 through a connector.

[0094] A movable rod 9086 is disposed outside the spring 9085, and the movable rod 9086 is slidably connected to the inside of the channel 9084;

[0095] The guardrail 9087 is installed on the end of the movable rod 9086 away from the first pad 9083.

[0096] The process of using the limiting component 908 to limit the sample in the initial state:

[0097] When the first external fan is activated to the air supply mode, gas enters the first chamber 9022 through the inlet pipe 6, then enters the hose 9023 through the first chamber 9022, then enters the second chamber through the hose 9023, and finally enters the two vertical pipes 9081 through the second chamber and the second connecting pipe 9082. The gas entering the two vertical pipes 9081 enters the channel 9084 in the first pad 9083, and pushes the moving rod 9086 and the guardrail 9087 to move, at which time the spring 9085 is stretched.

[0098] The sample is placed on the first pad 9083 and the second pad 9088 by automatic positioning and suction. Then, the first external fan is adjusted to the exhaust mode. Under the action of gas suction, the moving rod 9086 returns to the channel 9084, the spring 9085 is squeezed, and the guard plate 9087 limits the sample.

[0099] The process of releasing the sample during UV irradiation using the limiting component 908:

[0100] During irradiation, start the first external fan in supply mode and keep the guardrail 9087 away from the sample to avoid obstructing the irradiation process. After irradiation, switch the first external fan to exhaust mode and fix the sample in place for subsequent testing.

[0101] By setting up the air supply component 902, the air passage is formed by the air inlet pipe 6, the first chamber 9022, the connecting box 9021, the moving pipe 9025 and the connecting membrane 9027, and the treated gas is sent into the light box 2. This can not only remove the heat generated by the UV light source, but also promote the gas circulation inside the light box 2.

[0102] By setting up a limiting component 908, negative pressure is generated by the suction port at the top of the vertical tube 9081 to adsorb and fix the sample, achieving non-contact flexible limiting and avoiding scratches or indentations on the sample surface caused by traditional mechanical clamping. At the same time, this component shares the same air source with the air supply component 902. By switching between suction and air supply modes, negative pressure can be used to lock the sample with the baffle 9087 during detection to ensure stable position, while switching to air supply mode during UV irradiation will automatically move the baffle 9087 away from the sample to avoid blocking light and ensure uniform irradiation.

[0103] Working principle: When the second external fan is started, the treated gas enters the detection box 1 through the air inlet pipe 5 and the air inlet 10, which drives the ozone and the gas in the light box 2 to enter the treatment equipment through the first exhaust pipe 4, the heat dissipation port, the exhaust port and the second exhaust pipe 12, thereby completing the gas transportation and replacement work.

[0104] When the first external fan is activated to the air supply mode, gas enters the first chamber 9022 through the inlet pipe 6, then enters the hose 9023 through the first chamber 9022, then enters the second chamber through the hose 9023, and finally enters the two vertical pipes 9081 through the second chamber and the second connecting pipe 9082. The gas entering the two vertical pipes 9081 enters the channel 9084 in the first pad 9083, and pushes the moving rod 9086 and the guardrail 9087 to move, at which time the spring 9085 is stretched.

[0105] The sample is placed on the first pad 9083 and the second pad 9088 by automatic positioning and suction. Then, the first external fan is adjusted to the exhaust mode. Under the action of gas suction, the moving rod 9086 returns to the channel 9084, the spring 9085 is squeezed, and the guard plate 9087 limits the sample.

[0106] The first push rod 903 is activated to multiple strokes, driving the first sliding frame 904, the limiting component 908, and the sample to move inside the detection chamber 1. This controls the position of the sample to correspond with the positions of the multiple detectors 7 above, allowing the detectors 7 to detect the sample. Then, the first push rod 903 is adjusted to its initial state, and the second push rod 905 is activated. The second push rod 905 drives the second sliding frame 906, the limiting component 908, and the sample into the light chamber 2.

[0107] Before irradiation, turn on the first external fan to the air supply mode, and keep the guardrail 9087 away from the sample to avoid affecting the sample irradiation work due to the guardrail 9087 blocking the sample.

[0108] The sample is then irradiated by a UV light source. The first external fan is activated, and gas enters the first chamber 9022 through the inlet pipe 6. Subsequently, the gas enters the connecting box 9021 through the first connecting pipe 901. Driven by the gas, the moving pipe 9025 moves upward, stretching the telescopic rod 9024. The gas then moves outward through the connecting membrane 9027, supplying air to the interior of the light box 2, promoting cooling of the gas inside and accelerating gas circulation. After irradiation, the first external fan is switched to exhaust mode to fix the sample in place for subsequent testing. The second push rod 905 is adjusted to its initial state, causing the second sliding frame 906 to return to the testing box 1. The above testing process is repeated to test the irradiated sample. This method is applicable not only to testing photovoltaic cells but also to testing photovoltaic modules.

[0109] This invention provides a contactless method for UV reliability testing of photovoltaic cells, comprising the following steps:

[0110] S1. Start the second external fan to send the gas into the detection box 1;

[0111] S2. Switch the mode of the first external fan to stably confine the sample in the limiting component 908;

[0112] S3. Start the first push rod 903. The first push rod 903 drives the sample to move in the detection chamber 1 to complete the detection work and obtain the data before irradiation.

[0113] S4. The second push rod 905 transfers the sample to the light box 2, switches the state of the limit component 908, uses the light box 3 for UV light treatment, adjusts the gas circulation by speed change, and the gas carries ozone and exhaust gas into the treatment equipment.

[0114] S5. Switch the state of the limit component 908. The second push rod 905 transports the sample back to the detection box 1. Repeat the detection process to obtain post-irradiation data for comparison of performance changes.
