Through detection, the photoelectric conversion efficiency of photovoltaic cells can be evaluated, and defects in materials, manufacturing processes, etc. of photovoltaic cells can be discovered. At the same time, through various environmental simulation tests and long-term aging tests, the reliability and expected service life of photovoltaic cells under different working conditions can be evaluated, which is very important for the long-term stable operation of photovoltaic systems.

[0003] Referring to a performance detection device for a photovoltaic cell disclosed in a patent application with a publication number of CN119182362B, this photovoltaic cell detection device controls the difference in the light source conversion performance of the photovoltaic cell at different temperatures, and further conforms to the outdoor use situation of the photovoltaic cell on the original basis, preventing detection solely relying on the angle change of visible light, thereby reducing the actual accuracy of the performance detection of the photovoltaic cell.

[0004] The above-mentioned photovoltaic cell detection device can provide different temperatures to simulate the performance of the photovoltaic cell.

Currently, the photovoltaic cell detection device cannot fully simulate the condition of dust accumulation on the surface of the photovoltaic cell, cannot simulate the outdoor environment, cannot know the actual situation of the photovoltaic cell under different thicknesses of dust accumulation, is not conducive to the evaluation of power generation efficiency, and the accurate prediction of the service life of the photovoltaic cell, and is not conducive to the improvement and upgrade of the photovoltaic cell.

[0085] Embodiment 2: Based on the switching member provided in Embodiment 1, this embodiment provides a further technical solution of the switching member.

[0086] As Figure 9 and Figure 10 shown, the switching member includes:

[0087] A first strip-shaped member 24 is slidably arranged in the conveying chamber 9 to block the first strip-shaped opening 10;

[0088] Two second strip-shaped members 25 are slidably arranged on both sides of the top inside the conveying chamber 9 to block the two second strip-shaped openings 11;

[0089] Two connecting members 26 are arranged between the first strip-shaped member 24 and the two second strip-shaped members 25. When the two second strip-shaped openings 11 are blocked, the first strip-shaped member 24 is opened, and conversely, when the first strip-shaped member 24 is closed, the two second strip-shaped openings 11 are opened;

[0090] Two reset springs 27 are arranged between the connecting piece 26 and the conveying chamber 9 to control the first strip-shaped piece 24 and the two second strip-shaped pieces 25;

[0091] The switching piece further includes:

[0092] Two control arms 28 are symmetrically arranged on both sides of the top of each connecting piece 26, and both control arms 28 slide through the conveying chamber 9;

[0093] Two traveling wheels 29 are rotatably installed on the two control arms 28;

[0094] Four inclined platforms 30 are distributed in a rectangle on the top of the conveying chamber 9, and each inclined platform 30 is in contact with the corresponding traveling wheel 29 to complete the control;

[0095] Two synchronous arms 31 are arranged between the two inclined platforms 30 to complete the synchronous control;

[0096] It further includes:

[0097] A spiral feeder 32 is arranged on the top of the batching chamber 12. An isolation plate 33 is installed at the bottom of the spiral feeder 32, and the isolation plate 33 is correspondingly slidably arranged in the batching chamber 12. A dust pipe is installed at the top of the spiral feeder 32, and the dust pipe communicates with an external dust source;

[0098] An air inlet pipe 34 is connected and arranged at the bottom on one side of the batching chamber 12. An air outlet pipe 35 is connected and installed at the bottom on the other side of the batching chamber 12. A first one-way valve for controlling the one-way feeding of gas into the conveying main pipe 22 is installed at the end of the air outlet pipe 35. The air outlet pipe 35 is communicated with the conveying main pipe 22 through a pipeline. A high-pressure blower 36 is installed below the batching chamber 12, and the high-pressure blower 36 is communicated with the air inlet pipe 34 through a pipeline;

[0099] It is worth noting that when simulating dust accumulation on the photovoltaic cell body 6: a conveying chamber 9 is provided, and the No. 2 linear module 8 is used to control the distance between the conveying chamber 9 and the photovoltaic cell body 6, and the No. 1 linear module 7 is used to control the movement of the conveying chamber 9, so as to complete the comprehensive dust coverage of the photovoltaic cell body 6 and avoid the simulated blind spot area. During subsequent accumulation, the dust in the batching chamber 12 is introduced through the conveying main pipe 22, and the dust gas is introduced into the conveying chamber 9 through multiple branch pipes 23. After that, the dust gas is ejected through the No. 1 strip opening 10 to the surface of the photovoltaic cell body 6 to simulate dust accumulation. Since the switching member can be linked with the control unit, the four inclined platforms 30 are pushed to move when the control unit is reciprocated. Due to the inclined surface design of the four inclined platforms 30, the inclined platforms 30 squeeze the guide wheels, so that the connector 26 Overcome the upward movement of the reset spring 27. At this time, the No. 1 strip opening 10 is in an open state, and the two No. 2 strip openings 11 are closed. When the four inclined platforms 30 are reset and moved, the reset spring 27 is used to control the connector 26 to reset, and the No. 1 strip piece 24 is controlled to move downward to close the No. 1 strip opening 10, and the No. 2 strip piece 25 is moved downward to open the No. 2 strip opening 11. At this time, the dust gas is ejected through the No. 2 strip opening 11. At the same time, the design of the arc baffle 21 is adopted. The dust gas is guided by the arc baffle 21, so that the dust gas rises and then falls freely. The switching between the two modes is completed through the cooperation of the conveying chamber 9 and the switching member, so that the dust can be accumulated on the surface of the photovoltaic cell body 6 waiting for detection. Repeated control of the conveying cavity can control the dust accumulation thickness, which can simulate the dust accumulation process and optimize the detection process.

When the piston head 53 moves back and forth, the push arm 56 is linked to move, and the four inclined platforms 30 are actively controlled to reciprocate through the push arm 56. In the single movement state of the piston head 53, the gas is introduced into the piston chamber 52 through the No. 1 pipe 58, and the gas is discharged from the piston chamber 52 through the No. 2 pipe 59, and the gas is sent to the center through the pipeline. The dust is quantitatively fed into the area between the batching area 38 and the isolation plate 33 in the channel 44 and the spiral feeder 32 is cooperated. After the gas is fed into the central channel 44 through the No. 2 pipe 59, the sliding column 46 is pushed upward, driving the sealing cover 47 to follow the upward movement to open multiple discharge areas. The gas generated by the high-pressure fan 36 continuously enters the batching chamber 12 through the air inlet pipe 34. At the same time, after the sliding column 46 moves up to a predetermined position, it is separated from the annular cavity 45, so that the gas in the central channel 44 enters the annular cavity 45 and enters multiple spray nozzles synchronously. In the cavity 50, gas is ejected through multiple nozzles, which accelerates the dust disturbance in the batching area 38, can quickly fill the entire batching chamber 12 space, and is conducive to the subsequent dust transportation and transfer. At the same time, when the piston head 53 moves, the design of the control rack 57 and the rotating gear 43 makes the rotating gear 43, the concentric shaft 42 and the multiple toggle bars 41 follow the reciprocating rotation, and can continuously toggle the dust on the batching area 38, further accelerating the dust disturbance effect, prompting the dust to be quickly lifted, and ensuring the efficiency of subsequent dust transportation. In addition, the spray chamber 50 is designed based on the position of the cross arm 49, so that the spray chamber 50 and the toggle bar 41 can be relatively displaced under a single disturbance operation, so that the dust can be fully lifted, avoiding the problem of local dust accumulation. At the same time, under the reciprocating action, the dust can be continuously and stably transported, so that the dust accumulation simulation operation is stable, which is conducive to the subsequent dust simulation accumulation, and it is convenient for the staff to freely set according to the actual situation, which is conducive to fully simulating the outdoor operation of the photovoltaic cell body 6;

[0115] A crank 54 is rotatably arranged on one side of the assembly seat, a rocker arm 55 is hinged between the crank 54 and the piston head 53, and the rocker arm 55 is eccentrically arranged on the crank 54, and a control motor drivingly connected to the crank 54 is installed on the other side of the assembly seat;

[0116] The control unit also includes:

[0118] The control rack 57 is arranged on the push arm 56 and meshes with the rotating gear 43 of the disturbing member to complete the transmission;

[0119] The first pipe 58 is communicatively arranged on one side of the tail of the piston chamber 52. A second one-way valve for controlling the one-way entry of gas into the piston chamber 52 is installed at the end of the first pipe 58, and the first pipe 58 is communicatively connected to the external clean gas source;

[0120] The second pipe 59 is communicatively arranged on the other side of the tail of the piston chamber 52. A third one-way valve for controlling the one-way discharge of gas from the piston chamber 52 is installed at the end of the second pipe 59, and the second pipe 59 communicates with the central passage 44 of the disturbing member through a pipeline. Specifically, a turntable is rotatably installed at the bottom of the central passage 44, and a pipeline communicatively connected to the second pipe 59 is arranged on the turntable.

[0121] The present invention provides a photovoltaic cell detection device, and the specific working principle is as follows: First, open the sealing door 2, then place the photovoltaic cell body 6 to be detected on the adjustment unit for fixation, and then reset the sealing door 2 to complete the closing of the detection chamber 1. By providing a first strip-shaped opening 10 and two second strip-shaped openings 11 on the conveying chamber 9, and setting a switching member to complete the follow-up opening and closing control, based on the organic combination of the switching member and the control unit, through the control of the control unit, the switching control of the first strip-shaped opening 10 and the two second strip-shaped openings 11 can be completed by using the switching member, so that the dust gas falls on the photovoltaic cell body 6 in two ways of direct injection and free fall, which can fully simulate the irregular falling environment of dust, optimize the detection process, and improve the detection accuracy. Through the design of the disturbing member, based on the formation of high-concentration dust gas in the batching chamber 12, under the synchronous control of the control unit, the disturbing member is controlled to perform multi-mode disturbing operations in the batching chamber 12 according to the predetermined movement purpose, so that the dust material can fully spread to complete batching. Subsequently, the dust gas is introduced into the conveying chamber 9 to complete the dust covering simulation operation, and cooperate with the simulation light source 5 to complete the illumination conditions of the photovoltaic cell body 6, which can fully simulate the outdoor use of the photovoltaic cell body 6, so that the overall simulation work can be carried out efficiently and stably, the efficiency of the photovoltaic cell body 6 can be accurately measured, the operating state of the photovoltaic cell body 6 can be fully known, the weaknesses of the photovoltaic cell body 6 can be discovered, which is beneficial to subsequent improvement, and at the same time is beneficial to subsequent reasonable formulation of cleaning plans to ensure the normal operation of the photovoltaic cell body 6, and can reasonably evaluate the power generation state of the photovoltaic cell body 6.
