Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of perovskite solar cells, and in particular to a method and device for repairing holes in a perovskite layer in a perovskite photovoltaic module. Background Art
[0002] With the continuous advancement of solar cell technology, perovskite solar cells have attracted widespread attention in recent years due to their advantages such as high efficiency, low cost and processability. Perovskite materials have great application potential in the photovoltaic field due to their excellent photoelectric properties.
[0003] At present, in the film structure of perovskite solar cells, such as Figure 1 As shown, the perovskite solar cell mainly uses TCO glass 8 as a substrate, and deposits a hole transport layer 7, a perovskite light absorption layer 6, an electron transport layer 5, and an electrode layer 4 on the TCO glass 8, and then laminates butyl adhesive 2, POE adhesive layer 3 and cover glass 1 for packaging, and finally laminates tempered glass 9 on the back of the TCO glass 8.
[0004] Here, since the perovskite light absorption layer 6 in the perovskite solar cell is mainly prepared by a coating process, during the coating process, due to factors such as low viscosity of the perovskite solution, substrate surface cleanliness, and material wettability differences, the perovskite light absorption layer 6 is very likely to have holes and other undesirable phenomena, such as Figure 2 As shown, holes 13 are very likely to appear in the perovskite light absorption layer 6, resulting in poor appearance uniformity of the perovskite solar cell.
[0005] At present, the above problems are mainly solved by optimizing the coating process of the perovskite layer, such as increasing the pre-coating, or increasing the cleaning frequency of the blade to improve the coating quality. However, increasing the pre-coating wastes the perovskite solution and easily leads to an increase in production costs; increasing the cleaning frequency of the blade will affect the cycle of the coating equipment, thereby affecting production capacity.

DETAILED DESCRIPTION
[0019] As cited in the background technology, in the coating process of the prior art, due to the influence of factors such as the low viscosity of the perovskite solution, the surface cleanliness of the substrate, and the difference in the wettability of the material, the perovskite layer is very prone to holes, resulting in poor uniformity of the appearance of the perovskite solar cell. Therefore, the present invention provides a method for repairing holes in the perovskite layer in a perovskite photovoltaic module, comprising the following steps: First, the spatial information of each hole in the semi-finished perovskite photovoltaic module with the perovskite layer on the top can be obtained. Here, the spatial information may include: the plane coordinates of the hole and the diameter of the hole; then, based on the spatial information of the hole, and the area of the hole to be filled determined by the spatial information of the hole, the filling material is filled into the area of the hole to be filled by inkjet printing to obtain the filled perovskite photovoltaic module semi-finished product. Among them, the filling material can be one of a functional ink and a perovskite solution; finally, the filled perovskite photovoltaic module semi-finished product is cured to obtain the repaired perovskite photovoltaic module semi-finished product. The method for repairing holes in the perovskite layer in the perovskite photovoltaic module of the present invention can fill the holes in the perovskite layer, thereby improving the uniformity and aesthetics of the appearance of the perovskite solar cell and the yield rate of the product.

[0021] Please refer to Figure 3 and Figure 4 An embodiment of the present application provides a system for repairing holes in a perovskite layer involved in a method for repairing holes in a perovskite layer in a perovskite photovoltaic module. The system for repairing holes in a perovskite layer in a perovskite photovoltaic module may include: an optical detection device 14, an inkjet printing device 16, a curing device (not shown in the figure) and a computer device 18.

[0023] The inkjet printing device 16 can be used to fill the holes in the perovskite layer in the semi-finished perovskite photovoltaic module. The inkjet printing device 16 can include a printing needle 17.

[0025] The computer device 18 may be a computer, a server, a server cluster consisting of several servers, or a cloud computing service center.
[0026] In the present application, the computer device 18 can establish a communication connection with the optical detection device 14 and the inkjet printing device 16 via a wired network or a wireless network.
[0027] Please refer to Figure 5 , Figure 5 This is a flow chart of a method for repairing holes in a perovskite layer in a perovskite photovoltaic module provided by an embodiment of the present application. The method for repairing holes in a perovskite layer in a perovskite photovoltaic module may include: Step S1, obtaining spatial information of each hole in a semi-finished perovskite photovoltaic module with a perovskite layer on top. Here, the spatial information may include: the plane coordinates of the hole and the diameter of the hole.
[0028] Among them, Figure 6 As shown, the semi-finished perovskite photovoltaic module with a perovskite layer on the top refers to: using a transparent conductive glass layer 12 as a substrate, preparing a carrier transport layer 11 on one side of the transparent conductive glass layer 12, and then coating the perovskite layer 10 on the side of the carrier transport layer 11 away from the transparent conductive glass layer 12, and performing reduced pressure drying and annealing processes to obtain a semi-finished perovskite photovoltaic module.
[0029] Here, the carrier transport layer 11 may be one of a hole transport layer and an electron transport layer. For example, a transparent conductive glass layer 12 may be used as a substrate, a hole transport layer may be prepared on one side of the transparent conductive glass layer 12, and then a perovskite layer 10 may be prepared on the side of the hole transport layer away from the transparent conductive glass layer 12 to obtain a semi-finished perovskite photovoltaic module; or a transparent conductive glass layer 12 may be used as a substrate, an electron transport layer may be prepared on one side of the transparent conductive glass layer 12, and then a perovskite layer 10 may be prepared on the side of the electron transport layer away from the transparent conductive glass layer 12 to obtain a semi-finished perovskite photovoltaic module, which is not limited in the embodiments of the present application.
[0030] It should be noted that before obtaining the spatial information of each hole in the semi-finished perovskite photovoltaic module with a perovskite layer on the top, qualified perovskite layer samples (that is, perovskite layer samples in the area without holes) and perovskite layer samples in the area with holes can be predefined in the computer device. In this way, the computer device can first define what form of the perovskite layer 10 is a hole, and then quickly and accurately identify the holes in the perovskite layer 10.
[0031] For example, Figure 7 As shown, the left picture is a qualified perovskite layer sample, whose perovskite layer film surface is relatively smooth, while the right picture is a perovskite layer sample with a hole area, which contains more white circular structures, and this white circular structure is the hole.
[0032] In an embodiment of the present application, an optical detection device may be used to perform a first image detection on a semi-finished perovskite photovoltaic module having a perovskite layer on the top to obtain image information of the perovskite layer in the semi-finished perovskite photovoltaic module.
[0033] Here, the optical inspection device may include: an optical inspection scanning camera. For example, the optical inspection scanning camera may be an AOI camera. The optical inspection scanning camera in the optical inspection device may perform a comprehensive scan on the semi-finished perovskite photovoltaic module with the perovskite layer on the top.
[0034] The control system in the optical detection device can control the optical detection scanning camera to move along the X direction, and / or can control the optical detection scanning camera to move along the Y direction to take pictures of the semi-finished perovskite photovoltaic module. Afterwards, the computer device can obtain the image information of the perovskite layer 10 in the semi-finished perovskite photovoltaic module, and then the computer device can compare the image information of the perovskite layer 10 in the semi-finished perovskite photovoltaic module with the normal sample information to determine the plane coordinates of each hole in the semi-finished perovskite photovoltaic module with the perovskite layer on the top and the diameter of each hole.
[0035] Step S2: Based on the spatial information of the hole and the hole area to be filled determined by the spatial information of the hole, inkjet printing is performed on the hole area to be filled using a filling material to obtain a filled perovskite photovoltaic module semi-finished product. Here, the filling material can be one of a functional ink and a perovskite solution.
[0036] In the present application, the computer device can determine at least one of the first hole area to be filled, the second hole area to be filled, and the third hole area to be filled based on the plane coordinates of each hole and the diameter of each hole.
[0037] Here, if the diameter of the hole region to be filled is in the range of 0.1 mm to 2.0 mm, the computer device may determine that the hole region to be filled is the first hole region to be filled; If the diameter of the hole region to be filled is in the range of 2.1 mm to 4.0 mm, the computer device may determine that the hole region to be filled is the second hole region to be filled; If the diameter of the hole area to be filled is greater than 4.0 mm, the computer device can determine that the hole area to be filled is the third hole area to be filled.
[0038] In this application, the staff can use the inkjet printing device to fill the filling material into the hole area to be filled. Before the inkjet printing device fills the filling material into the hole area to be filled, the computer device can synchronously transmit the determined hole spatial information to the inkjet printing device. Afterwards, the inkjet printing device can be positioned above the hole area to be filled based on the hole spatial information to ensure that the subsequent filling material can be accurately filled into the hole area to be filled and tightly combined with the hole wall.
[0039] The printing needle in the inkjet printing device can be moved to the top of the hole area to be filled under the control of the control system in the inkjet printing device, and the filling material is accurately filled into the hole area to be filled by the printing needle. The control system in the inkjet printing device can control the printing needle to move along the X direction, and / or can control the printing needle to move along the Y direction. It should be noted that the number of printing needles can be multiple or single, and the embodiments of the present application do not limit this.
[0040] It should be noted that if the computer device determines that the diameter of the area where a hole is located is less than 0.1 mm based on the plane coordinates of a hole and the diameter of the hole, the inkjet printing device does not need to fill the area where the hole is located.
[0041] In the embodiment of the present application, the filling material can be one of functional ink and perovskite solution. Here, the inkjet printing device can have two storage modules, one storage module can be used to store functional ink, and the other storage module can be used to store perovskite solution. During the preparation process, the staff can select the corresponding storage module according to different needs, and then select the corresponding filling material to complete the filling of the hole. This application will be exemplified by the following two cases: In the first case, when the filling material is functional ink, the functional ink may include: black acrylic or epoxy ink. The staff may use the functional ink in the inkjet printing device to fill the first hole area to be filled, and / or the staff may use the functional ink in the inkjet printing device to fill the second hole area to be filled, and / or the staff may use the functional ink in the inkjet printing device to fill the third hole area to be filled, so as to obtain the first perovskite photovoltaic module semi-finished product after filling.
[0042] Here, if the computer device determines that the hole area to be filled is the first hole area to be filled, 4 μL-30 μL of black acrylic or epoxy ink can be used to perform inkjet printing to fill the first hole area to be filled.
[0043] If the computer device determines that the hole area to be filled is the second hole area to be filled, 40 μL-60 μL of black acrylic or epoxy ink can be used to perform inkjet printing to fill the second hole area to be filled.
[0044] If the computer device determines that the hole area to be filled is the third hole area to be filled, 90 μL-120 μL of black acrylic or epoxy ink can be used to perform inkjet printing to fill the third hole area to be filled.
[0045] In the second case, when the filling material is a perovskite solution, the staff can use the perovskite solution in the inkjet printing device to fill the first hole area to be filled, and / or, the staff can use the perovskite solution in the inkjet printing device to fill the second hole area to be filled, and / or, the staff can use the perovskite solution in the inkjet printing device to fill the third hole area to be filled, so as to obtain a filled second perovskite photovoltaic module semi-finished product.
[0046] Here, if the computer device determines that the hole region to be filled is the first hole region to be filled, 4 μL-30 μL of the perovskite solution can be used to perform inkjet printing to fill the first hole region to be filled.
[0047] If the computer device determines that the hole region to be filled is the second hole region to be filled, 40 μL-60 μL of the perovskite solution may be used to perform inkjet printing to fill the second hole region to be filled.
[0048] If the computer device determines that the hole region to be filled is the third hole region to be filled, 90 μL-120 μL of the perovskite solution may be used to perform inkjet printing to fill the third hole region to be filled.
[0049] Step S3, curing the filled semi-finished perovskite photovoltaic module to obtain a repaired semi-finished perovskite photovoltaic module.
[0050] It should be noted that, when different filling materials are selected, the time and method for curing the filled semi-finished perovskite photovoltaic module are also different. This application will be exemplified by the following two optional implementation methods: In a first optional implementation, when the filling material is a functional ink, the functional ink is used to fill the hole area to be filled, so as to obtain the first perovskite photovoltaic module semi-finished product after filling, and then the first perovskite photovoltaic module semi-finished product can be subjected to a first curing treatment to obtain the repaired first perovskite photovoltaic module semi-finished product. Here, the first curing treatment refers to: curing treatment using UV light irradiation. For example, the time of the first curing treatment can be 1 minute.
[0051] In this case, after using functional ink to accurately fill the area with holes to be filled and performing a first curing treatment on the filled area, the uniformity of the appearance of the perovskite solar cell can be ensured, and the existence of the holes is difficult to see with the naked eye.
[0052] A second optional implementation method is that when the filling material is a perovskite solution, the perovskite solution is used to fill the hole area to be filled to obtain a filled second perovskite photovoltaic module semi-finished product, and then the second perovskite photovoltaic module semi-finished product can be subjected to a second curing treatment to obtain a repaired second perovskite photovoltaic module semi-finished product. Here, the second curing treatment refers to curing treatment by baking with an IR infrared lamp. For example, the time of the second curing treatment can be 20 minutes, and the temperature of the second curing treatment can be 120°C-130°C.
[0053] In this case, after using the perovskite solution to accurately fill the area to be filled with holes and performing a second solidification treatment on the filled area, not only can the uniformity of the appearance of the perovskite solar cell be ensured, but after the perovskite solution is filled into the holes and a second solidification treatment is performed, the integrity of the perovskite layer can also be ensured, thereby improving the photoelectric conversion efficiency of the perovskite solar cell.
[0054] In the present application, after obtaining the repaired first perovskite photovoltaic module semi-finished product or the second perovskite photovoltaic module semi-finished product, an optical inspection device 14 can be used to perform a second image inspection on the repaired first perovskite photovoltaic module semi-finished product or the second perovskite photovoltaic module semi-finished product to determine whether the repaired perovskite photovoltaic module semi-finished product is qualified.
[0055] Here, the optical inspection device 14 can be the same as the device for the first image inspection. If the repaired perovskite photovoltaic module semi-finished product is judged to be qualified, it can flow into the next process. If the repaired perovskite photovoltaic module semi-finished product is judged to be unqualified, the above-mentioned repair method steps can be repeated for repair.

[0057] Here, those skilled in the art can understand that the specific operations of each module in the above-mentioned perovskite photovoltaic module hole repair device have been described in the above reference. Figures 5 to 7 The method for repairing holes in the perovskite layer in a perovskite photovoltaic module has been described in detail, so its repeated description will be omitted.
