Description

Technical Field

[0001] The utility model relates to the technical field of solar cells, in particular to a perovskite solar cell series module. Background Art

[0002] The general method for certifying the efficiency of perovskite solar cells is similar to that of silicon cells, but perovskites are mostly prepared in a small area in a laboratory environment, and the area is mostly below 1 cm. With the change of usage requirements, it is necessary to develop large-size perovskite solar cells to promote industrialization. The gradual increase in device area affects the quality of perovskite film formation, thereby affecting the conversion efficiency of perovskite solar cells. Therefore, a method of connecting multiple single-cell perovskite solar cells in series to prepare a perovskite solar cell module, that is, increasing the effective area of ​​the device on the same substrate, is used to meet usage requirements. In the prior art, a perovskite solar cell series module includes multiple perovskite solar cells and multiple connection units A. The perovskite solar cell includes a substrate B, a conductive layer C, an electron transport layer D, a perovskite light-absorbing layer E, and a carbon electrode F that are stacked in sequence; adjacent substrates B are continuously arranged, and adjacent The conductive layer C, the adjacent electron transport layer D, the adjacent perovskite light absorbing layer E, and the adjacent carbon electrode F are all spaced apart and insulated from each other. A connecting unit A, an extension of the carbon electrode F, is disposed between two adjacent perovskite solar cells, with its ends respectively connected to the carbon electrode F of the perovskite solar cell and the conductive layer C of the adjacent perovskite solar cell, thereby forming a series connection. To achieve both insulation and series connection, on a single side of each perovskite solar cell near the adjacent perovskite solar cell, the conductive layer C needs to protrude from the electron transport layer D, the perovskite light absorbing layer E, and the carbon electrode F to serve as a connecting portion. Because the effective area of ​​a perovskite solar cell is the area of ​​the perovskite light absorbing layer E, this protruding portion cannot contribute to the effective area. Therefore, this arrangement reduces the effective area of ​​the perovskite device on the same substrate, thereby reducing the cell efficiency.

[0003] In order to solve the above technical problems, the Chinese patent with announcement number CN218456635U in the prior art discloses a perovskite solar cell series module, including multiple perovskite solar cells and multiple connection units; the positive poles of two adjacent perovskite solar cells are arranged in opposite directions, and the two ends of the connection unit are respectively connected to the positive pole of the perovskite solar cell and the negative pole of the adjacent perovskite solar cell, so that the two are connected end to end.

[0004] Although the above-mentioned existing technical solutions can increase the effective area of ​​the perovskite device on the same substrate and thus improve the battery efficiency, each group of solar cells and each functional layer thereof are all arranged on the substrate, and the existing solar cells are mostly connected to the substrate or the bottom frame by bonding and bolting. The bonding fixing method usually uses adhesives such as silicone and epoxy resin, and the bolting method uses bolts combined with anaerobic screw glue. These fixing methods are relatively cumbersome and time-consuming, and when a single solar cell is damaged, it cannot be quickly removed from the module for maintenance or replacement, thereby affecting work efficiency.

[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A perovskite solar cell series module includes a frame body 1, a rubber pad 2 is embedded and installed on one side of the frame body 1, multiple groups of solar cells 3 are overlapped on one side of the rubber pad 2, and multiple groups of through holes are arranged at one end of the interior of the rubber pad 2. The solar cells 3 are connected by a locking mechanism. The locking mechanism includes a spring-pressing component and a torsion component. The spring-pressing component is used to lock the position of the solar cell 3 after placement, and the torsion component is used to unlock the position of the solar cell 3. When in use, the device can lock the position of the solar cell 3 after placement through the spring-pressing component, and unlock the position of the solar cell 3 through the torsion component. The device has a simple structure and is easy to operate, which facilitates the staff to quickly assemble or separate the faulty solar cell 3 so that it can be repaired or replaced in time, ensuring the subsequent use effect of the module and further improving work efficiency.

[0025] In this embodiment, if Figure 2 、 Figure 3 and Figure 4As shown, the spring-pressing assembly includes multiple groups of card slots opened inside the frame body 1, the positions of the card slots correspond to the positions of the through holes, a card block 5 is installed at one side of the bottom of the solar cell 3 corresponding to the through hole, the card slot and the card block 5 are slidably connected, the interior of the frame body 1 is provided with a locking groove on one side of the card slot, the inner wall of the locking groove is rotatably connected to multiple groups of rotating rods 6, the rotating rod 6 is rotatably connected to the frame body 1, the outer wall of the rotating rod 6 is located at one end of the inner side of the locking groove and is sleeved with a spring-pressing block 7, a connecting groove is provided on one side of the spring-pressing block 7, and a side of the inner wall of the locking groove is provided with a connecting groove. A fixing plate 8 is installed, and a connecting spring 9 is installed between the inner wall of the connecting groove and the fixing plate 8. The fitting surfaces of the card block 5 and the spring block 7 are both provided with a first slope 10 that fits together. First, after the corresponding solar cell 3 is placed, the card block 5 is pushed into the inner side of the card slot through the through hole and continues to squeeze the rubber pad 2. As the two groups of rubber pads 2 retract, the card block 5 enters the inner side of the locking groove and contacts the spring block 7. The first slopes 10 on the two squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly.

[0026] In this embodiment, if Figure 2 、 Figure 3 and Figure 4 When the clamping block 5 contacts the abutting plate 11, the first slope 10 and the second slope 13 are pressed against each other, forcing the abutting rod to drive the returning torsion spring 12 to retract, so that the abutting plate 11 is completely retracted to the inner side of the retraction groove. When the abutting groove is close to the retraction groove, the abutting plate 11 is popped out to the inner side of the abutting groove by the returning torsion spring 12. At this time, the solar cell 3 is released, and the rubber pad 2 rebounds and drives the clamping block 5 to move back the abutting plate 11 and fix it tightly with the inner wall of the abutting groove, thereby completing the locking of the position of the solar cell 3.

[0027] In this embodiment, if Figure 2 、 Figure 3 and Figure 4As shown, the torsion assembly includes a limit groove opened inside the frame body 1 on one side of the inner wall of the locking groove, the limit groove is connected to the inner side of the locking groove, and the end of the spring block 7 away from the first slope 10 is equipped with a limit plate 14 slidably connected to the limit groove, and the rotating rod 6 extends to the end inside the operating groove and is equipped with a knob 15. Furthermore, when the solar cell 3 needs to be repaired or replaced, twisting the knob 15 can drive one group of rotating rods 6 to rotate accordingly, and the sprocket 16 on the outside thereof will also rotate at the same time, and the chain can drive the other groups of sprockets 16 and the rotating rod 6 to rotate. The rotating rod 6 will drive the spring block 7 to rotate, and the abutment plate 11 will be dragged away from the inner wall of the abutment groove. At this time, the rubber pad 2 is completely reset and rebounded, and the block 5 is bounced up and moved. After the abutment groove and the retraction groove are misaligned, the abutment plate 11 will no longer be stuck in the inner side of the abutment groove. At this time, the solar cell 3 can be removed for maintenance or replacement.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, a linkage groove is provided on one side of the locking groove inside the frame main body 1, and the outer wall of the rotating rod 6 extending to one end of the inner side of the linkage groove is provided with a sprocket 16. Multiple sets of sprockets 16 are connected by chain meshing, and an operating groove is provided on one side of the outer wall of the frame main body 1. The outer wall of the frame main body 1 is hinged with a protective plate 17 through a hinge. The protective plate 17 is slidingly connected to the operating groove, and a magnetic block 4 is embedded in one end of the protective plate 17. An iron block adsorbed by the magnetic block 4 is embedded in the inner wall of the operating groove, and a buckle groove is provided on one side of the protective plate 17. Furthermore, when the locking is completed, the protective plate 17 can be flipped toward the operating groove in conjunction with the hinge to allow it to enter the inner side of the operating groove and engage. At the same time, the magnetic block 4 and the iron block are adsorbed to cover the knob 15 to avoid loosening caused by accidental touch.

[0029] The implementation principle of a perovskite solar cell series module in the embodiment of the present application is as follows: after the corresponding solar cell 3 is placed, the card block 5 is pushed into the inner side of the card slot through the through hole, and the rubber pad 2 continues to be squeezed. As the two groups of rubber pads 2 retract, the card block 5 enters the inner side of the locking groove and contacts the spring block 7. The first slopes 10 on the two squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly. After the card block 5 contacts the abutment plate 11, the first slope 10 and the second slope 13 fit together and squeeze each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract to the inside of the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is popped out to the inside of the abutment groove by the reset torsion spring 12. At this time, the solar cell 3 is released, and the rubber pad 2 rebounds and drives the card block 5 to move back the abutment plate 11 and the abutment plate 11. When the locking is completed, the protective plate 17 can be flipped up toward the operating groove with the hinge to allow it to enter the inner side of the operating groove and engage with the inner side of the operating groove. At the same time, the magnetic block 4 and the iron block are attracted to cover the knob 15 to prevent loosening caused by accidental touch.

[0030] The control method of the present invention is to control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. Moreover, the present invention is used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
