Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a perovskite photovoltaic module and a packaging device thereof. Background Art

[0002] Perovskite solar cells (PSCs) are a type of solar cell that includes compounds with a perovskite structure. Due to their high cell efficiency, perovskite solar cells are currently the fastest growing solar technology. Perovskite solar cells have the potential to achieve higher efficiency and extremely low production costs, and have become commercially attractive. Compared with silicon cells, perovskite cells have obvious advantages, such as high conversion efficiency and low cost. However, perovskites decompose over time when exposed to moisture, light, heat and oxygen, resulting in a lower service life. Therefore, for perovskite solar cells, the performance of their encapsulation is particularly important and is directly related to their service life.

[0003] The current packaging of perovskite solar cells generally involves packaging the cells between the cover and the back plate, and using EVA film or POE film to press the cells and the cover, and the cells and the back plate together. Before pressing, the gas can be exhausted by vacuuming to ensure the packaging performance of the pressed and bonded packaging. After packaging, a metal frame is used around to reinforce and fix. However, when using this method, due to changes in external environmental temperature, water vapor, corrosion and other problems, cracks are easily generated at the lamination. Water vapor will gradually penetrate into the cracks at the edge of the lamination, thus affecting the service life of the photovoltaic module. It has less impact on silicon cells, but has a greater impact on perovskite cells, thus affecting the service life of the cells.

[0004] Therefore, it is necessary to provide a perovskite photovoltaic module and its packaging device to solve the above problems. Summary of the invention

[0102] When the packaging device of the present invention is packaging, its brief process is as follows: the back plate 1, the bottom POE film 2, the battery chip 3, the upper POE film 5 and the glass cover plate 6 are stacked together. When positioning and stacking, the back plate is adsorbed and fixed by a negative pressure adsorption workbench. Before lamination, the negative pressure suction equipment on the workbench is used to perform vacuum treatment on all sides of the stack to ensure the stability and flatness after lamination. During lamination, the middle lamination mechanism 8 is first used to press down to achieve preliminary lamination of the back plate 1, the bottom POE film 2, the battery chip 3, the upper POE film 5 and the glass cover plate 6. After the preliminary lamination, the first upper POE film edge folding mechanism 9, the second upper POE film edge folding mechanism 10, and the third upper POE film edge folding mechanism are synchronously started. The mechanism 11 and the fourth upper POE film edge folding mechanism 12 make the lifting and adjusting cylinder 20 drive the folding mechanism 13 to move downward to the appropriate folding position, and the folding driver drives the folding drive shaft 26 to rotate, thereby driving the folding actuator arm 23, the folding plate 24 and the folding elastic bending strip 29 to fold. The temperature of the folding actuator arm 23, the folding plate 24 and the folding elastic bending strip 29 is controlled by the heater and the temperature controller. When the folding drive shaft 26 rotates and folds, the folding elastic bending strip 29 first folds the bending part of the upper POE film, and then the folding plate 24 performs subsequent folding operations. In this process, the folding force of the folding elastic bending strip 29 is relatively large, which can ensure the pressing ability of the bending part, and thus ensure the overall packaging performance. After the folding is completed, the intermediate laminating mechanism 8 is further pressed down to complete the subsequent final pressing effect to ensure the lamination effect of the entire package. Then, the edge sealing glue layer 7 is coated on the edges of the glass cover plate, and the frame is clamped on the edges to complete the entire packaging process.

[0103] In the present invention, a corresponding packaging device for perovskite photovoltaic modules is provided. During packaging, the backplane, the bottom POE film, the battery chip, the upper POE film and the glass cover are laminated and pressed together. The first upper POE film edge folding mechanism, the second upper POE film edge folding mechanism, the third upper POE film edge folding mechanism and the fourth upper POE film edge folding mechanism can realize the hot pressing and pressing of the battery cell packaging, and can also realize the adhesive pressing and wrapping of the upper POE film, so that the surrounding extended parts of the upper POE film are folded downward and are integrally adhesively pressed and wrapped around the edges of the backplane, the bottom POE film and the battery chip by hot pressing, thereby improving the overall packaging capability and packaging performance. The present invention performs folding and pressing at the same time as lamination. During folding, when the folding driver drives the folding drive shaft to rotate, the folding elastic bending strip first folds the bending part of the upper POE film, and uses the folding plate to hot-press the surrounding extended parts of the bent upper POE film to achieve integrated hot-pressing and covering. A thermostat is also used to control the temperature to improve the hot-pressing effect. During folding, the elasticity and folding force of the folding elastic bending strip are greater than those of the folding plate, which can ensure the folding effect at the folding part and further ensure the packaging effect.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
