Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass, and in particular relates to a perovskite solar cell applied to a photovoltaic glass curtain wall. Background Art

[0002] Photovoltaic systems installed in buildings have become one of the main means of building energy conservation and renewable energy utilization. At present, photovoltaic modules such as crystalline silicon photovoltaic modules or thin-film photovoltaic modules are integrated into the glass curtain wall of buildings as photovoltaic power generation systems to form photovoltaic glass curtain walls that can generate electricity, which have been widely used in new buildings.

[0003] In the current photovoltaic glass curtain wall system, the photovoltaic modules are arranged between the outer transparent tempered glass and the inner transparent tempered glass to form a glass panel, which is usually a frame-type curtain wall. Compared with conventional laminated glass, this structure uses photovoltaic modules instead of the film between the two glasses, so the two glasses cannot be connected using conventional bonding technology. Instead, the glass panels need to be fixed by clamping the four feet of the glass panels with support members. The support members usually include a support located on the inner side of the glass panel for connecting to the keel frame and a pressure plate pressed on the outer side of the glass panel and connected to the support through the joints between the glass panels.

[0004] There are two problems with the above connection method: first, due to the lack of an adhesive structure, once the inner and outer glass panels are broken, they will fall directly to the ground, posing a great safety hazard; second, the connection and disassembly of the inner and outer glass panels are inconvenient, the assembly efficiency is low, and it is not easy to replace a single layer of glass after it is broken. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a perovskite solar cell applied to photovoltaic glass curtain walls, so as to solve the problems that the glass panels in the existing photovoltaic glass curtain walls will break and fall directly to the ground, posing a great safety hazard, and the connection and disassembly of the inner and outer glass panels are inconvenient.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a perovskite solar cell applied to a photovoltaic glass curtain wall, comprising an outer glass plate and an inner glass plate, a plurality of films are bonded between the outer glass plate and the inner glass plate, a perovskite solar cell is sandwiched between the outer glass plate and the inner glass plate around the film, quick-connect buckles are inserted on the outer glass plate, the inner glass plate and the film, the quick-connect buckle comprises a plug-in plate, the two ends of the plug-in plate are respectively connected to an end plate and a clamping plate, the end plate and the clamping plate are respectively pressed against the surfaces of the outer glass plate and the inner glass plate.

[0007] The beneficial effects of the utility model are as follows: the perovskite solar cells are laid on the periphery of the film, and while playing an effective power generation function, the film effectively bonds the outer glass plate and the inner glass plate to prevent the outer glass plate and the inner glass plate from falling off in a large area after being broken; the quick-connect buckles can improve the connection strength of the outer glass plate and the inner glass plate, and can quickly load and unload the outer glass plate and the inner glass plate.

[0008] In order to firmly connect the outer glass plate and the inner glass plate by using the film;

[0009] As a further improvement of the above technical solution: the number of the films is multiple and they are evenly distributed between the outer glass plate and the inner glass plate.

[0010] The beneficial effect of this improvement is that a plurality of films evenly and separately arranged can stably connect the outer glass plate and the inner glass plate.

[0011] In order to effectively improve the connection strength between the outer glass plate and the inner glass plate by using the quick-connect buckle;

[0012] As a further improvement of the above technical solution: the length of the plug-in board is equal to the total thickness of the outer glass plate, the inner glass plate and the film, and the thickness of the perovskite solar cell is not greater than the thickness of the film.

[0013] The beneficial effect of this improvement is that the end plates and the card plates at both ends of the plug-in board can be stably clamped on both sides of the outer glass plate and the inner glass plate under the connection of the plug-in board, so that the outer glass plate and the inner glass plate are firmly clamped on both sides of the perovskite solar cell.

[0014] In order to ensure the convenience of quick-connect buckle installation;

[0015] As a further improvement of the above technical solution: the plug-in board is an arc-shaped plate structure, the number of the plug-in boards is multiple and they are arranged equidistantly around the axis of the end plate, the snap-in plate is a conical arc-shaped plate structure, the upper bottom of the snap-in plate is arranged away from the plug-in board and the outer diameter of the upper bottom of the snap-in plate is not greater than the outer diameter of the plug-in board.

[0016] The beneficial effect of this improvement is that the card plate can be conveniently inserted into the through hole used for plugging in the plug-in board.

[0017] In order to effectively improve the installation safety of the quick-connect buckle;

[0018] As a further improvement of the above technical solution: an internal threaded through hole for threaded connection of a bolt is provided through the end plate, and the outer diameter of the rod of the bolt is equal to the inner diameter of the plug-in board.

[0019] The beneficial effect of this improvement is that the bolts can support the plug-in board after being threadedly connected to the end plate, thereby preventing the plug-in board from deforming inwards under the action of external force and causing the quick-connect buckle to fall off the outer glass plate and the inner glass plate.

[0020] In order to effectively ensure the power generation efficiency of perovskite solar cells;

[0021] As a further improvement of the above technical solution: the perovskite solar cell includes a metal bottom electrode, an electron transport layer, a perovskite light absorption layer, a hole transport layer and a top electrode from bottom to top, and the metal bottom electrode and the top electrode are respectively connected to a first lead and a second lead.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0031] Embodiment 1:

[0032] like Figure 1—5 shows: a perovskite solar cell used in photovoltaic glass curtain walls, comprising an outer glass plate 1 and an inner glass plate 2, a plurality of films 4 being bonded between the outer glass plate 1 and the inner glass plate 2, a perovskite solar cell 3 being sandwiched between the outer glass plate 1 and the inner glass plate 2 on the periphery of the films 4, a quick-connect buckle 5 being inserted on the outer glass plate 1, the inner glass plate 2 and the films 4, the quick-connect buckle 5 comprising a plug-in plate 52, the two ends of the plug-in plate 52 being respectively connected to an end plate 51 and a snap-in plate 53, the end plate 51 and the snap-in plate 53 being respectively pressed against the surfaces of the outer glass plate 1 and the inner glass plate 2, the perovskite solar cell 3 being sandwiched between the outer glass plate 1 and the inner glass plate 2 on the periphery of the films 4, The titanium ore solar cell 3 is laid on the periphery of the film 4. While playing an effective power generation function, the film 4 effectively bonds the outer glass plate 1 and the inner glass plate 2 to prevent the outer glass plate 1 and the inner glass plate 2 from falling off in a large area after being broken; the quick-connect buckle 5 can improve the connection strength of the outer glass plate 1 and the inner glass plate 2, and can be quickly loaded and unloaded on the outer glass plate 1 and the inner glass plate 2. The number of the film 4 is multiple, and it is evenly distributed between the outer glass plate 1 and the inner glass plate 2. The multiple uniformly arranged films 4 can stably connect the outer glass plate 1 and the inner glass plate 2. The length of the plug board 52 is the same as that of the plug board 52. The total thickness of the outer glass plate 1, the inner glass plate 2, and the film 4, the thickness of the perovskite solar cell 3 is not greater than the thickness of the film 4, the plug-in board 52 is an arc-shaped plate structure, the number of the plug-in boards 52 is multiple and they are arranged equidistantly around the axis of the end plate 51, the snap-in board 53 is a conical arc-shaped plate structure, the upper bottom of the snap-in board 53 is arranged away from the direction of the plug-in board 52, and the outer diameter of the upper bottom of the snap-in board 53 is not greater than the outer diameter of the plug-in board 52, the snap-in board 53 can be conveniently inserted into the through hole for plugging the plug-in board 52, and the end plate 51 is provided with an internal threaded through hole for threaded connection bolts 54, and the bolts The outer diameter of the rod 54 is equal to the inner diameter of the plug-in board 52. After the bolt 54 is threadedly connected to the end plate 51, it can support the plug-in board 52 to prevent the plug-in board 53 from deforming inward under the action of external force, thereby causing the quick-connect buckle 5 to fall off from the outer glass plate 1 and the inner glass plate 2. The perovskite solar cell 3 includes a metal bottom electrode, an electron transport layer, a perovskite light absorption layer, a hole transport layer and a top electrode from bottom to top. The metal bottom electrode and the top electrode are respectively connected to a first lead and a second lead. The perovskite solar cell 3 can be processed into a thinner thickness to perform effective power generation between the outer glass plate 1 and the inner glass plate 2.

[0033] The working principle of the technical solution is as follows: the adhesive film 4 is positioned on the outer glass plate 1, and then the perovskite solar cell 3 is laid on the outer glass plate 1 around the film 4, and the lead wire of the perovskite solar cell 3 is led out to the outside of the outer glass plate 1, and then the inner glass plate 2 is bonded to the film 4, and the quick-connect buckle 5 is plugged to connect the outer glass plate 1 and the inner glass plate 2: when inserting the quick-connect buckle 5, first align the clamping plate 53 with the pre-opened slots on the outer glass plate 1 and the inner glass plate 2, and then insert the clamping plate 53 into the slot, and the clamping plate 53 and the plugging plate 53 are squeezed by the inner wall of the slot. 2 produces elastic deformation due to the inward deformation. When the clamping plate 53 passes through the outer glass plate 1 and the inner glass plate 2 as a whole, the clamping plate 53 and the plug-in plate 52 lose the limit of the outer glass plate 1 and the inner glass plate 2 and release the elastic potential energy to restore the initial shape, so that the outer glass plate 1 and the inner glass plate 2 are clamped and fixed by the clamping plate 53 and the end plate 51. Then the operator screws the bolts 54 to the end plate 51. At this time, as the bolts 54 are inserted into the inner side of the plug-in plate 52, the plug-in plate 52 is effectively supported by the bolts 54, which effectively prevents the clamping plate 53 from falling off from the outer glass plate 1 and the inner glass plate 2 due to the inward deformation.
