In perovskite cells, the perovskite layer serves as the light absorption layer of the perovskite cell, and its quality is closely related to the photoelectric conversion efficiency of the perovskite cell.

[0003] The core process of perovskite battery preparation includes coating, drying and crystallization of perovskite solution. Among them, the perovskite annealing crystallinity is one of the key factors affecting the quality of the perovskite layer. In the prior art, in order to obtain a high-quality perovskite film, after the coating, drying and other treatments of the perovskite solution are completed, it is necessary to anneal it. The common hot plate annealing process transfers heat to the perovskite layer by heat conduction to promote the nucleation and crystallization of the perovskite film. However, when preparing large-sized perovskite batteries, the existing hot plates are large in size and low in heating efficiency in order to meet the large heating area, and the heating temperature is uneven, resulting in poor crystallinity of the perovskite film, thereby affecting the photoelectric performance of the perovskite battery. Utility Model Content

[0004] To this end, the technical problem to be solved by the utility model is to overcome the problems that the existing hot plates for preparing large-size perovskite batteries are large in size, low in heating efficiency, and uneven in heating temperature, which leads to poor crystallinity of the perovskite film and thus affects the photoelectric performance of the perovskite battery.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] It should be noted that the perovskite cell includes a glass substrate and a functional layer attached to one side of the glass substrate, wherein the functional layer includes an electron transport layer, a perovskite light absorption layer, a hole transport layer, etc. Each layer structure belongs to the prior art, and its specific definition is not repeated here. The glass substrate and various functional layers stacked therewith constitute the perovskite cell substrate.

[0029] In one embodiment, after the coating process of the perovskite layer is completed, the substrate needs to be subjected to annealing and heating treatment.

[0030] In the past, the size of perovskite cells was relatively small; accordingly, the size of the hot plate used to anneal and heat the perovskite layer was also relatively small, making it easier to achieve a uniform heating temperature. With the development of perovskite cell technology, the size of perovskite cells is also increasing, for example, 1m×2m, and the area required for annealing and heating is also increasing.

[0031] In the prior art, in order to meet the needs of large-size perovskite batteries, a hot plate is selected for annealing and heating treatment. The hot plate includes a plurality of electric heating tubes arranged in parallel, which are encapsulated in an aluminum shell. Each electric heating tube includes a heating element, an insulating layer and a protective layer arranged in sequence from the inside to the outside. The heating element is used for heating, and its material is usually a nickel-chromium alloy; the protective layer is used to form protection, and its material is usually stainless steel. Since the protective layer and the aluminum shell of stainless steel are both conductive, and the heating element needs to be powered on for heating, in order to avoid leakage during the production process, an insulating layer is provided between the heating element and the protective layer to achieve insulation, and the material of the insulating layer is usually magnesium oxide. Therefore, the overall thickness of the hot plate is relatively large, usually 15mm to 20mm.

[0032] On this basis, the structure of the heat plates being set up layer by layer not only leads to low efficiency of heat transfer and requires a longer time to anneal the perovskite layer, but also occupies a large volume and has low space utilization. In addition, the heating temperature of the heat plate is uneven, with high temperatures near the heating tube and low temperatures far away from the heating tube. At the same time, due to the loss of heat during the layer-by-layer transfer, the problem of uneven temperature is further amplified. This ultimately leads to poor crystallinity of the perovskite film, which affects the photoelectric performance of the perovskite battery.

[0033] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model discloses a perovskite battery heating component, including a first insulating heat-conducting member 10, a second insulating heat-conducting member 20, an electric heating component 30 and a connecting member 40.

[0034] Both the first insulating thermal conductive member 10 and the second insulating thermal conductive member 20 have good electrical insulation and heat resistance, and can achieve insulation and heat conduction. Those skilled in the art can set the specific material according to actual needs, such as ceramics, mica, etc.; they can also set the shape and size according to actual needs. Preferably, it is set to a square structure to adapt to the square shape of the battery substrate. Among them, the first insulating thermal conductive member 10 is provided with a first contact surface 11; the second insulating thermal conductive member 20 is arranged on one side of the first insulating thermal conductive member 10 along the first direction D1, and the second insulating thermal conductive member 20 is provided with a second contact surface 21, and the second contact surface 21 and the first contact surface 11 are arranged opposite to each other. Preferably, the normal vectors of the first contact surface 11 and the second contact surface 21 are parallel to the direction vector of the first direction D1.

[0035] The electric heating component 30 can convert electrical energy into thermal energy when powered on, and the electric heating component 30 is arranged between the first insulating heat conductive member 10 and the second insulating heat conductive member 20. Due to the presence of the first insulating heat conductive member 10 and the second insulating heat conductive member 20, the electric heating component 30 no longer needs to be provided with an additional insulating layer, so that the size of the overall component along the first direction D1 becomes smaller, that is, the component is thinner, the space utilization is improved, and the heat transfer path becomes shorter. This structure can make the heating power smaller and energy-saving, and can achieve heating faster and improve heating efficiency. It also reduces the temperature difference of the heating surface and achieves uniform heating. Those skilled in the art can set a specific electric heating component 30 according to actual needs; preferably, the electric heating component 30 is configured as resistive heating. In some embodiments, the material of the electric heating component 30 is set to nickel-chromium alloy. Those skilled in the art can set the shape and size of the specific electric heating component 30 according to actual needs, such as cylindrical, thin sheet, etc.

[0036] The connector 40 is used for connecting the electric heating component 30 to the first contact surface 11 and the second contact surface 21 in a surface contact manner. Those skilled in the art can set the connector 40 according to actual needs, as long as it can ensure that the electric heating component 30 and the two contact surfaces are connected in a surface contact manner. By setting the connector 40, the structural strength and stability of the component can be effectively improved. The surface contact connection method of the electric heating component 30 can further reduce the temperature difference of the heating surface.

[0037] In actual use, the electric heating component 30 is powered on and converts electrical energy into thermal energy to achieve heat supply. Under the action of the connecting member 40, the electric heating component 30 is surface-contact connected to the first contact surface 11 and the second contact surface 21, and the heat is transferred to the perovskite layer through the first insulating heat-conducting member 10 to achieve annealing heating.

[0038] The perovskite battery heating component described in the utility model provides insulation protection for the electric heating component 30 by setting a first insulating heat conductive member 10 and a second insulating heat conductive member 20, thereby eliminating the insulating layer structure of the traditional heating tube, effectively reducing the size of the component along the first direction D1, improving the space utilization rate of the component, and shortening the heat transfer path. Therefore, the heating power is effectively reduced, which is more energy-saving; heating can be achieved faster, with high heating efficiency; the temperature difference of the heating surface is small, and the heating temperature is uniform. Under the action of the connector 40, the electric heating component 30 is connected to each contact surface in a surface-to-surface contact manner, further reducing the temperature difference of the heating surface and improving the uniformity of the heating temperature. Thereby, the nucleation and crystallization quality and production efficiency of the perovskite film can be improved, and then a perovskite battery with higher photoelectric conversion efficiency can be obtained, which effectively improves the production yield of the finished product and saves production costs.

[0039] Reference Figure 2 As shown, in the perovskite battery heating assembly described in the utility model, in some embodiments, the electric heating component 30 is set to a thin sheet structure. Compared with the electric heating tube with a cylindrical structure, setting the electric heating component 30 to a thin sheet structure can significantly increase the contact area between it and the first contact surface 11, and can more effectively cover the first contact surface 11, so that the heating temperature is uniform, and the consistency of the heating temperature is ensured, thereby improving the nucleation and crystallization quality of the perovskite film. Those skilled in the art can select the shape and size of the electric heating component 30 with a specific thin sheet structure, for example, setting it to multiple strip-shaped thin sheet structures and energizing them separately, or setting it to a coil-shaped thin sheet structure, etc.

[0040] Further, see Figure 4As shown, the perovskite battery heating assembly described in the utility model, in some embodiments, the electric heating component 30 includes a plurality of first heating bends 31 and a plurality of second heating bends 32, the bending directions of the first heating bends 31 and the second heating bends 32 are opposite, and the plurality of first heating bends 31 and the plurality of second heating bends 32 are arranged alternately in sequence, that is, they are arranged in a serpentine shape. In the accompanying drawings, the first heating bend 31 and the second heating bend 32 are separated by dotted lines to indicate the first heating bend 31 and the second heating bend 32. Preferably, the electric heating component 30 also includes two electrical connection parts 33, one end of the electrical connection part 33 is connected to the first heating bend 31 or the second heating bend 32, and the other end is connected to the power supply. The electric heating component 30 with this structure can reduce the number of electrical connection parts 33 while covering the first contact surface 11 as much as possible, thereby improving space utilization. Under the premise that the electric heating component 30 is a thin sheet structure, the processing difficulty of the two heating bends is reduced, and it is easy to achieve a smaller bending radius. The problem of partial point contact heating and breakdown of the electric heating tube with a cylindrical structure is effectively avoided, thereby extending the service life of the component and improving the safety of the component. Those skilled in the art can set the width of the electric heating component 30 of the structure, the spacing between adjacent heating bends, the number of each heating bend, etc. according to actual needs, and will not be repeated here.

[0041] Preferably, refer to Figure 7 As shown, in the perovskite battery heating component described in the utility model, in some embodiments, the dimension H1 of the electric heating component 30 along the first direction D1 satisfies the relationship, 0.01mm≤H1≤0.1mm. The dimension of the electric heating component 30 along the first direction D1 is its thickness; when the dimension H1 of the electric heating component 30 along the first direction D1 is 0.01mm to 0.1mm, it can take into account good structural strength and suitable cost. Those skilled in the art can set the specific dimension H1 according to actual needs, such as 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, etc.; preferably, it is set to 0.05mm, and with two insulating heat-conducting parts, the dimension of the overall component along the first direction D1 is about 2mm.

[0042] Reference Figure 5As shown, in the perovskite battery heating component described in the utility model, in some embodiments, the connecting member 40 includes a connecting glue 41, and the connecting glue 41 is arranged between the first heating bend portion 31 and / or the second heating bend portion 32, and the connecting glue 41 connects the first contact surface 11 and the second contact surface 21 respectively. In the accompanying drawings, the setting position of the connecting glue 41 is indicated by a dotted line frame. For example, the connecting glue 41 is only arranged inside the corresponding heating bend portion, the connecting glue 41 is only arranged between two adjacent heating bend portions, or is arranged at the same time, etc. Preferably, the connecting glue 41 is arranged by dispensing glue to avoid glue overflow while ensuring the connection effect.

[0043] Reference Figure 2 and Figure 6 As shown, in the perovskite battery heating component described in the utility model, in some embodiments, a fastening through hole 22 is provided on the second insulating heat-conducting member 20; the connecting member 40 includes a fastening component 42, and the fastening component 42 passes through the fastening through hole 22 and is connected to the first insulating heat-conducting member 10. Preferably, the fastening component 42 is connected by a threaded structure. By providing the fastening component 42, the two insulating heat-conducting members can be effectively connected; at the same time, the fastening component 42 can also be used to achieve the connection and assembly of the heating component with other components, for example, to achieve a fixed connection with an external shell. Preferably, a connecting glue 41 and a fastening component 42 are provided at the same time to achieve the best connection effect.

[0044] Reference Figure 7As shown, in the perovskite battery heating component described in the utility model, in some embodiments, the dimension H2 of the first insulating heat-conducting member 10 along the first direction D1 satisfies the relationship, 0.9mm≤H2≤1.1mm. The dimension H3 of the second insulating heat-conducting member 20 along the first direction D1 satisfies the relationship, 0.9mm≤H3≤1.1mm. The dimension of the insulating heat-conducting member along the first direction D1 is its thickness, and the dimensions of the two insulating heat-conducting members along the first direction D1 are independent of each other. Taking the dimension H2 of the first insulating heat-conducting member 10 along the first direction D1 as an example, when the dimension H2 of the first insulating heat-conducting member 10 along the first direction D1 is too small, less than 0.9mm, it is too thin and easily damaged; when the dimension H2 of the first insulating heat-conducting member 10 along the first direction D1 is too large, greater than 1.1mm, it is too thick and has slightly poor thermal conductivity. Those skilled in the art can set the specific size H2 according to actual needs, such as 0.91mm, 0.92mm, 0.93mm, 0.94mm, 0.95mm, 0.96mm, 0.97mm, 0.98mm, 0.99mm, 1mm, 1.01mm, 1.02mm, 1.03mm, 1.04mm, 1.05mm, 1.06mm, 1.07mm, 1.08mm, 1.09mm, 1.1mm, etc. Preferably, it is set to 0.975mm to take into account good thermal conductivity and structural strength, so as to match the electric heating component 30, and the size of the overall assembly along the first direction D1 is about 2mm. The size H3 is the same and will not be repeated.

[0045] On this basis, preferably, the dimension H2 of the first insulating heat conductive member 10 along the first direction D1 is smaller than the dimension H3 of the second insulating heat conductive member 20 along the first direction D1. Since the second insulating heat conductive member 20 mainly serves the function of connection and assembly, its dimension H3 is set slightly larger to ensure good structural strength and connection effect. The dimension H2 of the first insulating heat conductive member 10 is related to thermal conductivity. An overly thick first insulating heat conductive member 10 will affect the conduction of heat. Therefore, under the premise of ensuring the overall structural strength, its dimension H2 is set slightly smaller to further improve the thermal conductivity of the assembly, so as to improve production efficiency.

[0046] Furthermore, in the perovskite battery heating assembly described in the present invention, in some embodiments, the materials of the first insulating heat conductive member 10 and the second insulating heat conductive member 20 are both set to mica. Compared with other materials, the first insulating heat conductive member 10 and the second insulating heat conductive member 20 made of mica are insulating and non-conductive, and can meet the thermal conductivity requirements of annealing and heating at 200°C, and also have the advantages of light weight, etc., and are particularly suitable for annealing and heating of the perovskite layer.

[0047] Reference Figure 8As shown, the utility model discloses a perovskite battery heating device, comprising a plurality of perovskite battery heating components as described in any one of the above embodiments. A first heat-dissipating surface 12 is also provided on the first insulating heat-conducting member 10, and the first heat-dissipating surface 12 and the first contact surface 11 are respectively arranged on both sides of the first insulating heat-conducting member 10 along the first direction D1. During heating, the heat of the electric heating component 30 is transferred from the first contact surface 11 to the first heat-dissipating surface 12.

[0048] A plurality of first heat release surfaces 12 are arrayed to form a second heat release surface 51, which is used to provide a heat source to heat the perovskite battery. Each perovskite battery heating component has its own independent temperature controller 60, which is used to control and adjust the temperature of the perovskite battery heating component in which it is located. Preferably, the temperature controller 60 is set as a thermocouple.

[0049] By setting up this structure, the second heat release surface 51 with a relatively large area can be divided into multiple first heat release surfaces 12 with relatively small areas, and each heating component can be independently temperature controlled by setting up a respective independent temperature controller 60, thereby effectively ensuring the temperature consistency of each area of ​​the second heat release surface 51, reducing the surface temperature difference, improving the nucleation and crystallization quality of the perovskite film, and improving the overall production efficiency.

[0050] The perovskite battery heating device described in the utility model includes the perovskite battery heating component described in the above embodiment, so the beneficial effects it has are all possessed by the perovskite battery heating device, which will not be repeated. Those skilled in the art can set the specific number of heating components, array arrangement, temperature control conditions, etc. according to actual needs, which will not be repeated. Preferably, nine heating components are selected and arranged in a 3*3 array.

[0051] Working principle:

[0052] After the perovskite solution is coated and vacuum pre-dried to form a film, the perovskite battery is transported to the heating device for heating by a corresponding transport device, such as a robotic arm. During heating, the perovskite battery is arranged on one side of the second heat release surface 51, and the electric heating components 30 of each heating component are powered on for heating, and the heat is transferred to the perovskite layer through the first contact surface 11 and the first heat release surface 12 in turn to achieve annealing heating. During the heating process, the temperature controller 60 controls the temperature of each heating component in real time to prevent a large temperature difference between the heating components. When the temperature of the corresponding heating component reaches the required temperature, the heating is stopped. The perovskite battery heating device described in the utility model can achieve uniform heating, effectively improve the nucleation crystallization quality and production efficiency of large-area perovskite films, and thus obtain a perovskite battery with higher photoelectric conversion efficiency.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
