Description

Technical Field

[0001] This utility model belongs to the field of perovskite battery processing equipment, and relates to a heat preservation cavity, specifically a heating and heat preservation cavity for a perovskite battery substrate annealing equipment. Background Technology

[0002] Perovskite solar cells (i.e., perovskite-type solar cells) are thin-film solar cells that use perovskite-type organometal halide semiconductors as photoelectric conversion materials. They generally include a substrate, a conductive material layer, a first carrier transport layer, a perovskite layer, a second carrier transport layer, a top electrode layer, etc. The materials on the substrate can be defined as the coating layers of the perovskite solar cell.

[0003] Chinese invention patent application number 202410352512.8 discloses a perovskite battery annealing apparatus, annealing method, and perovskite battery annealing equipment, including a heat-releasing element and a heating assembly. The heat-releasing element has a heat-releasing surface, which is positioned facing the perovskite battery to be heated for heating the perovskite battery, and a gap exists between the heat-releasing surface and the perovskite battery. The heating assembly is connected to the heat-releasing element and is used to provide a heat source to the heat-releasing element. A sealed cavity is formed between the heating assembly and the heat-releasing element, and the heating assembly heats the heat-releasing element through the cavity without opening it. This perovskite battery annealing apparatus, annealing method, and perovskite battery annealing equipment heats the perovskite layer through a heat-free heating method, resulting in excellent temperature uniformity on the perovskite battery. However, this apparatus requires a complex heat-releasing element and heating assembly, which are structurally complex and extremely costly, and there is still room for improvement in the uniformity of heat distribution. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a heating and insulation cavity for a perovskite battery substrate annealing device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a heating and insulation cavity for a perovskite battery substrate annealing equipment, which has at least one set of independent insulation cavity units, wherein the insulation cavity unit includes:

[0006] A sealing mechanism, the sealing mechanism comprising an outer housing having an inlet at the top and an upper sealing door that can be opened and closed at the inlet;

[0007] A material receiving mechanism, which is installed inside the outer casing, is used to support the material fed in through the inlet;

[0008] A heat equalization mechanism, comprising a flow guide shroud spaced from the inner wall of the outer shell to form a flow cavity, a fan rotatably mounted within the flow cavity, and a fan motor connected to the fan to drive its rotation.

[0009] The air guide cover has an air inlet structure and an air outlet structure arranged opposite to each other.

[0010] Ideally, the air inlet structure and the air outlet structure are independently arranged as an array of through holes.

[0011] Furthermore, the air inlet structure and the air outlet structure correspond independently to the material.

[0012] Furthermore, the closure mechanism also includes a side-sealing door that can be opened and closed and mounted on the side of the housing.

[0013] Furthermore, the enclosure mechanism also includes multiple support feet mounted on the bottom of the housing.

[0014] Ideally, the material-bearing mechanism includes two sets of support frames installed inside the housing and spaced apart, multiple reinforcing brackets connected between the inner wall of the housing and the corresponding support frames, and multiple lining pads installed on the support frames.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The heating and heat preservation cavity of the perovskite battery substrate annealing equipment of this utility model, by adopting a specific structure of sealing mechanism, material support mechanism and heat equalization mechanism, can use the heat equalization mechanism to evenly dissipate the heat generated by the heater to the heat preservation cavity unit, thereby improving the uniformity of annealing heating and thus improving the quality of perovskite battery substrate. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the heating and insulation cavity of the perovskite battery substrate annealing equipment of this utility model. Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] like Figure 1 The heating and insulation chamber 2 of the perovskite battery substrate annealing equipment shown has at least one set of independent insulation chamber units; in this embodiment, there are two sets that are connected adjacently, so that different heating process requirements can be met (such as annealing and cooling treatments respectively).

[0019] The insulation cavity unit mainly includes a cooperating sealing mechanism 21, a heat equalization mechanism 22, and a material support mechanism 23.

[0020] The sealing mechanism 21 includes an outer shell 211 with a feed inlet at the top and an upper sealing door that can be opened and closed at the feed inlet. Material 1' can be placed into the outer shell 211 through the feed inlet using a conventional material transfer structure (this material transfer structure is not part of the insulation chamber unit and is not the inventive point of this application). The connection between the upper sealing door and the outer shell 211 can be conventional, such as a pivot connection, as long as it can achieve sealing and heat insulation of the outer shell 211. In this embodiment, the sealing mechanism 21 also includes a side sealing door 212 that can be opened and closed on the side of the outer shell 211. The installation method and requirements of the side sealing door 212 are the same as above. The sealing mechanism 21 also includes multiple support feet 210 installed at the bottom of the outer shell 211 to stably support the heating and insulation chamber of the perovskite battery substrate annealing equipment on the ground.

[0021] The material support mechanism 23 is installed inside the outer casing 211 to support the material 1' fed in through the inlet (which can be a large-size perovskite solar cell or a corresponding substrate; the specific number of material 1' is not limited, and it can be one piece or multiple stacked pieces). The material support mechanism 23 can be a conventional one, as long as it can support the material 1'. In this embodiment, the material support mechanism 23 includes two sets of support frames 231 installed inside the outer casing 211 and spaced apart, multiple reinforcing brackets 232 connected between the inner wall of the outer casing 211 and the corresponding support frames 231, and multiple supporting pads 233 installed on the support frames 231; other structures are preferred to enable simultaneous support of multiple layers of material 1', thereby improving production efficiency.

[0022] The heat equalization mechanism 22 includes a flow guide 222 (which may be an integral structure, possibly containing multiple parts, or composed of multiple parts) spaced apart from the inner wall of the outer shell 211 to form a flow cavity 223, a fan 224 rotatably mounted in the flow cavity 223 (rotatable in a conventional manner, in which the fan 224 has a horizontally arranged mounting shaft, as long as it can be ensured that the fan 224 rotates around the mounting shaft as the axis of rotation, such as by bearing mounting; when the fan 224 rotates, a local negative pressure is generated in the flow cavity 223 and airflow is generated), and a fan motor 225 connected to the fan 224 to drive its rotation (for example, the fan motor 225 can be mounted on the outer wall of the outer shell 211 to fix the fan motor 225). The air guide shroud 222 has an air inlet structure and an air outlet structure arranged opposite to each other (the air inlet structure and the air outlet structure are independently corresponding to the material 1'). The air inlet structure and the air outlet structure are independently arranged through-hole arrays, which can ensure the stability of air inlet and outlet and further improve the heating effect. The area and number of through-hole arrays can be conventionally adjusted or selected according to actual heat exchange requirements, internal temperature requirements of the outer shell 211, and other factors. The top of the outer shell 211 is usually equipped with a heater (not shown in the figure) in a conventional manner, so that the heater is located above the material 1'. Preferably, there is a certain structure between the material 1' and the heater to separate them (the heater and the flow cavity 223 can cooperate, and when the impeller 224 rotates, the heat generated by the heater can be introduced into the flow cavity 223), to avoid the heater directly heating the material 1', but the flow cavity 223 can be used to uniformly heat the material 1', thereby improving the quality of the perovskite battery substrate.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
