The core component of perovskite solar cells is a semiconductor film, namely the perovskite film layer.

[0034] It should be noted that the heating surface of the heating plate 3 faces the perovskite glass substrate 2 , that is, the heating surface is arranged upward.

[0035] In this embodiment, when heating and crystallization are required, the perovskite glass substrate 2 to be heated is arranged on the first adjustment component so that the side requiring crystallization faces the heating plate 3. At the same time, the distance between the perovskite glass substrate 2 and the heating plate 3 can be adjusted by the first adjustment component to reduce the heat transfer time of the heating plate 3 to the perovskite glass substrate 2, so as to change the heating efficiency of the heating plate 3 to the perovskite glass substrate 2. When the distance between the two is small, the heating efficiency of the heating plate 3 to the perovskite glass substrate 2 is fast, and the crystallization efficiency is improved. When the distance between the two is large, the heating efficiency of the heating plate 3 to the perovskite glass substrate 2 becomes slow, and uniform heating and crystallization are slowly performed. It can be adjusted to an appropriate position according to actual needs to meet various heating needs, and the area of ​​the heating surface of the heating plate 3 is greater than or equal to the area of ​​the perovskite glass substrate 2, ensuring that the heating surface of the heating plate 3 covers the perovskite glass substrate 2 during heating, so that it is fully and evenly heated in the box 1, and the temperature uniformity of its crystallization process is ensured.

[0036] Example 2

[0037] As a further improvement to Example 1, Figure 2 As shown, four support columns 8 are provided in the box body 1 along the vertical direction, and the four support columns 8 are arranged in a rectangular shape; the heating plate 3 is connected to the four support columns 8 through a second adjusting component; the second adjusting component is located below the first adjusting component, and the second adjusting component and the first adjusting component adopt the same structure; the first adjusting component is slidably connected to the four support columns 8 along the vertical direction.

[0038] In this embodiment, four support columns 8 are provided in the box body 1 to support the first adjustment component and the second adjustment component, so that the first adjustment component can slide on the support columns 8 to adjust the distance between the perovskite glass substrate 2 and the heating plate 3 to change the heating efficiency. The second adjustment component and the first adjustment component have the same structure, and the heating plate 3 is arranged below the perovskite glass substrate 2 through the second adjustment component, so that the position of the heating plate 3 can be adjusted through the second adjustment component.

[0039] Based on the above implementation, in a preferred implementation, Figure 2 As shown, the first adjustment component includes a first shaft seat 4, a first connecting rod 5, a second connecting rod 6 and a first placement block 7; there are four first shaft seats 4, and the four first shaft seats 4 are respectively sleeved on four support columns 8; every two adjacent first shaft seats 4 are connected by a first connecting rod 5, that is, the four first connecting rods 5 are enclosed to form a rectangle; two oppositely arranged first connecting rods 5 are arranged along the first horizontal direction, and the other two oppositely arranged first connecting rods 5 are arranged along the second horizontal direction, and the first horizontal direction and the second horizontal direction are perpendicular to each other; two second connecting rods 6 are connected between the two first connecting rods 5 along the first horizontal direction, the second connecting rods 6 are arranged along the second horizontal direction, and the second connecting rods 6 are slidably connected to the first connecting rods 5 along the first horizontal direction; two first placement blocks 7 can be slidably connected to each second connecting rod 6, and the top of the first placement block 7 is recessed with a first slot 9 adapted to the peripheral side of the perovskite glass substrate 2, and the perovskite glass substrate 2 is suitable for being arranged between the four first placement blocks 7; wherein, the first shaft seat 4 of the first adjustment component is slidably connected to the support column 8.

[0040] It should be noted that the four first connecting rods 5 are connected to the four first shaft seats 4 in a rectangular shape.

[0041] In this embodiment, the first shaft seat 4 of the first adjustment component is adjusted to slide on the support column 8 to change the distance between the first placement block 7 and the heating plate 3 on the second adjustment component, that is, the distance between the perovskite glass substrate 2 placed on the first placement block 7 and the heating plate 3 is changed. At the same time, according to the size of the perovskite glass substrate 2, the second connecting rod 6 can be adjusted to slide on the first connecting rod 5 along the first horizontal direction to adjust the distance between the two second connecting rods 6, thereby changing the distance between the first placement blocks 7 on the two second connecting rods 6. In addition, two first placement blocks 7 on the same second connecting rod 6 are adjusted to slide on the second connecting rod 6 to change the distance, thereby adjusting the distance between the four first placement blocks 7 distributed in a rectangular shape to adapt to the sizes of different perovskite glass substrates 2. After that, the four corners of the perovskite glass substrate 2 are placed in the first grooves 9 of the four first placement blocks 7, and the placement of the perovskite glass substrate 2 is completed, so as to facilitate heating, convenient placement and removal of the perovskite glass substrate 2, and suitable for a wide range; since the second adjustment component and the first adjustment component adopt the same structure, therefore, it can be obtained by the same logic that the adjustment end of the second adjustment component can be adaptively adjusted according to heating plates of different sizes to adapt to heating plates of different sizes, with a wide range of applications and convenient placement and removal of the heating plate; in addition, the four first placement blocks 7 can be adjusted to move simultaneously in the first horizontal direction or the second horizontal direction, and then the heating plate 3 and the perovskite glass substrate 2 can be adjusted to align in the vertical direction to ensure uniform heating.

[0042] Specifically, Figure 2 As shown, the present embodiment does not impose any specific restrictions on the structure of the first groove 9. The first groove 9 is rectangular and can be adapted to the four corners of the rectangular perovskite glass substrate 2 for easy installation and disassembly. The first groove 9 can also be fan-shaped and can be adapted to connect the four corners of the circular perovskite glass substrate 2. Those skilled in the art can set the shape of the first groove 9 according to the shape adaptability of the actual perovskite glass substrate 2 to be placed. In the present embodiment, the shape of the first groove 9 is preferably rectangular.

[0043] Based on the above implementation, in a preferred implementation, Figure 2 As shown, the first shaft seat 4 of the first adjustment assembly is slidably connected to the support column 8 through a linear bearing 10, and the linear bearing 10 is provided with a fixing handle 11 for fixing the linear bearing 10 on the support column 8.

[0044] In this embodiment, the first shaft seat 4 is slidably connected to the support column 8 through a linear bearing 10, which improves the smoothness of the sliding adjustment of the first shaft seat 4 on the support column 8. After the position is adjusted, it can be fixed on the support column 8 by tightening the fixing handle 11. Conversely, when adjustment is required, the fixing handle 11 can be rotated in the opposite direction to loosen it for sliding.

[0045] Specifically, the tightening handle 11 includes a handle portion and a screw portion; one end of the screw portion is corresponding to the support column 8 and is inserted into the linear bearing 10, and the other end is connected to the handle portion; the screw portion is threadedly connected to the linear bearing 10; when it needs to be fixed, the handle portion is rotated and tightened to make it abut against the support column 8 for fixation, and when adjustment is required, the handle portion is rotated in the opposite direction to make the screw portion away from the support column 8, so as to facilitate the linear bearing 10 to slide on the support column 8.

[0046] Based on the above implementation, in a preferred implementation, Figure 2 As shown, the first connecting rod 5 is connected to the second connecting rod 6 via a first cross optical axis fixing clamp 12 .

[0047] In this embodiment, since the second connecting rod 6 and the first connecting rod 5 are vertically connected, the first cross optical axis fixing clamp 12 is used to facilitate connection of the second connecting rod 6 and the first connecting rod 5, which is convenient for installation and disassembly, and facilitates the sliding of the second connecting rod 6 on the first connecting rod 5. At the same time, the first cross optical axis fixing clamp 12 can also lock the first connecting rod 5 and the second connecting rod 6 to prevent movement after adjusting the position and cause the perovskite glass substrate 2 to loosen, thereby improving stability.

[0048] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3As shown, the first placement block 7 is connected to the second connecting rod 6 via a second cross optical axis fixing clamp 13 ; a third connecting rod 14 is connected between two opposite second cross optical axis fixing clamps 13 on the two second connecting rods 6 .

At the same time, according to the size of the heating plate 3, the fifth connecting rod 17 can be adjusted to slide on the fourth connecting rod 16 along the first horizontal direction to adjust the spacing between the two fifth connecting rods 17, thereby changing the spacing between the second placement blocks 18 on the two fifth connecting rods 17. In addition, the two second placement blocks 18 on the same fifth connecting rod 17 are adjusted to slide on the fifth connecting rod 17 to change the spacing, so as to adjust the spacing of the four second placement blocks 18 distributed in a rectangular shape to adapt to the sizes of different heating plates 3. At the same time, the four second placement blocks 18 can be adjusted so that the heating surface of the placed heating plate 3 can cover the perovskite glass substrate 2. After adjustment, the four corners of the heating plate 3 are placed in the second slots 19 of the four second placement blocks 18, that is, the placement of the heating plate 3 is completed, so as to heat the perovskite glass substrate 2, facilitate the placement and removal of the heating plate 3, and is suitable for a wide range.

At the same time, the third cross optical axis fixing clamp 20 can also lock the fourth link 16 and the fifth link 17 to prevent the movement of the perovskite glass substrate 2 from loosening after the position is adjusted, thereby improving stability.
