[0002] In the process of preparing solar cells, slit coating technology is mainly used to coat perovskite precursor solution, electron transport layer and hole transport layer. Slit coating technology coats the wet film in a non-contact manner to obtain a wet film with controllable thickness while ensuring that the original substrate is not damaged. The thickness and uniformity of the wet film will affect the efficiency of the final product.
[0003] Usually, in order to obtain appropriate film thickness and sufficient uniformity, manual adjustment is required before operating the coater. At the same time, if the machine moves or a large vibration occurs, it needs to be adjusted again. The adjustment of existing coaters usually involves testing and adjusting limited points on a surface to achieve the desired data. During the final measurement, it will be found that the actual film thickness and uniformity in some places are significantly different from the ideal data. For this reason, it is necessary to design an adjustment device for coating feedback and substrate spacing during wet film coating. Utility Model Content

However, one or more embodiments may also be implemented by those skilled in the art without these specific details.
[0026] like Figure 1-Figure 4 As shown, a device for adjusting the distance between coating feedback and substrate in coating wet film comprises a marble platform 100, a processing mechanism 200 is fixedly connected to the top of the marble platform 100, and an adjusting mechanism 300 is fixedly connected to the surface of the processing mechanism 200;
[0027] The processing mechanism 200 includes a slide rail 210, which is fixedly connected to the top of the marble platform 100. A gantry 220 is slidably connected to the surface of the slide rail 210. A fixed beam 290 is fixedly connected to the inner side of the gantry 220. Short rods 230 are rotatably connected to the two ends of the inner side of the fixed beam 290. There are two short rods 230. A beam a240 is rotatably connected between the two short rods 230. A slider 250 is slidably connected inside the beam a240. There are two sliders 250. A coating head 260 is rotatably connected between the two sliders 250. A displacement sensor 270 is fixedly connected to the surface of the coating head 260. A sample table 280 is arranged in the middle of the top of the marble platform 100. A guide groove is provided inside the beam a240. The surface of the slider 250 is slidably connected to the inside of the guide groove. There are two fixed beams 290, and the two fixed beams 290 are symmetrically distributed on the inner side of the beam a240.
[0028] Furthermore, a rotating hole is opened inside the fixed beam 290, and the surface of the coating head 260 is rotatably connected to the inside of the rotating hole. The fixed beams 290 on both sides will move up and down accordingly to ensure that the distance between the coating head 260 and the sample stage will be within the allowable error during the entire coating process. During the coating process, even if the sample stage 280 is slightly tilted, it can be adaptively adjusted according to the distance of the specific displacement sensor 270 after multiple operations, so that the inclination of the sample stage 280 can be accurately grasped in subsequent operations. During operation, the coating head 260 can be adaptively adjusted according to the inclination so that the lower end of the coating head 260 has sufficient parallelism with the sample stage to meet the process requirements for making perovskite solar panels. Compared with the existing method, there is no need to use manual adjustment even if a new environment is changed.
[0029] Furthermore, the adjustment mechanism 300 includes an insertion strip 310, which is fixedly connected to one end of the slider 250, and a socket 320 is fixedly connected to one end of the insertion strip 310, a spring 330 is fixedly connected to one side of the socket 320, a T-shaped rod 340 is fixedly connected to one end of the spring 330, a T-shaped strip 350 is fixedly connected to one end of the T-shaped strip 340, a positioning rod 370 is fixedly connected to one end of the T-shaped strip 350, a positioning strip 360 is fixedly connected to the inner side of the gantry 220, a positioning hole is provided inside the positioning strip 360, and the surface of the positioning rod 370 matches the inside of the positioning hole.
[0030] Furthermore, a through hole is opened inside the socket 320, and one end of the surface of the T-shaped rod 340 passes through the through hole opened inside the socket 320. Pressing the T-shaped rod 340 drives the T-shaped bar 350 to move, thereby driving the positioning rod 370 to disengage from the positioning bar 360. After that, the socket 320 and the insertion strip 310 can be moved up and down, thereby driving the slider 250 to slide up and down and perform fine-tuning, and can be fixed after the fine-tuning is completed.
[0031] The working principle of the device for adjusting the coating feedback and substrate spacing in the coating wet film of the utility model is as follows: before the coating starts, the coating head 260 is lowered so that the displacement sensor 270 can measure the distance from the sample stage 280 to the displacement sensor 270. At this time, the distance from the bottom of the coating head 260 to the sample stage 280 can be calculated according to this distance. During the coating process, the coating head 260 moves forward, and the data measured by the displacement sensor 270 will be fed back in real time. When the measured distance deviation exceeds the expected range, the fixed beams 290 on both sides will move up and down accordingly to ensure During the entire coating process, the distance between the coating head 260 and the sample stage 280 will be within the allowable error. During the coating process, even if the sample stage 280 is slightly tilted, after multiple runs, adaptive adjustment is performed according to the distance of the specific displacement sensor 270, so that the inclination of the sample stage 280 can be accurately grasped in subsequent runs. During the operation, adaptive adjustment is performed according to the inclination so that the lower end of the coating head 260 and the sample stage 280 have sufficient parallelism to meet the process requirements for making perovskite solar cells. Compared with the existing ones, manual adjustment is not required even if a new environment is changed;
[0032] In addition, when adjusting, pressing the T-shaped rod 340 drives the T-shaped bar 350 to move, and then drives the positioning rod 370 to separate from the inside of the positioning bar 360, and then the socket 320 and the insertion bar 310 can be moved up and down, and then the slider 250 can be driven to slide up and down and fine-tune, and it can be fixed after the fine-tuning is completed.
[0033] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
