[0002] A solar cell is a device that directly converts light energy into electrical energy through the photovoltaic effect or a photochemical reaction. The working principle of this photovoltaic effect solar cell is that when sunlight shines on the semiconductor p-n junction region, it will excite the formation of hole-electron pairs. Under the action of the p-n junction electric field, the excitons are first separated into electrons and holes and transported to the cathode and anode respectively. The photo-generated holes flow to the p region, and the photo-generated electrons flow to the n region. Connecting the circuit forms an electric current.
[0003] The development of solar technology has roughly gone through three stages: The first generation of solar cells mainly refers to single-crystalline and polycrystalline silicon solar cells, and their photoelectric conversion efficiencies in the laboratory have reached 25% and 20.4% respectively; the second generation of solar cells mainly includes amorphous silicon thin-film cells and polycrystalline silicon thin-film cells. The third generation of solar cells mainly refers to some new concept cells with high conversion efficiencies, such as perovskite solar cells, which are solar cells that use perovskite-type organometallic halide semiconductors as light-absorbing materials.
[0004] The preparation of perovskite solar cells includes links such as raw material processing, functional layer preparation, and assembly. Among them, during the functional layer preparation process, the perovskite material will form a light-absorbing layer and an electrolyte layer after the coating process. The quality of the coating process will directly affect the quality of the perovskite solar cell. Generally, the coating process can only adjust specific die heads or squeegees and the adjustment is complex. On the other hand, it is difficult to control and monitor the adjustment amount of the die head or squeegee in the coating process.
[0005] Based on the above problems, it is proposed to design a die head and a squeegee adjusting mechanism, which has simple adjustment, the adjustment amount can be controlled and monitored in real time, and it can be applied to a variety of die heads or squeegees. Summary of the Invention

Detailed Embodiment
[0025] The following will describe in detail the embodiments of the present utility model with reference to the drawings.
[0026] As Figures 1-3 shown, a die head and scraper adjustment mechanism includes an adjustment handle 1, a dial indicator 2, a fixed plate 3, an adjustment screw 4, a slide table fixing block 5, a hand-adjustable slide table 6, a die head 7, an adjustment block 8, and a lead screw seat 9. The adjustment screw 4 is installed on the fixed plate 3 through the lead screw seat 9. The top of the adjustment screw 4 is also fixedly installed with an adjustment handle 1. One side of the fixed plate 3 is connected to the adjustment block 8 through the adjustment screw 4. The front end of the adjustment block 8 is connected to the hand-adjustable slide table 6 through the slide table fixing block 5. A die head 7 that can move along the length direction of the hand-adjustable slide table 6 is arranged on the hand-adjustable slide table 6. A dial indicator 2 is installed on the other side of the fixed plate 3. The bottom of the measuring head of the dial indicator 2 abuts against the top of the slide table fixing block 5.
[0027] Actual operation: Rotate the adjustment handle 1. The adjustment screw rod 4 connected to the adjustment handle 1 drives the adjustment block 8 to move up and down. The slide table fixing block 5 connected to the adjustment block 8 also moves up and down, thereby driving the up and down movement of the die head 7. The adjustment amount of the above up and down movement can be measured in real time by the dial indicator 2 installed on the fixed plate 3. That is, when the bottom of the probe of the dial indicator 2 abuts against the top of the slide table fixing block 5, the adjustment amount of the up and down movement of the die head 7 will be displayed on the dial indicator 2. Further, a hand-adjustable slide table 6 is also provided between the slide table fixing block 5 and the die head 7. The die head 7 can move along the length direction of the hand-adjustable slide table 6 to adjust the left and right position of the die head 7.
[0028] On the fixed plate 3 of the present utility model, a lead screw seat 9 is installed. The adjustment screw rod 4 is installed on the lead screw seat 9. The adjustment handle 1 is installed at the top of the adjustment screw rod 4. The lower end of the adjustment screw rod 4 is installed with an adjustment block 8. By rotating the adjustment handle 1 to control the up and down movement of the adjustment screw rod 4, the slide table fixing block 5 installed on the adjustment block 8 also moves up and down, and the die head 7 can also be adjusted up and down, thereby controlling the adjustment amount of the up and down movement of the die head 7. At the same time, the adjustment amount of the up and down adjustment of the die head 7 is measured by the dial indicator 2 at the front end of the fixed plate 3, which can monitor the movement of the die head 7 in real time, improve the adjustment accuracy and adjustment efficiency of the die head 7. Further, the hand-adjustable slide table 6 installed on the slide table fixing block 5 can realize the left and right movement of the die head 7, which is beneficial to the efficient progress of the coating process. The whole mechanism has a simple and compact structure and is also convenient to operate.
[0029] The number of the adjustment screw rods 4 is 2. The threads on the adjustment screw rods 4 can be ordinary threads, or trapezoidal threads, rectangular threads, etc. that are adapted to the lead screw seat 9 and the adjustment block 8. The adjustment screw rods 4 are arranged symmetrically left and right on the fixed plate 3.
[0030] The number of the dial indicators 2 is 2. The dial indicators 2 are located at the front end of the adjustment screw rod 4 and are arranged away from the adjustment screw rod 4. That is, the dial indicator 2 on the same side as the adjustment screw rod 4 is located outside the adjustment screw rod 4, avoiding interference between the movement of the adjustment handle 1 on the adjustment screw rod 4 and the dial indicator 2. The dial indicators 2 are arranged symmetrically left and right on the fixed plate 3.
[0031] Specifically, the setting of the double adjustment screw rods 4 and the dial indicators 2 is beneficial to stably adjust the up and down movement of the die head 7. At the same time, one of the dial indicators 2 can calibrate the other dial indicator 2 to ensure the accuracy of the adjustment amount value when the die head 7 moves up and down, and also ensure the level when the die head 7 moves left and right.
[0032] The manually-adjustable sliding table 6 includes a raised slide rail 61, a slider 62, and a fastener 63. A raised portion 611 is formed on the slide rail 61, and notches 612 are formed on both sides of the raised portion. The notches 612 facilitate the quick entry of the notch 621 of the slider into the raised portion 611. A notch 621 that mates with the raised portion 611 is formed on the slider 62, and the fastener 63 vertically passes through the slider 62 to position the slider 62 on the slide rail 61.
[0033] A fixing plate notch 31 is formed on the fixing plate 3. The fixing plate notch 31 is located between two dial indicators 2. The setting of the fixing plate notch 31 facilitates the locking of the fastener 63 and avoids interference between the fixing plate 3 and the fastener 63. The side of the fixing plate 3 away from the die head 7 is fixed.
[0034] The die heads 7 of the present utility model can all be replaced with scrapers, and the scrapers can also be adjusted vertically and horizontally with respect to the die heads 7.
[0035] The width of the die head 7 is between 13 - 100 mm. Correspondingly, the coating width that the die head 7 can achieve is also 13 - 100 mm. One side of the die head 7 is fixedly installed on the slider 62 by bolts.
[0036] The length dimension of the sliding table fixing block 5 is smaller than the length dimension of the fixing plate 3, which is beneficial for the fixing plate 3 to carry the sliding table fixing block 5.
