[0002] Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. Solar cell modules are the main components for photovoltaic power generation. Solar cell modules are photovoltaic power generation equipment made of solar cells connected in series and parallel and hot-pressed and sealed with tempered glass, EVA and TPT.

[0003] For example, the Chinese utility model patent with the announcement number "CN218335951U" discloses a solar cell assembly, which is convenient for the solar tracker to track the sun by cooperating with the adjustable mounting bracket, and controlling the rotating motor of the fixing seat to drive the U-shaped mounting frame to rotate horizontally and the steering motor of the U-shaped mounting frame to drive the solar cell assembly body to rotate vertically for angle adjustment, so that the main optical axis of the solar cell assembly body is always parallel to the sunlight, so that the solar cell assembly is always aimed at the sun from sunrise to sunset, so as to improve the utilization rate of solar energy.

[0004] However, in the above patent, although the structure of the prior art can use solar cell modules and solar cell panels to track the rotation of the sun and improve the utilization rate of solar energy, during the actual use of such devices, the exterior of the solar cell modules and solar cell panels are often easily contaminated by external dust, thereby reducing the efficiency of the solar cell panel's photoelectric conversion.

[0033] The present application is further described in detail below through drawings and examples.

[0034] Reference Figures 1 to 4The embodiment of the present application provides a solar cell assembly with high photoelectric conversion efficiency, including a solar cell group 1 and a support frame 2 for flipping and adjusting the solar cell group 1. The solar cell group 1 includes a mounting frame 101 and a transparent sealing plate 102 with solar cells installed inside. The upper surface of the mounting frame 101 is provided with a cleaning mechanism 4 for cleaning the surface of the transparent sealing plate 102. The cleaning mechanism 4 includes a cleaning shaft 410 and guide rails 401 symmetrically installed on the upper surface of the mounting frame 101. Two sets of guide rails 401 are slidably connected to the cleaning shaft 410.

[0035] The cleaning shaft 410 includes a connecting rod 411 and a cleaning sponge sleeve 412 . The cleaning sponge sleeve 412 is sleeved on the outer surface of the connecting rod, and a counterweight ring is fixedly installed at the center of the connecting rod 411 .

[0036] Both ends of the connecting rod 411 respectively penetrate the interior of the two sets of guide rails 401 , and both ends of the guide rails 401 are provided with magnetic blocks 402 magnetically connected to the connecting rod 411 .

[0037] The connection between the two ends of the connecting rod 411 and the limiting slide groove is provided with a slow-down ring 414 to improve the friction force. The two ends of the connecting rod 411 are threadedly connected to the limiting nut 415 at the places where they pass through the guide rail 401. By turning the solar cell group 1 to track the angle of solar radiation, the cleaning shaft 410 in the cleaning mechanism 4 can be driven to slide downward under the limit of the guide rail 401, so that the cleaning sponge sleeve 412 on the surface of the connecting rod 411 wipes and cleans the surface of the solar cell group 1. In this process, the cleaning sponge sleeve 412 on the surface of the connecting rod 411 is provided at the center of the connecting rod 411. The setting of the heavy ring 413 can assist the cleaning shaft 410 to move downward stably and roll. During the downward rolling process, the limit nuts 415 at both ends of the guide rail 401 and the connecting rod 411 can limit the sliding and rolling of the cleaning shaft 410. The setting of the retarding ring 414 at both ends of the connecting rod 411 can increase the friction between the connecting rod 411 and the guide rail 401, reduce the speed of the cleaning shaft 410 when it moves and rolls, and avoid the cleaning shaft 410 from rolling too fast and being unable to effectively clean the dust on the surface of the solar cell group 1.

[0038] Reference Figure 1 and Figure 2 In one aspect of the present application, connection blocks 103 rotatably connected to the support frame 2 are symmetrically arranged on both sides of the bottom of the mounting frame 101, and the support frame 2 includes an integrally arranged connection plate 202 and two groups of support plates 201 rotatably connected to the connection blocks 103.

[0039] A servo motor 203 that drives the connecting block 103 is fixedly installed on the inner side of a group of support plates 201, and a solar tracker 104 that is electrically connected to the servo motor 203 is arranged on the outer side of the mounting frame 101. When the solar cell is in use, the electrical connection between the servo motor 203 and the solar tracker 104 can control the rotation of the servo motor 203, driving the connecting block 103 to rotate a certain angle, so that the solar cell group 1 is flipped following the angle of the sun's radiation.

[0040] Reference Figure 2 and Figure 3 In one aspect of the present application, a detachable fixing seat 3 is installed at the bottom of the support plate 201, and the fixing seat 3 includes an integrated support plate 301 and two groups of bolt fixing blocks 302. A threaded spindle 303 is penetrated at the inner center of the support plate 201, and the lower end of the threaded spindle 303 is fixedly connected to the support plate 301. Two groups of semi-ring limiting grooves 204 are symmetrically opened inside the support plate 201, and two groups of limiting rods 304 penetrating the semi-ring limiting grooves 204 are symmetrically arranged on both sides of the threaded spindle 303.

[0041] The tops of the threaded main shaft 303 and the two sets of limiting rods 304 are threadedly connected with locking nuts 305, and the interior of the bolt fixing blocks 302 are provided with pre-installed holes 306 for external fixing. When the solar cell is in use, the combination of the threaded main shaft 303 and the limiting rod 304 can assemble and fix the support frame 2 and the fixing seat 3. Through the sliding of the limiting rod 304 in the semi-ring limiting groove 204, the staff can adjust the use direction of the support frame 2 and the solar cell group 1 according to seasonal changes, further improving the photoelectric conversion efficiency of the solar cell. The support frame 2 can be fixed on the fixing seat 3 by tightening the locking nut 305, and the locking nut 305 can be moved outward and loosened, so that the limit between the support frame 2 and the fixing seat 3 can be easily released, so that the staff can conveniently disassemble, inspect and maintain the solar cell group 1 and the cleaning mechanism 4 on the support frame 2.

[0042] Working principle: During the use of the solar cell assembly with high photoelectric conversion efficiency, the fixing seat 3 should first be fixed to the desired installation position by connecting the screws with the pre-installed holes 306 in the bolt fixing block 302, and then the support frame 2, the solar cell group 1 and the cleaning mechanism 4 should be assembled in sequence according to the design to form a complete solar cell. After the assembly is completed, the threaded main shaft 303 and the locking nut 305 on the outside of the limiting rod 304 are loosened in sequence, and the direction of the support frame 2 and the solar cell group 1 and the fixing seat 3 are adjusted according to the season and the geographical location of the installation point. During the adjustment process, the semi-ring limiting groove 204 limits the position of the limiting rod 304 and the support frame 2. After the adjustment is completed, the three The locking nuts 305 are tightened to fix the directions of the support frame 2 and the solar cell group 1. At this time, the solar cell is installed and can be put into use. During the use of the solar cell assembly, the solar tracker 104 and the servo motor 203 are used in conjunction with each other to drive the solar cell group 1 to flip back and forth according to the angle of sunlight. When the flipping angle is large, under the action of the counterweight ring 413, the cleaning shaft 410 in the cleaning mechanism 4 slides from the upper end of the guide rail 401 to the lower end, wipes and cleans the outer surface of the solar cell group 1 that receives sunlight, removes dust on the surface of the solar cell group 1, and ensures the efficiency of photoelectric conversion of the solar cell assembly.
