Each group of side rod groups includes a plurality of side rods 2 connected between the two support panels 1. A plurality of side rod teeth 21 are sequentially arranged on each side rod 2 along its length direction; each side rod 2 is a hollow structure, and a side rod air outlet 22 communicating with the inner cavity of the corresponding side rod 2 is arranged on each side rod tooth 21.

[0043] It should be noted that each group of side rod groups includes one or more side rods 2, and the number of side rods 2 is not limited here; in this embodiment, each group of side rod groups includes two side rods 2. A plurality of side rod teeth 21 are sequentially arranged on each side rod 2 along its length direction, and the number of side rod teeth 21 on the side rod 2 is adjusted according to the user's demand for the carrying capacity of the carrier basket and is not limited here either.

[0044] As a loading tool for solar cells, when in use, a solar cell is inserted between every two adjacent side rod teeth 21 on the side rod 2. When it is necessary to clean the solar cells, the solar cell flower basket loaded with solar cells is placed into the cleaning equipment, and the inner cavity of each side rod 2 is communicated with a gas source, so that the gas output by the gas source can be ejected towards the solar cells from the side rod air holes 22, so that the surface of the solar cells can be rinsed by combining gas and cleaning liquid in this way.

[0045] The solar cell flower basket provided by this application realizes the function of ejecting gas towards the surface of the solar cells through the side rod 2 with a hollow structure and the side rod teeth 21 with a hollow structure; based on this function, the solar cell flower basket has the following advantages:

[0046] 1. By ejecting gas towards the surface of the solar cells, the flushing force of the cleaning liquid on the surface of the solar cells can be increased, promoting the circulation of the liquid medicine, thereby enhancing the cleaning effect and cleaning efficiency;

[0047] 2. By ejecting gas between two adjacent solar cells, the occurrence of patch phenomenon can be effectively prevented, so that the cleaning liquid can more evenly cover the surface of the solar cells, ensuring the uniformity of the cleaning effect, and at the same time solving the problem of water patches caused by the patch phenomenon;

[0048] 3. After the cleaning is completed, ejecting gas towards the surface of the solar cells can accelerate the drying speed of the solar cells.

Since both the side rod 2 and the bottom rod 3 are hollow structures and air holes are provided on the flower basket teeth, during the cleaning process of the solar cells, the solar cell flower basket can eject gas towards the surface of the solar cells from three directions of the solar cells, so as to further enhance the cleaning effect and cleaning efficiency of the solar cells.

[0052] Referring to Figure 5 and Figure 6 , the side bars 2 within the two sets of side bar groups are staggered, so that the air flow can more evenly cover the surface of the battery cells, and can also make the air flow spray in a staggered manner to prevent the air flow from flushing against each other.

[0053] Referring to Figure 7 and Figure 8 , the battery cell flower basket further includes an air storage cover 4.
