Problems solved by technology
Due to the small spacing between teeth, the current flower basket cannot satisfy the normal elastic deformation of silicon wafers under the influence of external force, resulting in lamination of some silicon wafers when they enter the liquid process.
When the laminate is processed in the liquid, the surface process of the silicon wafer will be uneven, which will affect the effect of the cell; and when the silicon wafer is taken out of the liquid, due to the flow of the surface liquid, two adjacent silicon wafers will stick together. Together, they carry liquid out of the tank
A large number of laminations appear in this process section, which will contaminate the liquid during the process of carrying the liquid to another tank body, causing mixed liquid and affecting the concentration of the solution. The surface is scorched causing the generation of debris

The invention relates to a flower basket device for bearing a plurality of solar cells with the size of 210 mm or above in a manufacturing process. The flower basket device comprises two supporting walls and a plurality of supporting rods. The two ends of each supporting rod are connected with the two supporting walls respectively. Each supporting rod is perpendicular to the supporting wall. The plurality of supporting rods are divided into three groups. The axes of all the supporting rods in each group are positioned in the same virtual plane. The three virtual planes corresponding to the three groups and the two supporting walls can form a cuboid accommodation space with an opening in one side in an enclosing mode. Each supporting rod is provided with a plurality of tooth structures protruding towards the accommodation space, and the tooth spacing of the tooth structures is 6.3 + / -0.02 mm. According to the invention, the tooth spacing of the flower basket device is improved, and thuslamination or collision of adjacent large-size solar cells due to gravity, liquid fluctuation, elastic deformation and the like in various processes is avoided.
Description
technical field [0001] The invention relates to the field of energy, in particular to a flower basket device carrying a plurality of solar cells in a manufacturing process. Background technique [0002] With the accelerated consumption of conventional fossil energy such as coal, oil, and natural gas around the world, and the continuous deterioration of the ecological environment, especially the increasingly severe global climate change caused by greenhouse gas emissions, the sustainable development of human society has been seriously threatened. Countries around the world have formulated their own energy development strategies to deal with the limitation of conventional fossil energy resources and the environmental problems brought about by their development and utilization. Solar energy has become one of the most important renewable energy sources due to its reliability, safety, extensiveness, longevity, environmental protection, and resource adequacy, and is expected to be...
