[0002] With the rapid development of society and economy, the demand for energy is increasing day by day. The depletion of fossil energy and the pollution to the ecological environment seriously threaten the sustainable development of society and economy. Therefore, it is urgent to adopt renewable energy as a substitute. Solar energy, as an inexhaustible green renewable energy, has received widespread attention worldwide. However, solar energy needs to use solar cells to store electricity. In the production and processing of solar cells, solar cells need to be texturized to increase the number of reflections and refractions of light on the surface of the cell, thereby reducing the surface reflectivity. The texturizing machine is an important equipment for manufacturing solar cells. Through chemical reactions, single-crystal silicon wafers with specific crystal orientations are corroded in alkaline solutions to produce many tiny pyramid-shaped appearances on the surface of the silicon wafers, thereby increasing the refractive index of the silicon wafers.
