[0002] The cells in solar cells are usually made of silicon wafers. In order to reduce the reflection of light by the cells, the surface of the silicon wafers needs to be coated during the cell production process to form a coating layer on the surface of the silicon wafer to effectively reduce reflection.
[0003] In order to improve the coating efficiency of the cell, in the cell coating process, several silicon wafers are usually placed in a container and placed in a coating device for coating. Multiple silicon wafers can be coated at one time, which improves production efficiency. However, in actual production, the gaps between silicon wafers in the container are very small, and they are easily stuck together, which can easily cause the silicon wafers to fail to form a coating layer or the coating layer to stick together without drying, affecting the coating effect of the silicon wafer and reducing the product qualification rate.
