In the field of solar cell manufacturing, wafer bonding machines are mainly used for battery coating and bonding processes. Solar cells are usually composed of multiple components that need to be precisely positioned and arranged, and wafer bonding machines allow for the bonding of cell components under high precision control. At the same time, the wafer bonding machine can also deal with the surface optical characteristics of solar cells, such as improving the reflectivity and light transmission. The high precision and high reliability of wafer bonding machine are very important to the manufacturing of solar cells, which is why wafer bonding machine is widely used in the manufacturing of solar cells.
