Wafers for solar cells are thin slices of crystalline silicon that are used as the base material for the production of solar cells. These wafers are typically made from high-purity silicon, which is melted and then solidified into a large, cylindrical ingot. The ingot is then sliced into thin wafers using a diamond saw, which are then polished to a mirror-like finish. The size of wafers for solar cells has increased over time, with the most common size currently being 156mm x 156mm. However, there are also larger wafers available, with sizes up to 210mm x 210mm. The thickness of these wafers is typically around 200 micrometers, although thinner wafers are also available. Once the wafers for solar cells have been produced, they are then processed to create the solar cells themselves. This involves a number of steps, including the application of a thin layer of anti-reflective coating, the deposition of a layer of metal on the front and back of the wafer, and the creation of a grid of fine lines on the front of the cell to collect the electrical current. Overall, wafers for solar cells are a critical component in the production of solar panels, and their quality and efficiency can have a significant impact on the overall performance of the panel.
