DESCRIPTION
Silicon powder is a crucial raw material used in the production of solar cells. It is used as the base material for both crystalline and amorphous silicon solar cells. High-purity silicon powder is essential for the production of high-quality solar cells.
Crystalline silicon solar cells are made from pure silicon wafers, which are sliced from a large single crystal of silicon. The raw material for this process is high-purity silicon powder. The powder is melted and then solidified into a single crystal, which is then sliced into wafer-thin slices. These slices are then polished and etched to form the final solar cell.
Amorphous silicon solar cells, on the other hand, are made from silicon powder that is deposited onto a substrate. This process is known as thin-film deposition. The silicon powder is melted and then vaporized onto a substrate, such as glass or plastic. This process produces a thin layer of amorphous silicon, which is then patterned and processed into a solar cell.
In both types of solar cell production, the quality of the silicon powder is critical for the performance of the final product. High-purity silicon powder ensures that the solar cell has high efficiency and long-term stability. Therefore, careful selection of the silicon powder supplier and quality control processes are crucial for the success of solar cell production.
