Three series of alkali polishing additives to improve the quality of solar photovoltaic crystalline silicon cells

In the manufacturing process of solar photovoltaic crystalline silicon cells, the polishing process of the cells is crucial, which directly affects the performance and reliability of the final product. In order to take into account the protection of the front side and improve the reflectivity and flatness of the back side, while reducing the defects on the back side, we have launched the advanced alkali polishing additive AT series.

The AT series additives effectively reduce the use of chemicals by promoting the chemical reaction between alkali and silicon, achieving cost savings while improving the back side reflectivity, ensuring the high flatness of the surface of solar photovoltaic crystalline silicon cells, and reducing the occurrence of back side defects.

In addition, our ST series additives provide an efficient solution to the common scratches and dimensional defects at the ends of solar photovoltaic crystalline silicon cells. In alkaline solution, the ST series can promote the reaction and significantly reduce the height difference of line marks and mechanical damage, thereby fine-tuning and repairing the appearance and size of solar photovoltaic crystalline silicon cells.

For the manufacture of BC/HJT (back contact/heterojunction) solar photovoltaic crystalline silicon cells, we have specially developed the SP series polishing additives. This series of products ensures high flatness of the cell with its excellent polishing ability, and its strong IAOH (initial atomic hydrogen) consumption reduction ability provides strong support for the production of high-efficiency cells.

In short, our new generation of alkaline polishing additives not only improves the overall quality of solar photovoltaic crystalline silicon cells, but also helps customers optimize costs while ensuring product quality. Whether it is to increase the back reflectivity, improve flatness, or solve end scratches and size problems, our solutions can bring innovation to your manufacturing process.
