Product Introduction

　　This product is mainly used as a polishing additive for crystalline silicon solar cells, capable of preventing alkali corrosion of the silicon wafer's front silicon dioxide, thereby protecting the PN junction on the front of the silicon wafer, improving the flatness of the back of the solar cell, achieving a good polishing effect on the back, enhancing the passivation effect, and thus improving the conversion efficiency of solar cells. This product has a wide process window, is free of nitrogen and phosphorus, and does not contain easily volatile and toxic substances such as low-carbon alcohols.
