Introduction
JUNHE®2510 monocrystalline cell sheet alkali polishing auxiliary additive for Perc, Topcon solar cell backside alkali polishing and Topcon solar cell de-winding plating, is a water-soluble, non-toxic and harmless additive in line with environmental requirements. This product can greatly improve the corrosion selection ratio of inorganic alkali on silicon dioxide layer and silicon, and greatly reduce the corrosion of inorganic alkali on silicon dioxide layer or PSG layer while realising the polishing and etching of silicon.
Significantly lower alkali make-up, wide application window, and comfortable in adjusting tower base and back throw temperatures.
