Abstract:
It discloses a texturing method for a diamond wire cut polycrystalline silicon slice, including the following steps: firstly, immersing the diamond wire cut polycrystalline silicon slice into a mixed aqueous solution of an alkali solution and an alkali reaction control agent, removing a damaged layer on a surface of the silicon slice, and then immersing the silicon slice into a hydrofluoric acid solution containing inorganic ions and organic molecules for reaction; secondly, pretreating the polycrystalline silicon surface by a mixed solution of hydrofluoric acid and hydrogen peroxide, adding a pore-forming regulator at the same time, and finally texturing the surface of the silicon slice by a mixed acid solution of hydrofluoric acid and nitric acid.

Claim (Index 10):
The texturing method for the diamond wire cut polycrystalline silicon slice according to  claim 1 , characterized in that in step (4), the concentration of the hydrofluoric acid is 1.5-5 mol/L, and the concentration of the nitric acid is 4-7 mol/
