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 4):
The texturing method for the diamond wire cut polycrystalline silicon slice according to  claim 1 , characterized in that in step (2), the inorganic ions include inorganic cations and inorganic anions,\n wherein the inorganic cations are one or more of copper ions, silver ions and silver ammonium ions, and the inorganic anions are chloroauric acid ions and/or nitrate ions.
