TEXTURE-ETCHANT COMPOSITION FOR CRYSTALLINE SILICON WAFER AND METHOD FOR TEXTURE-ETCHING (1) |
摘要 |
Disclosed herein is an etching composition for texturing a crystalline silicon wafer, comprising, based on a total amount of the composition: (A) 0.1 to 20 wt% of an alkaline compound; (B) 0.1 to 50 wt% of a cyclic compound having a boiling point of 100°C or more; (C) 0.00001 to 10 wt% of a silica-containing compound; and (D) residual water. The etching composition can maximize the absorbance of light of the surface of a crystalline silicon wafer. |
