In order to prepare ideal pyramid texturing of Si(100) wafers surface, the surface texturing of as-cut mono-crystalline silicon wafer, acid polishing silicon wafer and alkaline polishing silicon wafer were studied by chemical etching in NaOH/Na2SiO3·9H2O/IPA system, NaOH/IPA system and Na2CO3/NaHCO3 system, respectively. The surface microstructures and reflectances were characterized. The results show that acid polishing silicon wafer with smooth and flat surface can form uniform and compact pyramid texturing after alkaline etching system with NaOH/Na2SiO3·9H2O/IPA, and which possesses low reflectivity.
