Title:
SOLAR BATTERY SURFACE TEXTURING PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/081876
Kind Code:
A1
Abstract:
A solar battery surface texturing processing method comprises the following steps: a, providing a silicon wafer (1) and an etching agent (2); b, placing the silicon wafer in a reaction chamber in which the etching agent is placed or above the etching agent to perform chemical vapor etching, or immersing the silicon wafer in the etching agent to perform liquid phase etching; and c, repeating step b at least once. In this texturing processing method, better heterogeneity can be formed, and therefore a good porous layer can be obtained for a silicon wafer in another crystal orientation, thereby obtaining a lower luminous reflectance.
