The texture is formed on a single crystalline silicon substrate (formable sizes: 2 to 3 µm).
One-component type etchant used with adding to alkali.

Keywords: texturing, single crystalline silicon, solar cell, asperity

Features

• One-component type etchant used with adding to alkali
• Texture sizes of 2 to 3 µm can be formed
• Low chemical usage and long pot life
• Improving the conversion efficiency by reducing the reflectance of substrate surface after process
