What are the ingredients of the cleaning agent used in the solar silicon wafer cleaning process?

The general method is to first clean the silicon wafer with an acidic solution with a composition ratio of H2SO4:H2O2=5:1 or 4:1. The strong oxidizing property of the cleaning solution breaks down and removes organic matter; after rinsing with ultra pure water, use an alkali with a composition ratio of H2O:H2O2:NH4OH=5:2:1 or 5:1:1 or 7:2:1 Cleaning with a chemical cleaning solution, in reason for the oxidation of H2O2 and NH4O
