Solar Manufacturing Cleaning Applications

Solar (PV) Wafer and Silicon Ingot (Silicon Block) Cleaning Applications

MEI manufactures batch wet processing equipment for photovoltaic (PV) Solar wafer cleaning, etching and drying including these important process steps:

Silicon Wafer Production | Wafer Block | Silicon Ingot Cleaning

• Oxide Etch—for Solar Cell, Ingot, Chunk & Filament
  • Remove contaminated native oxide layer & reduce humidity for re-growth

Solar Cell Cleaning

• Incoming Cell Clean- Solar Wafer Pre Cleaning Oxide Etch
  •  Organic & particle removal to prep surface for next process
• Solar Wafer Saw Damage Removal – Damage Etch removal
  •  Eliminate irregular surface & material defects induced during ingot slices (multi-crystaline)
• Texturization
  •  Create roughened surface to reduce light lost from reflection (monocrystaline)
