Edge Isolation System

  • Crystal
  • Thin-film
  • Compounds

A high-powered laser removes a film from substrates of thin-film photovoltaic cells, to prevent insulation and corrosion

Features

  • The film-removal process without using an abrading agent will generate residues of removed films only, thus no cleaning equipment is required.
  • This method significantly reduces particulate emissions, allowing the installation within the clean room.
  • The processing time is drastically shortened.

Comparison with sandblasting

  Edge isolation system Sandblasting + washing
Size Saves space Occupies considerable space
Equipment must be shielded to contain dust
Washing Removes residue using dry cleaners or suchlike Washing process is required
Impact on film No adverse affect on other areas Scattering of abrading agent may damage the film surface, thus reducing module output
Others Very small amount of residue remains on the glass substrate, and post-processing is easy. Even after being washed, some abrading agent may remain on the glass surface, causing problems during the lamination process

Adaptability to specification changes

  • Substrate size change
  • Edge removal width change
  • Additional laser heads, etc

Basic configuration

  • Laser system
  • Loading and unloading conveyers
  • Vacuum pump
  • Chiller
  • Dust collector
