Steel belts lineup for solar cells and photovoltaic cells production

 

Steel belts with coating                  Band saw substrate

Features of steel belts used for solar cells and photovoltaic cells production
  • Material is stainless steel or SK with high tensile strength and hardness.
  • Thin and wide belts are available for thin film solar cells. Maximum width is 1000mm.
  • Low thermal expansion ratio and heat resistive.
  • Coating is available on the belt surface such as Fuluoroplastic coating, anti abrasion coating, or coating with non-adherent property.  
    These coatings enforce toughness and heat resistive feature of steel belts.
  • For inspection line, too, low-reflectivity coating is effective. Inspection can be done accurately and continuously on the conveyor belt without disturbance of metal reflection.
  • Perforation and vacuum holes are available on belts. Vacuum through these holes set and keep positions of fragile silicon wafers and cells on our metal flat belt.
  • Belts with holes and coating work best in the automatic soldering process, printing process and inspection lines under heat and vacuum.
 
Steel belt functions in solar cells and solar modules production

Belts are used in various process in solar cell and module production.

  • Belt substrates make band saw to cut silicon ingots.
  • Steel belts convey wafer, cells and modules in inspection lines, heating process, soldering process, in vacuum environment and printing lines.
