Thin Film Photovoltaic

Thin film PV manufacturer have to adress highest quality in contact and absorber layer deposition. These processes are mainly driven by physical vapour deposition (PVD). To ensure highest efficiency in solar cells following processes have to be monitored:

  • Back contact
  • Front contact
  • Electrodes
  • Absorber layer
  • Buffer or seed layer
  • Passivation layer
  • Antireflective coatings
  • Antiscratch coatings

Testing

  • Sheet resistance
  • Conductivity
  • Thickness
  • Homogeneity
  • Permeability

Applications

  • Deposition process control
  • Tempering process control
  • Quality control
  • Final inspection

Substrate

  • Glass
  • Plastic film

Process

  • S2S
  • R2R

Environment

  • In-vacuo/ In-situ
  • Ex-vacuo/ Ex-situ
