Thin Film Photovoltaic

Thin film PV module manufacturer have to adress highest quality in contact and absorber layer deposition. These processes are mainly driven by physical vapour deposition (PVD) and heating cycles close to glass softening point. To ensure highest efficiency in solar module at lowest manufacturing cost following processes have to be monitored:

  • Back contact
  • Front contact
  • Electrodes
  • Buffer or seed layer


  • Sheet resistance
  • Conductivity
  • Thickness
  • Homogeneity
  • Permeability


  • Deposition process control
  • Heating process control
  • Quality control
  • Final inspection


  • Glass
  • Plastic film


  • S2S
  • R2R


  • In-vacuo and ex-vacuo
  • In-situ and ex-situ
  • Inline and offline


  • CdTe
  • CIGS
  • Perovskite
  • Organic (OPV)
  • Tandem

Use Case Back Contact

Sheet Resistance

Thin film Photovoltaic Use Case Back Contact

Organic PV cell manufacutring reqiures smooth back contact electrodes. Eddy Current Technologiy enables monitoring and quality assurence of AgNW deposition processes.

Use Case Cell or Module Integrated TCO Front Contact

Characterizing cell integrated front contacts in a superstarte configuratioin is challenging. Eddy current technologiy utilizes anisotropic properties to separate the electromagnetic field of the front contact  from the electromagnetic field of the back contact. Hence, sheet resistance of cell integrated front contact of a manufacutred thin film PV mdoule can be characterized.
