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

Testing

• Sheet resistance
• Conductivity
• Thickness
• Homogeneity
• Permeability

Applications

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

Substrate

• Glass
• Plastic film

Process

• S2S
• R2R

Environment

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

Types

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