PhotoVoltaic Anti Reflective Coating Thickness Measurement

Application
  • Reflectance and n & k
  • Thickness of antireflective coating (ARC) on textured (poly-) crystalline silicon solar cell
Wavelength 400-950 nm (1.3-3.0 eV)
Accuracy 104.5 nm (PV-ARC measurement) for 104.8 nm (Reference) SiO2 on c-Si*
(thickness measurement on specular sample*)
Number of layers Up to 3 layers on specular sample (depending on layers)
Thickness range 10 nm ~ 30 μm depending on sample
Data acquisition time < 1 s
Beam spot size 1 mm (optional ~ 50 μm)
Focusing of beam Manual / optional : auto-focus
Sample stage
  • Manual X-Y stage (specify sample size and travel distance) Option:
  • Automatic X-Y stage for mapping (specify sample size and travel distance)
Off-axis microscope Optional
PC, monitor Windows XP system with LCD monitor
software
  • Nano-view developed software for:
  • Multi-layer analysis of reflectance (specular surface)
  • Reflectance measurement of textured surface
  • Single layer analysis of ARC on (poly-) crystalline solar cell (textured surface)
