SOLAR CELLS

Highlights

  • Measure both mono and poly silicon surface textures
  • Profile and image both uncoated and AR coated surfaces at ease
  • Provide vital statistics such as Size and Height distribution, and Surface Area Ratio

SURFACE TEXTURE (PYRAMIDS ON MONO-SI)

Texture on Mono-Si

Pyramid size and height distribution histograms as well as vital statistics such as pyramid density and surface are ratio are automatically calculated and reported by Zeta's comprehensive Solar Package software.


SURFACE TEXTURE (ETCHED PITS ON POLY-SI)

Texture on Poly-Si

Etched pits size and depth distribution histograms as well as vital statistics such as pit density and surface area ratio are automatically calculated and reported by Zeta's comprehensive Solar Package software.


METAL FINGER & BUS BAR INSPECTION

Solar "finger" measurement

Zeta's high dynamic range (HDR) imaging system enables precision 3D profiling of high reflective metal fingers on very dark textured surfaces. Critical parameters such as line width, height and volume are automatically calculated.



Solar bus-bar measurement

The innovative HDR imaging system from Zeta is the industry first non-contact optical profiler capable of measuring bus-bar width and height automatically.
