Electroluminescence & Photoluminescence imaging for fast detection of solar cell and module quality with scientific grade cameras

The following parameters can be investigated and tested by EL or PL imaging with pco cameras:
• microcracks
• edge isolation quality
• material quality
• process parameters:
- emitter diffusion
- texture
- antireflective coating
- firing
- etc.
• lifetime / diffusion length
• series resistance
• shunts
• junction breakdown
