Corescan

The Corescan instrument reveals locations where energy is lost in solar cells. It has four scan methods, for four different energy loss types: 

• Corescan (COntact REsistance scan) to locate regions of increased contact resistance of the front side metallisation,
• Shuntscan to locate shunts,
• Voc scan (Open-circuit voltage scan) to locate recombination losses on test cells without front side metallisation,
• LBIC scan (Light Beam Induced Current scan) to locate positions with reduced short-circuit current density.
