Abstract :
We present our investigations of solar cell mini modules and metal interconnects using terahertz time-domain spectroscopic imaging. It was demonstrated, that time-domain data can be used to reveal the thickness variation of encapsulating layers and height difference of metal contact surfaces in a vicinity of shunts.
