- •
PV module with snail trail was analyzed with destructive and non-destructive method.
- •
It was found that discoloration is due to the formation of Ag2CO3 and AgC2H3O2.
- •
The reactions of produced particles with encapsulant also impact the discoloration.
- •
Snail trail was successfully reproduced under controlled environmental conditions.
