Hi Global Champion,

Thanks a lot to your reply. I am just trying to build my understanding on this industry better. Does these producers supply to the PV market or the semiconductor market (or both)? Who are their typical downstream customers

@WongLingSiew

according to different purity of silicon, it can be supplied to semi-conductor industry (electronic-grade silicon) or to PV industry (solar grade silicon)

@globalchampion does GT Solar make that list?

@globalchampion LDK Solar is now a major polysilicon producer as well, arguably the most vertically integrated solar company in the world.
