hi all,
I am a beginner of solar cell, here is the thing.
We know that during CZ or other process, the silicon has been doped as P type silicon, so the produced wafer is already P type wafer, but Why sometimes we still use Boron to dope the P type wafer to be P+ wafer? what is the purpose of doing this?
Thanks:sad:
