- pfdietz 8y agoVice is just mistaken, not lying. I will charitably assume the same is true of you. Are you REALLY asking me to prove a negative? Tell me, what purpose do you imagine rare earths serve in silicon PV cells? They are not used as dopants (that's boron and phosphorus). There are no magnets. The glass doesn't require them, nor do the structural metals.
