What is NOT true about the thermal oxide layer?
A: A thermal oxide layer can serve as a passivation layer.
B: A thermal oxide layer acts as an insulator and forces the electrons to flow in the emitter.
C: It creates a back surface field at the back side of the solar cell and thus it reduces the surface recombination velocity.
D: The oxide layer can be thermally grown.
