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.
