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