Silicon nitride (a‐SiN x :H) films deposited by the expanding thermal plasma at high rate (> 1 nm/s) have been studied for application as anti‐reflection coatings for multicrystalline silicon (mc‐Si) solar cells. Internal quantum efficiency measurements have revealed that bulk passivation is achieved after a firing‐through process of the a‐SiN x :H as deposited from NH 3 /SiH 4 and N 2 /SiH 4 plasmas. However, the a‐SiN x :H films deposited from N 2 /SiH 4 show a lower passivation quality than those deposited from NH 3 /SiH 4 . This has been attributed to a poorer thermal stability of the films deposited from the N 2 /SiH 4 plasma, resulting in structural changes within the film during the firing step.
