Abstract
A photovoltaic device has at least one set of amorphous semiconductor layers forming a p-i-n junction structure, wherein at least one of the semiconductor layers having a given thickness, is doped with nitrogen and oxygen to a depth forming at least part of said given thickness. Such a photovoltaic device is fabricated by depositing on a substrate at least one set of amorphous semiconductor layers which form a p-i-n junction structure, and by doping at least one of the layers with nitrogen and oxygen to a depth forming at least part of the thickness of the doped layer.
