Abstract
A thin film photovoltaic device on a substrate is being realized by a method for manufacturing a p-i-n junction semiconductor layer stack with a p-type microcrystalline silicon layer, a p-type amorphous silicon layer, a buffer silicon layer comprising preferably intrinsic amorphous silicon, an intrinsic type amorphous silicon layer, and an n-type silicon layer over the intrinsic type amorphous silicon layer.
