Embodiments of the present invention relate to methods for forming a doped amorphous silicon oxide layer utilized in thin film solar cells. In one embodiment, a method for forming a doped p-type amorphous silicon containing layer on a substrate includes providing a substrate in a processing chamber, supplying a gas mixture having a hydrogen-based gas, a silicon-based gas and a carbon and oxygen containing gas into the processing chamber, the gas mixture having a volumetric flow ratio of the hydrogen-based gas to the silicon-based gas between about 5 and about 15, wherein a volumetric flow ratio of the carbon and oxygen containing gas to the total combined flow of hydrogen-based gas and the silicon-based gas is between about 10 percent and about 50 percent; and maintaining a process pressure of the gas mixture within the processing chamber at between about 1 Torr and about 10 Torr while forming a doped p-type amorphous silicon containing layer.
