Methods for depositing a microcrystalline silicon film layer with improved
deposition rate and film quality are provided in the present invention.
Also, photovoltaic (PV) cell having a microcrystalline silicon film is
provided. In one embodiment, the method produces a microcrystalline
silicon film on a substrate at a deposition rate greater than about 20 nm
per minute, wherein the microcrystalline silicon film has a crystallized
volume between about 20 percent to about 80 percent.
