    摘要: Embodiments of the invention include a solar cell and methods of forming a solar cell. Specifically, the methods may be used to form a passivation/anti-reflection layer having combined functional and optical gradient properties on a solar cell substrate. The methods may include flowing a first process gas mixture into a process volume within a processing chamber generating plasma in the processing chamber at a power density of greater than 0.65 W/cm2 depositing a silicon nitride-containing interface sub-layer on a solar cell substrate in the process volume, flowing a second process gas mixture into the process volume, and depositing a silicon nitride-containing bulk sub-layer on the silicon nitride-containing interface sub-layer.
