This study focuses on optimization of silicon nitride (SiN X ) Anti Reflective Coating (ARC) layer deposited on the front side of industrial Passivated Emitter and Rear Cell (PERC) type solar cells in an industrial tube type plasma enhanced chemical vapor deposition (PECVD) tool. Reflection and thickness optimization studies of ARC layer was carried out through a matrix composed of critical plasma parameters. Characterization of the layers were conducted via ellipsometry and reflectivity measurements for uniform coating with desired thickness and refractive index throughout the boat and within the wafers. Passivation property of our films was also tested through QSSPC lifetime measurements.
