Hydrogenated amorphous silicon deposited by high pressure sputtering for HIT solar cells

AuthorsGarcía-Hernández, M. ; Ferrer, F. J.

Citation9th Spanish Conference on Electron Devices (2013)
AbstractHydrogenated amorphous silicon thin films were deposited using a high pressure sputtering (HPS) system. In this work, we have studied the composition and optical properties of the films (band-gap, absorption coefficient), and their dependence with the deposition parameters. For films deposited at high pressure (1 mbar), composition measurements show a critical dependence of the purity of the films with the RF power. Films manufactured with RF-power above 80W exhibit good properties for future application, similar to the films deposited by CVD (Chemical Vapor Deposition) for hydrogenated amorphous silicon.
