Thin films of hydrogenated amorphous silicon have been prepared by chemical vapour deposition at atmospheric pressure from a mixture of silanes over a heated substrate. This approach provides an alternative method to glow discharge and it has several substantial advantages, including safety and lower costs.

Solar cells fabricated from these films show open circuit voltages of up to 400 mV but current densities are low. This has been attributed to a low hydrogen content in the films.

A wide range of analytical techniques has been established and used to characterise the material and confirm the low hydrogen content as a one of the obstacles to the production solar cell quality films

Modifications to the deposition technique are now proposed.
