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. High deposition rates have been obtained by use of a silent electrical discharge in the gas stream prior to the deposition process.
Solar cells fabricated from these films show open circuit voltages of up to 400 mV but current densities are low. This is attributed to a low hydrogen content in the films. Physical and chemical characterization techniques have been used to identify the limiting factors in the performance of these devices. Further research is proposed to improve the efficiency of the photovoltaic devices.
