Abstract

The speed of forming a film of a hydrogenated amorphous silicon (a-Si:H) can be increased by controlling the amount of a supplied energy in relation to the film-forming speed. Application of this technique to the production of a solar cell enables a hydrogenated amorphous silicon solar cell (a-Si:H cell) having a high photoelectric conversion efficiency to be produced at high speeds. The aforesaid controlling procedure comprises adjusting the amount (KJ/g-Si.sub.2 H.sub.6) of an energy to be supplied to a film-forming speed depends mainly upon the flow rate of the gas and is not substantially affected by the amount of the energy.
