    摘要: At least one of a p type semiconductor layer, an i type amorphous silicon-based photoelectric conversion layer, and an n type semiconductor layer that compose an amorphous silicon-based thin film photoelectric conversion device is deposited under the following conditions. Silane-type gas as a main component of raw material gas which is supplied into a reaction chamber and dilution gas containing hydrogen are used, the flow rate of the dilution gas is four or less times that of the silane-type gas, the partial pressure of the silane-type gas in the plasma CVD reaction chamber ranges from 1.2 Torr to 5.0 Torr, and the distance between a surface of a substrate mounted on an anode electrode and a surface of a cathode electrode ranges from 8 mm to 15 mm. Accordingly, a method of manufacturing an amorphous silicon-based thin film photoelectric conversion device having a superior performance is obtained with an improved efficiency in the use of raw material gas as well as an enhanced deposition rate to achieve improvements in cost and efficiency in production. Even if the dilution gas is not used, the advantages above can be achieved under the same conditions as those described above except for the condition concerning dilution gas.
