Abstract:
A method of manufacturing a silicon-based thin film photoelectric converter,said photoelectric converter comprising one or more photoelectric conversion units formed on a substrate, at least one of said photoelectric conversion units being a polycrystalline photoelectric conversion unit including a semiconductor layer of one conductivity type, a crystalline silicon-based thin film photoelectric conversion layer, and a semiconductor layer of the opposite conductivity type stacked in this order by plasma CVD, wherein said crystalline photoelectric conversion layer is deposited by said plasma CVD under the following conditions: the temperature of the underlying layer is at most 550Â° C.; a gas introduced into a plasma reaction chamber includes a silane-based gas and a hydrogen gas as main constituents, the flow ratio of the hydrogen gas relative to the silane-based gas being 50 times or more; the pressure in said plasma reaction chamber is set to at least 3 Torr; and the forming speed of the film is at least 17 nm/min.
