Abstract:
1. A method of manufacturing a tandem-type thin film photoelectric conversion device comprising the steps of: forming at least one photoelectric conversion unit through sequentially stacking a first one-conductivity type layer, a first photoelectric conversion layer of substantially intrinsic semiconductor and a first opposite-conductivity type layer on a substrate in a deposition apparatus; taking out the substrate having the photoelectric conversion unit from the deposition apparatus to air, wherein a non-doped intermediate layer having a thickness of 5 nm or less is formed subsequently to the step of forming the at least one photoelectric conversion unit on the substrate and then the substrate is taken out to the air; introducing the substrate into a deposition apparatus and carrying out plasma exposure processing on the substrate in an atmosphere of a gas mixture containing an impurity element for determining the conductivity type of the same conductivity type as that of the first opposite-conductivity type layer and hydrogen; forming a conductivity type intermediate layer by additionally supplying semiconductor raw gas to the deposition apparatus; and then forming a subsequent photoelectric conversion unit through sequentially stacking a second one-conductivity type layer, a second photoelectric conversion layer of substantially intrinsic semiconductor and a second opposite-conductivity type layer.
