Claim Text:
1. A method for manufacturing a crystalline silicon-based photoelectric conversion device, comprising: forming a first intrinsic silicon-based layer, a p-type silicon-based layer and a first transparent electroconductive layer, in this order on one surface of a single-crystal silicon substrate of a first conductivity type; forming a second intrinsic silicon-based layer, an n-type silicon-based layer and a second transparent electroconductive layer, in this order on the other surface of the single-crystal silicon substrate of the first conductivity type; and carrying out a heat treatment after at least one of the first transparent electroconductive layer and the second transparent electroconductive layer is formed; wherein the first transparent electroconductive layer and the second transparent electroconductive layer are indium tin oxide layers each formed by a sputtering method, and the heat treatment is carried out at a temperature of less than 200° C. under a hydrogen-containing atmosphere.
