C.; (d) a layer of intrinsic amorphous silicon; (e) a second doped layer comprising amorphous silicon, said second doped layer containing a dopant whereby the second doped layer is of a second conductivity type different from the first conductivity type; and (f) a second electrode. The first doped layer may be of either n-type or p-type conductivity. The first doped layer can be formed over the transparent electrode by decomposing a gas mixture comprising SiH.sub.4, an oxygen source gas selected from N.sub.2 O or CO.sub.2, and a dopant, in a hydrogen carrier at a substrate temperature of 150.degree. to 250.degree. C., the amount of hydrogen being from 10 to 50 times the amount of SiH.sub.4, said first doped layer being of a first conductivity type. An interfacial layer of intermediate gap may also be included when the first doped layer is a p-type layer. Also described is a method for the formation of an amorphous silicon-oxide film to be utilized in making the thin-film solar cell.
