PURPOSE:To form a thin-film body having light transmission by incorporating a specific quantity or less of a monovalent metallic element in a carbonate oxide to the oxides of a specific quantity of lead and chromium and using the mixture as a target. CONSTITUTION:Oxides containing a monovalent metallic element of 80mol% or less calculated in terms of a carbonate oxide to the composition of lead of 30-99.5mol% calculated in terms of PbO and chromium of 0.5-70mol% calculated in terms of Cr2O3 are employed as a target, and a thin-film consisting of the oxides including lead and chromium is shaped in a vacuum. The thin-film is heat treated in an atmosphere containing at least lead. Li, Na, Rb, Cs, Cu, etc. can be used as the monovalent metallic element from which the carbonate oxide must be shape, and electromotive force is hardly generated even on a thin-film composed of not less than 80mol% K2CO3. Accordingly, the thin-film having light transmission is acquired, thus improving the conversion efficiency of the operation of a photoelectric conversion device. |
