Abstract: On a substrate is formed a transparent and conductive front electrode layer, on which is formed a photoelectric conversion unit that generates an electric power by a light. On the photoelectric conversion unit is formed a transparent and conductive film, on which a silver-containing back electrode layer. On the back electrode layer is formed further a back electrode reinforcing film formed by UV-irradiation of, or by heating of, or by heating after UV-irradiation of a layer that is obtained by applying a composition for reinforcing film on the back electrode layer with a wet coating method. Provided are a solar cell module with small deterioration of power generation efficiency even under a high humidity environment and with stable performance for a long period of time and a method that can produce the solar cell module more cheaply.

Abstract: Methods and compositions for depositing a film on one or more substrates include providing a reactor with at least one substrate disposed in the reactor. A liquid precursor solution is provided, where the liquid precursor solution comprises a solid precursor and an aromatic solvent. The solid precursor has the general formula: M(RmCp)2Ln; wherein M is an alkaline earth metal, and each R is independently either H or a C1-C4 linear, branched, or cyclic alkyl group. L is a Lewis base; m is 2, 3, 4, or 5; and n is 0, 1, or 2. The aromatic solvent comprises at least one aromatic ring, and has a greater boiling point than the melting point of the solid precursor. The liquid precursor solution is vaporized to form a precursor solution vapor, and the vapor is introduced into the reactor. At least part of the vapor is deposited onto the substrate to form an alkaline earth metal containing film.
