A solar cell formation method, and resulting structure, having a first film and a barrier film over a surface of a doped semiconductor, wherein the optical and/or electrical properties of the first film are transformed in-situ such that a resulting transformed film is better suited to the efficient functioning of the solar cell; wherein portions of the barrier film partially cover the first film and substantially prevent transformation of first film areas beneath the portions of the barrier film.
