摘要： The efficiency of a thin film Si solar battery is improved. Between a back face electrode and a transparent conductive film provided on a front face side of the back face electrode, a refractive index adjustment layer is interposed made from a material that has a lower refractive index than that of the transparent conductive film. For example when the transparent conductive film is GZO, SiO2 is interposed between the transparent conductive film and the back face electrode made from Ag. As a result light that penetrates into and is absorbed at the back face electrode is reduced, and the reflectivity of light at the back face electrode is improved.
