Abstract

On a glass sheet, undercoating layers and a transparent conductive film containing tin oxide as the main component are formed in this order. The surface of the transparent conductive film is provided with roughness including convex portions and concave portions. The convex portions have a mean diameter in a range between 0.05 &mgr;m and 0.3 &mgr;m and include five convex portions or less with diameters of at least 0.5 &mgr;m per 100 &mgr;m2 of the surface. On the transparent conductive film, a photovoltaic unit and a back electrode are formed, thus obtaining a photoelectric conversion device.
