Abstract
This invention is to provide a photovoltaic element capable of improving the production yield in the manufacturing process and the reliability such as the weather resistance and the durability, while also improving the photoelectric conversion efficiency by the light enclosing effect. For attaining such object, the photovoltaic element is featured by a fact that the transparent conductive layer, positioned between the substrate and the semiconductor layers, is provided, at a face in contact with the semiconductor layers, with a fractal structure of a fractal dimension D within a range of 1.01.ltoreq.D.ltoreq.1.20 at least within a dimensional range from 40 to 400 nm.
