Abstract
The present invention provides a substrate with a transparent conductive layer comprising at least one layer stacked on a supporting substrate, wherein the surface of the transparent conductive layer has a distribution of inclination arctan (df/dx) in the range of sampling length dx between 20 nm and 100 nm when a distance of the surface of said transparent conductive layer from the surface of said supporting substrate is regarded as f being a normal distribution having a kurtosis of −1.2 to 0.5 around 0° and a standard deviation of 20° to 55°, and a photovoltaic element using the substrate. The substrate can be produced at a high yield and a low cost suitable for practical use and has a high reliability. In addition, a photovoltaic element having a high photoelectric conversion efficiency is obtained when the substrate is used in manufacturing it.
