Abstract

A composite film for a superstrate solar cell or a substrate solar cell has a transparent conductive film and a conductive reflective film, wherein the transparent conductive film is formed by using a wet coating method to apply a transparent conductive film composition or dispersion containing microparticles of a conductive oxide, the conductive reflective film is formed by using a wet coating method to apply a conductive reflective film composition containing metal nanoparticles, the average diameter of holes occurring at the contact surface of the conductive reflective film on either the side of the photovoltaic layer or the side of the transparent conductive film is not more than 100 nm, the average depth at which the holes are positioned is not more than 100 nm, and the number density of the holes is not more than 30 holes/μm.
