Problems solved by technology

It is presumed that this is because a void is formed between the reflective film and the substrate, and light is repeatedly reflected inside the void, resulting in a decrease in reflectance.
In addition, it is speculated that when the reflected light passing through the hole enters the substrate at an incident angle larger than the critical angle, the reflected light is totally reflected at the interface between the hole and the substrate, and the reflected light for this total reflection increases, so the reflectance reduce

Abstract

This invention provides a composite membrane for a super straight solar cell or for a substraight solar cell. The composite membrane comprises a transparent electroconductive film and an electroconductive reflective film. The transparent elctroconductive film is formed by coating a composition or dispersion liquid, for a transparent electrocondutive film, containing fine particles of an electroconductive oxide by a wet coating method. The electroconductive reflective film is formed by coating a composition, for en electroconductive reflective film, containing metallic nanoparticles by a wet coating method. The average diameter of pores, which appear on a photoelectric converting layer-side or transparent electroconductive film-side contact face of the electroconductive reflective film, isnot more than 100 nm. The average depth at which the pores are located is not more than 100 nm. The number density of the pores is not more than 30 pores / [mu]m2.
