Abstract
An electrically conductive transparent substrate for a solar cell includes: a light-transmitting substrate; an electrically conductive layer facing a face of the substrate and having irregularities at a face opposite to the substrate; and a buffer layer made of a material with a resistance higher than a resistance of a material of the electrically conductive layer and disposed on the irregularities, the electrically conductive transparent substrate satisfying the following expression: 0.02≤d/R≤0.06 at any planar position, where d denotes a thickness of the buffer layer, and R denotes a height of the irregularities.
