Abstract
A reflective solar cell substrate comprising a base member composed of a metallic material provided with irregularities at the surface thereof and a buffer layer disposed on said base member so as to cover the entire of said irregularities at the surface of said base member, said buffer layer being composed of a substantially transparent or translucent and conductive material, said buffer layer being provided with irregularities at the surface thereof, and said irregularities at the surface of said buffer layer comprising a plurality of thickened convex portions and a plurality of thinned concave portions, said portions being alternately arranged. The reflective solar cell substrate reflects light reaching the substrate without being absorbed by the optically active layer at an effective angle, whereby the solar cell exhibits improved photovoltaic characteristics.
