摘要：
It is to provide a base material for a solar cell, constituted by a stretched film of a composition containing a thermoplastic crystalline resin and inert particles, in which the base material for a solar cell has, on at least one side, a surface that has a center plane average surface roughness Ra of 30 to 500 nm and an average interval between local crests S on the surface of 40 to 5,000 nm, by which the base material for a solar cell provided has a surface capable of providing a light trapping effect and is useful for producing a solar cell exhibiting an excellent photoelectric conversion efficiency upon using as a base material of a thin film solar cell.
