A mechanical method for producing micro-scale and nano-scale textures that facilitates, for example, the cost-effective production of nanostructures on large-scale substrates, e.g., during the large-scale production of thin-film solar cells. A scratcher (multi-pointed abrasion mechanism) is maintained in a precise position relative to a target substrate such that micron-level features (protrusions) extending from the scratcher's base structure are precisely positioned to contact a surface material layer of the target substrate with a predetermined amount of force, and then moved relative to the substrate (e.g., by way of a conveying mechanism) while maintaining the pressing force such that the micron-level features define elongated parallel nano-scale grooves and/or form nano-scale ridges in the surface material layer (i.e., by mechanically displacing) portions of the surface material layer to form the nano-scale grooves/ridges).
