Although the technology principles seem simple compared to more sophisticated, and well-established pattern technologies (extreme ultraviolet lithography, 193-nm immersion lithography, multibeam electron, lithography), its implementation to high-scale or even medium-scale volume production remains challenging. However, uniform thin-film deposition and efficient light management for solar cells can be achieved on cellulose substrates by transferring well-known surface textures that provide an adequate surface for thin film solar cell deposition and also, provide light scattering properties into the cellulose surface. We show that small diameter, single-walled carbon nanotubes can serve as templates for performing polymer imprint lithography with feature sizes as small as 2 nm − comparable to the size of an individual molecule. UV Nanoimprint is a mechanical molding technique where a template with a speciic 3D relief is brought into intimate contact with an UV-curable resist (AMONIL ® ) spin-coated on top of a substrate.

However this requirement contradicts those for demolding, that needs UV resin with high surface energy to minimise sticking, issue. Nanoimprint lithography (NIL) is an emerging high-resolution parallel patterning method, mainly aimed towards, which electron-beam and high-end photolithography are costly and do not provide suf, nanostructures. In some studies such as in the works of, Continuous R2R NIL with 100-mm imprinting belt proposed by Mäkelä, T., Haatainen, T., Ahopelto, J., Kawaguchi, Y., 2010. Thus, it is crucial to have a low cost and high throughput manufacturing process for nanostructures. The polymer is heated above the so-called glass transition temperature and is thus liquid. In all variants of NIL, a nanostructured mold is brought into contact with the substrate, resulting in a pattern, transfer.
