A new strategy to fabricate nanostructured P3HT films for organic solar cells by employing reusable soft replica molds is presented. With a UV-curable PFPE mold, P3HT nanopillars as well as P3HT nanocavity structures are obtained by exploiting the self-replication of replica molds. The method demonstrates the possibility to reproducibly prepare well-defined ordered bulk hetero-junction OPVs using reusable PFPE molds.
