      abstract     = {We present a nanoimprint based approach to achieve
                      efficient light management for solar cells on low
                      temperature transparent polymer films. These films are
                      particularly low-priced, though sensitive to temperature,
                      and therefore limiting the range of deposition temperatures
                      of subsequent solar cell layers. By using nanoimprint
                      technology, we successfully replicated optimized light
                      trapping textures of etched high temperature ZnO:Al on a low
                      temperature PET film without deterioration of optical
                      properties of the substrate. The imprint-textured PET
                      substrates show excellent light scattering properties and
                      lead to significantly improved incoupling and trapping of
                      light in the solar cell, resulting in a current density of
                      12.9 mA/cm2, similar to that on a glass substrate. An
                      overall efficiency of $6.9\%$ was achieved for a flexible
                      thin-film silicon solar cell on low cost PET substrate.},
