      abstract     = {Maintaining efficient light management is an essential part
                      for obtaining high efficiency flexible thin-film solar
                      cells. Transparent plastic films like polyethylene
                      terephthalate (PET) are a cost efficient substrate
                      alternative but also impose additional constraints on the
                      light management approaches available. In this study, we
                      investigate and compare two approaches to prepare substrates
                      with light scattering characteristics. We have developed low
                      temperature ZnO:Al layers, which are fully compatible with
                      PET substrates, and are textured by wet-chemical methods.
                      These low temperature textured ZnO:Al layers implemented in
                      amorphous silicon solar cells on glass substrates result in
                      similar efficiencies as highly optimized high
                      temperature-etched ZnO:Al layers. Nanoimprint lithography
                      was used as an alternative light management approach and we
                      show that an improved solar cell performance can be achieved
                      on flexible PET substrates with both methods. Besides the
                      effect on solar cell performance, pros and cons of both
                      approaches with respect to flexibility in choice of
                      materials and textures, fabrication process, stress
                      evolution, and reproducibility are discussed.},
