      abstract     = {We present a systematic experimental study on the impact of
                      disorder in advanced nanophotonic light-trapping concepts of
                      thin-film solar cells. Thin-film solar cells made of
                      hydrogenated amorphous silicon were prepared on
                      imprint-textured glass superstrates. For periodically
                      textured superstrates of periods below 500 nm, the
                      nanophotonic light-trapping effect is already superior to
                      state-of-the-art randomly textured front contacts. The
                      nanophotonic light-trapping effect can be associated to
                      light coupling to leaky waveguide modes causing resonances
                      in the external quantum efficiency of only a few nanometer
                      widths for wavelengths longer than 500 nm. With increasing
                      disorder of the nanotextured front contact, these resonances
                      broaden and their relative altitude decreases. Moreover,
                      overall the external quantum efficiency, i.e., the
                      light-trapping effect, increases incrementally with
                      increasing disorder. Thereby, our study is a systematic
                      experimental proof that disorder is conceptually an
                      advantage for nanophotonic light-trapping concepts employing
                      grating couplers in thin-film solar cells. The result is
                      relevant for the large field of research on nanophotonic
                      light trapping in thin-film solar cells which currently
                      investigates and prototypes a number of new concepts
                      including disordered periodic and quasi periodic textures.},
