      abstract     = {In less than 3 years' time, a vast progress in power
                      conversion efficiencies of organometal halide perovskite
                      solar cells has been achieved by optimization of the device
                      architecture, charge transport layers, and interfaces. A
                      further increase in these efficiencies is expected from an
                      improvement in the optical properties via anti-reflection
                      coatings and nanophotonic light management concepts. In this
                      contribution, we report on the development and
                      implementation of a nanophotonic front electrode for
                      perovskite solar cells. The nanostructures were replicated
                      via the versatile and large-area compatible UV-nanoimprint
                      lithography. The shallow design of the used transparent and
                      conductive nanostructures enabled easy integration into our
                      solution-based baseline process. Prototype methylammonium
                      lead iodide perovskite solar cells show an improvement of
                      $5\%$ in short-circuit current density and an improvement
                      from $9.6\%$ to $9.9\%$ in power conversion efficiency
                      compared to the flat reference device.},
