  • Abstract
    A nanoimprint based approach to achieve efficient light management for solar cells on low temperature transparent polymer (PET) films is presented. The imprint-textured PET substrates show excellent light scattering properties and lead to significantly improved incoupling and trapping of the light in the solar cell, resulting in a current density of 12.9 mA/cm2, similar to that on a glass substrate with texture-etched ZnO:Al and only 0.2 mA/cm2 lower than that on Asahi(U)-type TCO glass. An efficiency of 6.9 % was achieved for a flexible thin-film silicon solar cell on low cost transparent PET substrate.
