Microstructured surfaces are capable of performing many different functions. One important field of use is radiation management in optical systems.

In solar cells, micro or nanometer scale structures assist with capturing and making optimum use of light. In artificial lighting and daylighting elements, they help to improve light outcoupling or direct light in the desired direction, while in display applications they are used for antireflection, polarization, light control or defined scattering.

Microstructures also play a part in modifying non-optical characteristics, for instance in modifying the adhesion, wetting or coefficient of friction of surfaces. At Fraunhofer ISE we work on the modeling, design, production, replication and characterization of large-area micro and nanostructures.
