Description

The Fraunhofer Institute for Solar Energy Systems ISE is one of the larger institutes of the Fraunhofer Society. In the department of Thermal and Optical Systems materials research is a very strong activity comprising thin film technology and micro and nanostructuring of surfaces in order to modify their optical properties. The micro and nanostructuring group was built up in 1994 and has now 12 members including students.
The optical know-how of the group includes rigorous and scalar diffraction theories as well as ray-tracing, thin film theory and effective medium theories. The core technology used for homogeneous origination of micro and nano structures is interference lithography. Here, Fraunhofer ISE is in a world leading position concerning the size of the homogeneously structured areas (at the moment in the range of half a square metre) and the complexity of the structures. Further processes include thin film application by sputtering, reactive ion etching and replication by casting and hot embossing. Sophisticated equipment for characterisation of optical and topographical properties of surfaces was built up.
Current R&D projects include moth-eye antireflective surfaces, light steering surfaces for daylight and display applications, organic photovoltaic cells, photonic crystal lasers and micro structured optical components for the infrared.
Fraunhofer ISE is playing an active role at conferences concerning diffractive optics (e.g. SPIE and EOS conferences), ultraprecision manufacturing (e.g. EUSPEN conferences) and displays (e.g. SID conferences).
