Manufacturing Photonic Crystals for Photovoltaic Applications — •Andreas Bielawny, Paul Miclea, Andreas von Rhein, Andreas Redler, Siegmund Greulich-Weber, and Ralf Wehrspohn — University of Paderborn, Department of Physics,

Inpired by the wide range of possible applications of photonic crystals, we are aiming for their contribution to the field of photovoltaics. Whether spectral photonmanagement between a multigap-cell’s different layers or waveguiding in thin film cells, opaline photonic crystals offer a tempting way of producing large scale diffractive elements.

We present our work on fabrication of artificial opals made of Silica or PMMA, with focus on our experimental approaches to the main preparation methods of augmented sedimentation and vertical deposition, closely accompenied by investigation and characterization of their structural and optical properties with electron microscopy and angular resolved spectroscopy. We present some promising applications for their use in photovoltaic energy conversion.
