The Joint Lab BerOSE is a laboratory shared by Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB), Freie Universität Berlin (FU) and Zuse Institute Berlin (ZIB). BerOSE stands for "Berlin Joint Lab for Optical Simulations for Energy Research". The office of the Joint Lab is located at ZIB with a close contact to the research group Computational Nanooptics, where algorithmic and software development is carried out.

The research of Joint Lab BerOSE aims to advance materials for photocatalysis, photovoltaics and photonics, with textures on nanometer scales. To do this, we perform rigorous 3D simulations for functional systems and components. In this endeavour, we profit from the combination of the backgrounds of the various partner institutions in experimental, theoretical and computational research.

The official opening of Joint Lab BerOSE has taken place on February 17, 2015 at ZIB, with several dedicated sessions at the 8th Annual Meeting Photonic Devices (HZB press release).

In collaboration with HZB, a European Workshop on Nanophotonics for Solar Energy: Current Trends and Future Challenges has been held on November 25/26, 2015. Presentations have been given by speakers from the following institutions: Univ. of York (UK), Univ. of Ljubljana (SLO), Ecole Centrale de Lyon (F), Helmholtz-Zentrum Berlin (D), TU Delft (NL), IMEC (BE), Univ. of Jena (D), AMOLF (NL), EPFL (CH), FZ Jülich (D), Fraunhofer ISE (D), KIT (D), Zuse Institute Berlin (D) (HZB press release).

BerOSE Workshop 2015


The Second European Workshop Nanophotonics for Solar Energy will be held on 17 October 2018, as part of Photonic Days Berlin Brandenburg 2018.
