Experimental Physics VI



    Congratulations to David Kiermasch and the Photovoltaic Group, winners of the Outstanding Poster Award of the Chemical and Polymer Physics (CPP) Division of the German Physical Society (DPG).

    The prize sponsored by Park Systems Europe GmbH was awarded in the Annual General Meeting of the CPP Division on 15.03.2018 in Berlin.

    The work entitled “Charge carrier recombination in planar n-i-p and p-i-n perovskite solar cells - the role of interfaces” is a collaboration of the Julius Maximilian University Würzburg, Instituto de Ciencia Molecular of University of Valencia in Spain and Bavarian Center for Applied Energy Research (ZAE Bayern). The work presented at the DPG Spring Meeting Berlin 2018 addressed charge carrier recombination dynamics in vacuum deposited planar n-i-p and p-i-n perovskite solar cells with power conversion efficiencies of 20 % and 17 %, respectively. David and coauthors explained the differences between both types of devices by studying charge carrier recombination dynamics with steady state and transient electrical measurements and attributed them to different recombination rates. The work at ZAE Bayern and University of Würzburg were carried out within the project titled “Potential of Perovskite Photovoltaics: Investigation of relevant physical parameters, material properties and efficiency limiting factors in hybrid perovskite solar cells” (HYPER) funded by the Federal Ministry of Education and Research (BMBF) under 03SF0514A and 03SF0514B.
