Quantifying the Efficiency of Free Charge Generation and Extraction in Polymer-based Bulk Heterojunction Devices
Prof. Dieter Neher, Institute of Physics and Astronomy, University of Potsdam, Germany

The photon-to-charge conversion in organic solar cells comprises several elementary steps, including the formation of interfacial charge-transfer states (CTS) via exciton dissociation at the DA heterojunction, the split-up of these states into free charge carriers, and free charg ... more

Nano on the Spot
Prof. Michael Huth, Physikalisches Institut, Goethe-Universität. Frankfurt am Main

Over the last decade, focused electron beam induced deposition (FEBID) has developed into the most versatile technique for direct writing of nanostructures. It uses a focused electron beam which induces dissociation processes on previously adsorbed precursor molecules on a substr ... more
