The effect of side-chain length on the microstructure and processing window of zone-cast naphthalene-based bispentalenes

The solubilizing side-groups of solution-processable π-conjugated organic semiconductors affect both the crystal structure and microstructure of the respective thin films and thus charge-carrier mobility in devices.

Efficient perovskite solar cells by metal ion doping

Realizing the theoretical limiting power conversion efficiency (PCE) in perovskite solar cells requires a better understanding and control over the fundamental loss processes occurring in the bulk of the perovskite layer and at the internal semiconductor interfaces in devices.

About this collection

We are delighted to announce that the 2020 EES Lectureship has been jointly awarded to Professor Yana Vaynzof and Dr Wooyul Kim. To celebrate, we have put together collections of Yana and Wooyul’s publications in Royal Society of Chemistry journals.

You are currently reading Yana’s collection. You can find Wooyul’s collection here.

Yana is an Associate Professor at the Technical University of Dresden, Germany. Since 2019, she has been the Chair for Emerging Electronic Technologies at the Center for Advancing Electronics Dresden, and the Integrated Center for Applied Physics and Photonic Materials. She received her PhD from the University of Cambridge, UK in 2011, and was previously a junior professor at the University of Heidelberg, Germany (2014-2018).

Her research interests focus on emerging photovoltaics based on organic, colloidal quantum dot and perovskite materials. Her work aims to address the challenges of stability and reproducibility of emerging photovoltaic devices by identifying the causes and developing strategies for the mitigation of these challenges. To achieve this, Yana not only utilizes a broad range of experimental methods, but also develops new spectroscopic techniques and methodologies for the study of material physics of novel semiconductors.

Find out more about her research on her website https://cfaed.tu-dresden.de/cfeet-about and on twitter: @vaynzof

She was the only female recipient of an ERC Starting Grant in the panel PE3 Condensed Matter Physics in 2016, and was also the recipient of the 2018 Walter Kalkhof-Rose Memorial Award for outstanding young researchers in the natural sciences as well as the Fulbright-Cottrell Award for innovation in research and teaching.
