Thermally evaporated methylammonium-free perovskite solar cells
Efficient thermally evaporated MA-free perovskite solar cells are developed by optimising their stoichiometry and annealing procedures.
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.

Fractional deviations in precursor stoichiometry dictate the properties, performance and stability of perovskite photovoltaic devices
Reproducibility issues of perovskite materials and devices stem from their extreme sensitivity to fractional, quite possibly unintentional, deviations in the precursor solution stoichiometry.

Hierarchical C@MoS2@C hollow spheres with active MoS2 nanosheets being sandwiched by carbon layers have been produced using a modified template method.
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.

We report a comprehensive study of the symmetrical 6,13-bis(triisopropylsilylethynyl)tetraazapentacene used as an electron transporting material in organic field-effect transistors deposited by spin/zone-casting.
Structure formation in P3HT/F8TBT blends
The structure evolution of all-polymer solar cells based on the blends of poly(3-hexylthiophene) (P3HT) and poly[(9,9-dioctyluorene)-2,7-diyl-alt-(4,7-bis(3-hexylthien-5-yl)-2,1,3-benzothiadiazole)-2′,2′′-diyl] (F8TBT) was investigated.
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.
