Postdoctoral Researchers and Research Fellows

 
 

Terry Chien-Jen Yang

Linjie Dai

 
Terry received his PhD in Photovoltaic Engineering (2016) from UNSW in Sydney, Australia. He recently joined StranksLab as a Marie Skłodowska-Curie postdoctoral fellow working on lightweight and flexible all-perovskite multijunction solar cells. Previously, he worked on perovskite-silicon tandem solar cells at CSIRO Energy in Australia (2019-2021) and PV-Lab, EPFL in Switzerland (2017-2019). His research interests include: perovskites, crystalline silicon, tandem/multijunction solar cells, and the materials science of other photovoltaic technologies. Started June 2021. Linjie received his PhD in Physics from Cambridge in 2021 for his work on ultrafast carrier dynamics in perovskites under the supervision of Prof. Neil C. Greenham. He joined StranksLab as a postdoc working on perovskite scintillators for medical imaging. By following ultrafast electronic and structural dynamics using transient absorption/photoluminescence/radioluminescence spectroscopy, he investigates fundamental loss mechanisms in semiconductors and discovers materials with desirable optoelectronic properties for high-efficiency solar cells, light-emitting diodes and X-ray detectors. Started June 2021.
   

 

 

Milos Dubajic

Dengyang Guo

Milos obtained his BSc and MSc in Electrical Engineering from the University of Belgrade, Serbia. His master’s studies focused on designing novel, lossless metamaterial structures. During his PhD at UNSW, Australia, he focused on applying light, X-ray and neutron spectroscopic techniques for the characterization of electron and phonon dynamics of novel photovoltaic materials. He joined StranksLab as a postdoc to explore how strain manipulation in metal halide perovskites could lead to improvements in their optoelectronic performance. Dengyang received his PhD under supervision of Dr. Tom J. Savenije from TUDelft, where he studied charge carrier dynamics in metal halide perovskites. His interest is on analyzing fundamental properties of optoelectronic materials and quantifying the connection between the material property and device performance. Started January 2021.
   

Youngkwang Jung

Simon Kahmann

Youngkwang obtained his PhD in Materials Science & Engineering under supervision of Prof. Aron Walsh at Yonsei University, Korea. In September 2022, he joined the group as a Marie Curie Postdoctoral Fellow working on defect-strain relationships in halide perovskites. His research involves materials simulations on the basis of first-principles density functional theory (DFT) using high-performance computing. Beyond bulk properties – electronic, vibrational, optical, and transport – his interests include point and extended defects including surfaces and interfaces. Simon’s work focuses on photophysics and optoelectronic properties of novel semiconductors. He received a double-doctorate from the University of Groningen and the Friedrich-Alexander University Erlangen-Nuremberg under the supervision of Maria A. Loi and Christoph J. Brabec for his studies on nanomaterials for optoelectronic applications. He started working on tin-based and two-dimensional perovskites as a postdoc in Groningen. Started January 2021 as a DAAD research fellow.

Bart obtained a PhD (AMI, Switzerland) for his work on degradation and
aging mechanisms in perovskite solar cells. He continued this work as a
Newton International Fellow at the University of Cambridge. At
Strankslab he is working on tandem solar cells. Started February 2020.

Ganbaa’s research has focused on the development of a novel X-ray detector for early-stage cancer detection. He also works on optoelectronic device fabrication including perovskite solar cells, photodetectors, light-emitting diodes and lasers. He received his BSc in Chemical Engineering from National University of Mongolia and MEng in Nanoscience and Nanoengineering from New Mongol Institute of Technology. He received his PhD in chemical engineering from Kyushu University in Japan.

Javad Shamsi Szymon Zelewski
 

Javad received his Ph.D. in NanoChemistry from Italian Institute of Technology in 2018, where he worked on colloidal synthesis of lead halide perovskite nanocrystals for optoelectronic applications under the advisement of Prof. Liberato Manna. He is now continuing as a postdoc to pursue his passion for the fundamental research in quantum confined perovskite nanocrystals at the University of Cambridge. Started June 2018.

Szymon obtained his MSc and PhD in physics from Wroclaw University of Science and Technology, Poland, where he studied fundamental electronic and optical properties of 2D materials and other low-dimensional semiconductor structures. As a postdoctoral fellow he expands his research interests to investigate electronic disorder and nonradiative recombination effects in perovskite materials using photothermal experiments. Started September 2021.
