Title: Optoelectronic Devices from Solution-Processed Methods
Abstract: Optoelectronic devices fabricated through solution-processed methods, such as Organic Light Emitting Diodes (OLEDs), Organic Photovoltaics (OPVs), and perovskite solar cells (PeSCs), consist of active thin films (including polymeric and organic-inorganic perovskite-type materials) deposited between two electrodes—one being a transparent electrode, typically serving as the anode, and the other a metallic cathode.
Over the past decade, solution-processing technology for optoelectronic device fabrication has made tremendous advancements, leading to the commercial availability of such devices. However, their efficiency and stability depend not only on the properties of the active materials but also on their interfaces with the electrodes.
The incorporation of intermediate layers that modify the electrode/active film layer interface is essential for achieving more efficient charge carrier exchange between the electrodes and the active film layers. Transition metal oxides, polyoxometalate compounds, and small-molecule thin films have been widely utilized in recent years as charge injection/extraction layers between the electrodes and active layers, enhancing both the performance and stability of these devices.

Dr. Anastasia Soultati currently works as postdoctoral researcher on interface engineering of organic optoelectronic devices at the National Center of Scientific Research “Demokritos” (NCSR D) in Athens, Greece. During 2021 and 2016 worked as adjunct assistant professor in the Department of Materials Science in the University of Patras and the Department of Electrical and Electronics Engineering of Unoversity of Wet Attica. She has also earned two IKY fellowships for postdoctoral research.
She received a degree in Physics and a M.Sc. in Microelectronics from the University of Athens in 2009 and 2012, respectively, and her Ph.D. from the Chemical Engineering Department of National Technical University of Athens in 2016. She then worked as postdoctoral associate on molecular materials technology for microelectronic applications at NCSR “Demokritos”. She was also worked as Graduated Research Assistant for the Research Funding Program: Aristeia II - “Implementing advanced interfacial engineering strategies for highly efficient hybrid solar cells” (IMAGINE-HYSOL) at the Department of Physics, University of Patras, Greece and she earned a fellowship as a Phd candidate in the framework of the Research Funding Program Thales-PHOTOPOLIS at the Department of Materials Science, University of Patras, Greece.
In 2012, she participated as Graduated Research Assistant for the Research Funding Program IKYDA - 3D-Nanostructured electrodes and advanced interface technology for integration of transparent conductive oxides in organic electronics, Greek Scholarship Foundation-German Academic Exchange Service. Her research focuses on the area of interface engineering in Organic and Perovskite Optoelectronic Devices Photovoltaics, and her main scientific interests include the fabrication and characterization of transition metal oxide thin films used in optoelectronic devices.
