Obtained his PhD degree at NWPU Xi’an China (2021). He worked in several projects during his doctoral research focusing two-dimensional electron gas. He has good grasp in exploring structural, optical, and magnetic properties of materials. Presently he is working on the studies of eutectic based photochemical devices as post-doctoral researcher.
Is currently a PhD student in the Solar Energy Conversion group. She has done her bachelor’s studies in physical sciences in Delhi University, India and received her M.Sc. degree in chemistry in Siegen University, Germany with a thesis focused on Thermochemical cycling of monoclinic CaZn2(PO4)2 · 2H2O on a technical scale.
Solar Energy Conversion group is responsible for the materials development in the direction of solar energy conversion applications. Recent achievements in solar energy engineering focus on composite and multi-layer materials exhibiting highly optically-nonlinear properties which increase light conversion efficiency. The research goal of the group will be development of novel methods for obtaining materials in areas of photovoltaics and photoelectrochemistry. Up to now, we have successfully demonstrated utilization of eutectic composites for water splitting and generation of hydrogen, which is one of promising renewable energy sources. The main advantages of hydrogen fuel are: high energy conversion efficiency, carbon free emission; the ability to be produced from renewable energy sources; and its ability to serve as a storage medium. We have also shown interesting results on increasing weak up-conversion process with plasmonics in a eutectic composite. Up-conversion and plasmonics are on the roadmap of photovoltaic technology, which is why this is another essential direction for the group to work on. According to the research program, we will work on developing thin layers of eutectic composites which can open up several unique opportunities: (i) manufacturing of hybrid materials, including complex oxides and oxide-non-oxide composite semiconductors with improved photoelectrochemical performance, (ii) better understanding of the behaviour of highly crystalline semiconductor hetero-junctions formed in nanoscale multicomponent systems, and (iii) significant impact on areas beyond photo-electrochemistry such as nanotechnology, sensing, chemistry, and photovoltaics. The group will also work on adopting plasmonic nanostructures and metamaterials, which would exhibit enhanced electromagnetic phenomena.
