Dr Sonia Ruiz Raga
Postdoctoral researcher, Research Fellow
Dr. Sonia R. Raga (B.Sc. Chem. Eng., 2010), obtained her M.Sc. (2011) and Ph.D. (2013) on Nanoscience and Nanotechnology at the Physics Department of the Universitat Jaume I (Spain). Her Ph.D focused on the device fabrication and characterization of organic and dye-sensitized Solar Cells, specialising on frequency-resolved electrochemical measurements. Dr. Raga completed a postdoctoral position at the Okinawa Institute of Science and Technology (OIST, Japan), continuing her research on perovskite solar cells (PSC). Her main work was to develop new synthesis methods for the optimization of perovskite and selective contact layers and understanding the device physics of the device. Her pioneering work on the gas-assisted perovskite film deposition (patent filed) got awarded funds from the OIST Proof of Concept Program (PoC), where she helped leading the Project from Feb 2017. In October 2017, she continued her research at Monash University (Australia), joining the Australian Centre of Excellence in Exciton Science (ACEx). Within the center she specialised on device electrical characterisation. Other responsibilities include conference and workshop organization and chair, undergraduate final year project coordination and Ph.D. students mentoring and supervision. In 2019, she completed the CSIRO ON Program, gaining skills on networking towards applying and maximising the impact of the research innovations. Dr. Raga has a total of 38 publications, with over 2500 citations (h-index 25), 5 patent applications and 1 book chapter. She is peer reviewer for 22 scientific journals, reviewer for a Ph.D. thesis and a Ph.D. proposal, and is part of the editorial board of Frontiers in Energy Research: Solar Energy.
Dr. Raga has a strong motivation on contributing to the zero-emissions global Energy Transition through the development of next generation photovoltaics. Her research interests are the identification of the physical mechanisms limiting the performance and stability of these devices such as electronic transport, charge transfer and the effects of the ionic-electronic coupled conduction of hybrid perovskite materials, as well as overcoming these limitations through tailored modifications of the materials and interfaces.
