Meysam Pazoki, Associate Professor. is a researcher with the Department of Engineering Sciences : solid state physics , Uppsala University. Dr. Pazoki received his docent in solid state physics from Uppsala University in 2019. His areas of interest include (T)DFT calculation of semiconductors for Photovoltaic devices and CO2 reduction applications; dye sensitized and Perovskite solar cells, UV Photodetectors; as well as device characterization methods including: Impedance spectroscopy, Electrochemical methods, Small photovoltage/current transients; Material Characterization: Laser Spectroscopy, Stark spectroscopy Prof. Anders Hagfeldt is regarded as one of the world's leading researchers into dye-sensitised solar cells. Using various methods and new nanostructured materials, he and his research team have succeeded in substantially improving the efficiency of these third-generation solar cells. Anders Hagfeldt is regarded as a highly creative scientist who throughout his fundamental research never loses sight of the industrial application. He is the Head of the laboratory at the Laboratory of Photomolecular Science, Ecole Polytechnique Federale De Lausanne, a leading institution in the field of solar cell research.Prof. Hagfeldt is the recipient of the Thuréus award” from Royal Society of Sciences and the Norblad-Ekstrand medal” from The Swedish Chemical Society. Tomas Edvinsson is a professor in Solid State Physics at the Department of Engineering Sciences, Ångström Laboratory, Uppsala University, directing a research group working on low dimensional materials for solar cells (CIGS, DSSC, perovskites) and photocatalysis. He is the author of 100+ scientific publications and project leader for several national projects from the Swedish research council, the Swedish Energy Agency, and work package leader in a European H2020 project within solar fuels. He act as reviewer for several national (Swedish, Swiss, German, and Netherland research councils) and larger international grant organizations (ERC, DFG priority program, among others)
