Building 3, level 3 (seaside)


I am Rakesh Rosan Pradhan, born in Odisha, India. My inclination towards physics began during my bachelor’s degree. Under its excellent faculty and facilities, I got exposed to experimental and theoretical Physics. To pursue my research dreams, I joined the Indian Institute of Technology Jodhpur (IITJ), India for my Master of Science course in Physics. During this period, I attended an invited talk by prof. Udo (KAUST, Saudi Arabia), which influenced me to think about the fundamental research in material science using density functional theory. I visited KAUST as a VSRP fellow during the initial phase of the COVID pandemic. I liked the research environment and decided to continue my journey as a Ph.D. student. Currently, I am working in Kaust Solar Centre with Prof Stefaan De Wolf on single-junction perovskite Solar cell sing blade coating and slot-die methods.

Research Interests

Keywords: Perovskites single junction solar cell, interface study, density functional theory, Blade coating, Slot-die coating

I study solar cell-based different interface phenomena with the computational method and try to implement the idea by fabricating and characterizing devices. Using Density Functional Theory, I inspect suitable properties of organic-inorganic perovskites for photovoltaic applications. It involves compositional engineering to tune material properties, employing passivation to eliminate various defects, and studying charge carrier transport and recombination in the solar cell. Then I use theoretically screened suitable materials in fabricating single junction solar cells by blade coating and slot-die method.
