Welcome To Dr. Tufan Ghosh Research Group

Dr. Tufan Ghosh Research Group at the Department of Chemistry, VIT-AP University focuses on understanding fundamental processes in lead halide-based perovskite photovoltaics. We synthesize new perovskite materials, and unfold photoexcited carrier and lattice relaxation dynamics using a range of advanced spectroscopic techniques. For more details about our research, please visit the Research page and if you are interested in our research, or visit Join Us page. 

Two Ph.D. positions are available at our research group: A research fellowship will be given to the eligible candidates. For more details, please click here for more information.
