The opto-electronics and spectroscopy research group is actively engaged in investigating various fundamental and applied aspects of materials related to Energy (such as solar cell, thermoelectrics), Planetary Interior (such as minerals) & human health (such as proteins & enzymes) using optical spectroscopic & other related methods. Dr. Sutanu Mangal is working to optimise the fifth-generation high efficiency CIGS,CZTS and lead-free environment friendly low-cost tin based solar cells using both simulation and experiments. Particularly, synthesis of lead based and lead-freetin-based perovskite materials, deposition of ZnO, CIGS, CZTS and Perovskite materials on a low-cost substrate,optimization of layers thickness, cell fabrication and testing. Dr. Gopal K. Pradhan investigates the thermal conductivity of low dimensional materials (such as nanowires) for thermoelectric applications using Raman spectroscopy. He also uses spectroscopic & diffraction methods at different thermodynamic (pressure & temperature) conditions to study phase transition in technologically relevant materials as well as minerals related to earth interiors. Dr. Jagnyaseni Tripathy uses fluorescence spectroscopic and microscopic techniques to understand the protein-peptide system. Her focus is developing new material for biological probes and therapeutics besides understanding physiological important small globular protein behavior.
