Green synthesis of nanomaterials
High dielectric constant materials
Hybrid perovskite solar cells
Electrospinning of functional polymers and nanocomposites for photocatalysis and energy storage applications
Energy and water are two world’s major challenges with increasing population. Our research focuses on the development of multifunctional hybrid nanostructures for energy and environmental applications. Our thrust is on synthesizing nanomaterials utilizing a greener route. We look into the charge transport in the semiconducting materials in order to develop efficient photocatalysts for the treatment of wastewater. We develop nano-structured metal oxides using simple and cost effective methods and look into their utilization as electrode materials for high energy/power density energy storage applications. Perovskite materials are arising as a new generation of solution processable inorganic-organic hybrid photovoltaic materials. Our research on perovskite solar cell involves in: Film morphology control for improving device efficiency and reproducibility; Design new materials for improving device performance and stability; and Understanding the fundamental device physics of perovskite solar cells.
