Research Overview

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 investigate the charge transport in the semiconducting materials to develop efficient photocatalysts for the treatment of wastewater. We develop nanostructured 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. Various questions remain unanswered with regards to understanding of these materials. Our research on perovskite solar cell is to understand film formation of the perovskite materials, composition/interface engineering and in-house synthesis of new hole-transporting materials. Emphasis is to understand degradation of devices through measuring their performance under various stress conditions.
