 RESEARCH OVERVIEW

Energy and water are two of the world's major challenges with an 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 regard to the understanding of these materials. Our research on perovskite solar cells is to understand film formation of the perovskite materials, composition/interface engineering, and in-house synthesis of new hole-transporting materials. The emphasis is to understand the degradation of devices through measuring their performance under various stress conditions. We also worked for green fuel energy produced by photoresponse water splitting.
