Rational Design of Semiconductor/ Composites for Energy and Environmental Applications

         Our aim is to design 'n' develop standardized synthetic protocols using day - to - day available chemicals from the laboratory to generate various semicoductor structures and predict their mechanism of formation. Semiconuctors are aimed to have superior transport and light harvesting abilities. Further we test our hypothesis by evaluating their photocatalytic and photovoltaic properties  either by semiconductor or dye sensitization. 
Some of our recent findings based on the designing various semiconductors and evaluating their photovoltaic / photocatalytic/ dye adsorption properties are as follows:
