Research in our lab lies at the interface of electrochemistry, solid-state physics, material chemistry and advanced spectroscopy. The overarching theme of our work is to understand and control the structure and dynamics of semiconductor/electrolyte interface for energy harvesting and storage.

 

Semiconductor electrochemistry today plays a vital role in several important technological processes, ranging from energy scavenging by photoelectrochemical solar cells to energy storage by Li-ion batteries.  Improvements in device performance require understanding the physics of semiconductor excitonic transitions and the chemistry of the interfacial processes.  Work in our lab is highly interdisciplinary in nature, and spans fundamental studies of interfacial phenomena, spectroscopic techniques that probe excited state transitions in ultrafast time scale­­­­, synthesis of nanostructures, and fabrication of photoelectrochemical solar cells, electrochromic smart windows and Li-ion batteries.  The various aspects of our work are shown above.
