Research Interests

Our research interests focus on investigating device physics and photophysics of organic and organic-inorganic hybrid perovskite materials and structures. Such fundamental study can be useful design motif to realize high-performance and low-cost optoelectronic devices. We utilize ultrafast laser spectroscopy to understand carrier dynamics and synchrotron based X-ray techniques to characterize materials structure. Combining with the study on device physics, we seek to better understand basic physics, chemistry, and potential application of next-generation solar cells, light-emitting diodes, transistors, and lasers.
