Ultrafast Photophysics

At the GeM Laboratory’s Ultrafast Photophysics Group​​, researchers focus on unraveling ultrafast photophysical processes in advanced optoelectronic materials and devices, with an emphasis on light-matter interactions, charge dynamics, and energy conversion mechanisms. Their work bridges ultrafast spectroscopy, material engineering, and device physics to address fundamental challenges in fields such as solar energy conversion, photodetection, and environmental remediation. ​​Their core research directions encompass organic solar cells (OSCs), organic photodetectors (OPDs), and photocatalysis & environmental remediation.​ Research methodologies including:

• Femtosecond transient absorption spectroscopy
• Femtosecond transient fluorescence spectroscopy
• Femtosecond transient stimulated Raman (FSRS)
• TPV/TPC/CE techniques
• DFT, MD, Drift-Diffusion simulations
