Recently, Associate Professor Chen Xihan from the Department of Mechanical and Energy Engineering at the Southern University of Science and Technology visited the Institute and engaged in academic exchanges with faculty members and students. The exchange session was chaired by Professor Ling Li of the Institute.

Dr Chen Xihan provided a detailed explanation of the mechanisms of energy conversion processes in various materials within the development of efficient and stable solar energy conversion systems. He pointed out that the dynamic mechanisms at the interfaces of energy-conversion materials are among the key factors determining the efficiency and stability of energy conversion. By employing pump–probe techniques, one can directly characterize the complete process of material transformation and energy transfer during surface–interface energy conversion. From the perspectives of in situ ultrafast absorption spectroscopy, in situ ultrafast reflection spectroscopy, and ultrafast polarization spectroscopy, he revealed the photophysical properties of materials, thereby offering fundamental theoretical guidance for the design of new materials, the development of novel devices, and the optimization of existing energy conversion systems.

Attending faculty members and students engaged in discussions with Dr Chen Xihan based on their respective research fields.
