On November 17th, 2023, Professor Chen Shi from the University of Macau was invited by Professor Tang Yuxin from the School of Petroleum and Chemical Engineering at Fuzhou University to visit and exchange ideas with the research group. During the visit, he delivered a wonderful academic report titled "Bottom Interface Engineering for High Performance Perovskite Optoelectronic Devices" at Room 101, Quangang Building South.
In recent years, perovskite optoelectronic devices have sparked great research interest. Among various improvement strategies, interface engineering is considered to have tremendous potential for optimizing device performance. While the upper interface has been extensively improved to passivate interfacial defects, induce charge transfer, and enhance moisture resistance, the research on the bottom interface has been relatively limited, necessitating the development of corresponding optimization methods.
In Professor Chen Shi's report, they elaborated on the use of three methods: dual ion passivation, graphene coverage, and substrate modification, successfully achieving effective bottom interface engineering to further improve the performance of photovoltaics, LEDs, and photodetectors. This study provides important references and guidance for optimizing the bottom interface.
Professor Chen Shi's report captivated the keen interest of the attendees, igniting their desire for exploration. The participants actively engaged in the discussion session, delving into in-depth exchanges with Professor Chen Shi regarding research in related fields. This exchange not only strengthened mutual understanding but also further promoted academic collaboration and the development of the discipline.
This exchange event provided a valuable academic platform for the faculty and students of Fuzhou University. Through the sharing and discussion of academic reports, it not only promoted interdisciplinary collaboration but also drove the sharing and innovation of research results. We believe that such exchanges and collaborations will further advance the development of the electrochemical energy storage field and lay a solid foundation for future research breakthroughs. We look forward to more academic exchange activities of this kind to promote close collaboration between the academic and industrial sectors and jointly advance the progress of science, technology, and societal development.
