On July 4, 2025, the Institute of Applied Physics and Materials Engineering (IAPME) welcomed Prof. Mingzhen Liu (劉明偵) from the University of Electronic Science and Technology of China (UESTC) for a cutting-edge seminar titled “Regulating Carrier Transport toward Highly Efficient Perovskite-based Tandem Solar Cells” Hosted by Prof. Guichuan Xing, the event drew the attention and attendance of over 30 faculty members, researchers, and students.
Prof. Liu, an internationally recognized expert in perovskite photovoltaics and Royal Society of Chemistry Fellow, unveiled breakthrough strategies for achieving >34% certified efficiency in perovskite/silicon tandem devices. She detailed molecular-level innovations in charge transport layer design and conformal perovskite crystallization on textured silicon substrates—critical for industrial scalability. Her talk emphasized overcoming interfacial charge transfer limitations, a major bottleneck in commercializing tandem technology.
Following the presentation, attendees engaged in a dynamic Q&A session, with heated exchanges on carrier dynamics optimization, triple-junction cell architectures, and flexible tandem applications. Doctoral candidates and IAPME’s device engineering group particularly explored synergies with ongoing projects in perovskite light-emitting devices and vacuum-evaporated micro-displays.
This seminar strengthened academic ties with UESTC while spotlighting IAPME’s leadership in advanced energy materials. Prof. Liu’s insights will inform collaborative R&D pathways for high-efficiency photovoltaics, aligning with Macau’s green technology initiatives.
