The power conversion efficiency of single-junction solar cells is limited by transmission and thermalization losses. (Sensitized) triplet fusion and singlet fission has emerged as promising strategies to circumvent these efficiency losses in solar cells. Some major challenges remain, including; development of (near-)infrared absorbing sensitizer materials for triplet fusion and infrared emitter materials for singlet fission, improved organic materials for singlet fission and triplet fusion, fundamental understanding of excitonic conversion processes, energy migration, and energy transfer across hybrid interfaces, as well as device integration. The symposium will bring together experts in singlet fission and triplet fusion to discuss fundamental understanding of the excitonic conversion processes and development of new materials towards solar energy applications.

Seiichiro Izawa is an associate professor in Tokyo Institute of Technology in Japan, since 2023. He received his Ph.D. from Department of Applied Chemistry in the University of Tokyo in 2015 and worked at RIKEN in Japan and University of California, Santa Barbara as a postdoctoral fellow, and Institute for Molecular Science in Japan as an assistant professor. His research interests are optoelectronic properties at organic semiconductor interface for efficient organic electronics devices such as photovoltaics and light-emitting diodes.
From 2019, A.M. serves as Associate Professor in Condensed Matter Physics at Department of Materials Science. His research is focused on the development of advanced hybrid functional nanomaterials for applications in photonics and theranostics in collaboration with several national and international universities and research institutes. He started his research by working on hybrid organic/inorganic light NIR emitters based on lanthanides ions and photonic crystals for lighting and telecom, in the framework of several national and international project and networks. The topic of the current research is the design and study of advanced materials and nanostructured materials for photon managing and scintillation applications. The experimental activity is centered on CW and ultrafast TRPL photoluminescence spectroscopy, transient absorption spectroscopy, confocal imaging, IR and FT-IR spectroscopy to tackle both fundamental and applicative aspects aimed at the development of materials to implemented real-world technologies.
