This symposium invites contributions on emerging photon multiplication and photon conversion processes and their applications in next-generation optoelectronic and energy-harvesting technologies. Advanced photophysical mechanisms such as singlet fission, quantum cutting, and upconversion are attracting increasing attention as promising strategies to enhance light-matter interactions and potentially surpass conventional efficiency limits in optoelectronic devices. Recent progress has been achieved across a variety of material platforms, including organic semiconductors, metal-halide perovskites, nanocrystals, rare-earth-based systems, and hybrid materials. This symposium aims to bring together researchers investigating the fundamental photophysics, spectroscopy, and materials engineering underlying these processes, as well as their integration into functional devices. Contributions addressing the implementation of photon multiplication strategies in applications such as photovoltaics, photodetectors, light-emitting devices, and other emerging applications are particularly encouraged. By connecting currently fragmented communities working on related photon conversion mechanisms across different materials and applications, this symposium seeks to stimulate interdisciplinary discussions and accelerate the development of innovative photon management strategies for future technologies.

Antoine Kahn is a professor of Electrical Engineering at Princeton University. He received his PhD in Electrical Engineering and Computer Science from Princeton University in 1978. His current research interests include the structural, electronic and chemical properties of surfaces and interfaces of intrinsic and doped organic and hybrid semiconductor films. Recent work includes (i) the physics and applications of n- and p-type molecular dopants in organic thin films, (ii) organic/organic heterojunctions, (iii) transition metal oxides in organic electronics, and (iv) organo-metal perovskites. Kahn has co-authored over 380 refereed regular and review articles. He was the recipient of a Presidential Young Investigator Award (1984-85), of the Joseph Meyerhoff Visiting Professorship (2002) and of the Weston Visiting Professorship (2009-12), Weizmann Institute of Science, Israel. He is a Fellow of the AVS (1999) and APS (2002). He was listed among the “World’s Most Influential Scientific Minds”, Thomson Reuters 2014.
Xiaogang LiuSean T. Roberts received his BS in Chemistry from the University of California Los Angeles in 2003 and his PhD in Physical Chemistry from the Massachusetts Institute in Technology in 2010 for work using multidimensional infrared spectroscopy to study proton transport in liquid water with Andrei Tokmakoff. In 2010, Sean was awarded an NSF ACC-F postdoctoral fellowship and undertook a position at the University of Southern California where he worked in the groups of Stephen Bradforth and Alexander Benderskii on collaborative projects organized by the Center for Energy Nanoscience, a DOE supported Energy Frontier Research Center. In 2014, Sean started his independent career at the University of Texas at Austin where he leads a research group that uses and develops ultrafast spectroscopic techniques to understand how the mesoscopic ordering of semiconductor nanomaterials impacts their ability to manipulate energy and transport charge. Sean is a recipient of the NSF CAREER award, was named a Cottrell Scholar in 2018, and has lead projects funded by the W. M. Keck Foundation, Air Force Office of Scientific Research, Robert T. Welch Foundation, and the ACS Petroleum Research Fund. Sean has also won numerous teaching awards and currently leads an ACS and NSF-funded education and research program, GReen Energy At Texas (GREAT), that works with community colleges to increase student retention and degree attainment in the physical sciences.
