年卷期:Joseph S. Manser was born in Youngstown, Ohio, in 1989. He received his B.Sc. in 2011 from Catawba College and is currently pursuing a Ph.D. at the University of Notre Dame. His research focuses on the fundamental photophysics and structure–property relationships that underlie operation of next-generation optoelectronic devices, including perovskite solar cells, and the application of those devices for electricity and solar fuels generation.Makhsud I. Saidaminov was born in Tajikistan in 1988. He received his Ph.D. in 2013 from Lomonosov Moscow State University, Russia. He is currently a Postdoctoral Fellow in the Physical Sciences and Engineering division at KAUST, Saudi Arabia. His research focuses on the engineering of materials, particularly hybrid perovskite single crystals, and their integration into optoelectronic devices.Jeffrey A. Christians was born in Grand Rapids, Michigan, in 1988. He received his B.S.E. in 2010 from Calvin College and his Ph.D. from the University of Notre Dame in 2015. He is currently a postdoctoral researcher in the Chemistry & Nanoscience Center at the National Renewable Energy Laboratory in Golden, CO. Here his research focuses on understanding the relationship between the structure and key optoelectronic properties of hybrid organic–inorganic perovskites.Osman M. Bakr was born in Saudi Arabia in 1981. He holds a B.Sc. in Materials Science and Engineering from MIT (2003) as well as a M.S. and Ph.D. in Applied Physics from Harvard University (2009). He is currently an Associate Professor of Materials Science and Engineering, SABIC Presidential Career Development Chair, at KAUST, Saudi Arabia. His research group focuses on the study of hybrid organic–inorganic nanoparticles and materials; particularly advancing their synthesis and self-assembly for applications in photovoltaics and optoelectronics.Prashant V. Kamat is the Rev. John A. Zahm, C.S.C., Professor of Science at the University of Notre Dame. He earned his Ph.D. in Physical Chemistry from Bombay University in 1979 and was a postdoctoral researcher at Boston University and the University of Texas at Austin before joining Notre Dame.
