Joseph J. Berry is a Senior Research Fellow at the National Renewable Energy Laboratory and Associate Professor of Physics a the University of Colorado Boulder  working on metal halide perovskite based materials and devices. His Ph.D. for work was on spin transport and physics in semiconductor heterostructures from Penn State University. His efforts at NREL emphasize relating basic interfacial properties to technologically relevant device level behaviors in traditional and novel semiconductor heterostructures including oxides, organics, and most recently hybrid metal halide semiconducting materials. He also leads the DOE SETO “Perovskite Enabled Tandems” Project at NREL and is a PI for the NREL lead Center for Hybrid OrganicInorganic Semiconductors for Energy (CHOISE), an Energy Frontier Research Center financed by the Office of Basic Energy Sciences. 

Hyun Suk Jung is an associate professor in school of advanced materials science & engineering at Sungkyunkwan university (SKKU). He received his BS, MS, and PhD degrees in materials science & engineering from Seoul National University (SNU), in 1997, 1999, and 2004, respectively. He joined Los Alamos National Laboratory (LANL) as a director’s postdoctoral fellow in 2005. He had worked for Kookmin University (KMU) since 2006 and joined SKKU in 2011. He published over 130 peer-reviewed papers regarding synthesis of inorganic nanomaterials and dye-sensitized solar cells. He presently researches perovskite solar cells and flexible solar cells.

Annamaria Petrozza received her PhD in Physics from the University of Cambridge (UK) in 2008 with a thesis on the study of optoelectronic processes at organic and hybrid semiconductors interfaces under the supervision of Dr. J.S. Kim and Prof Sir R.H. Friend. From July 2008 to December 2009 she worked as research scientist at the Sharp Laboratories of Europe, Ltd on the development of new market competitive solar cell technologies (Dye Sensitized Solar cells/Colloidal Quantum Dots Sensitized Solar cells). Since January 2010 she has a Team Leader position at the Center for Nano Science and Technology -IIT@POLIMI. She is in charge of the development of photovoltaic devices and their characterization by time-resolved and cw Photoinduced Absorption Spectroscopy, Time-resolved Photoluminescence and electrical measurements. Her research work mainly aims to shed light on interfacial optoelectronic mechanisms, which are fundamental for the optimization of operational processes, with the goal of improving device efficiency and stability.
