Critical Interfaces in Emerging Thin Film Photovoltaic Technologies: From Basic Science to Policy and Economic Issues
The widespread adoption of photovoltaic energy conversion technologies, especially in the U.S., is determined by a combination of scientific challenges, economics and energy policy. The Department of Energy has set as a goal the creation of PV platforms that efficiently produce electrical power at a cost of well under $1 per watt installed, which creates breathtaking technical challenges to overcome. This talk will focus on some of the scientific/technical challenges we face in creating "scalable" (solar cells that can be printed at 100's of meters per day), where materials costs are extremely low, accompanied by low (but increasing) efficiencies. We will review studies underway that allow us to understand and control the critical interfaces in these PV platforms, that currently limit both efficiency an lifetime. We view all of this basic science in the context of a constantly changing political and economic environment for PV-based electricity, and an exciting future for these new PV technologies.
Neal R. Armstrong is Professor of Chemistry/Biochemistry and Optical Sciences at the University of Arizona, and has been on the faculty here since 1978. His research interests have focused on the interface science underpinning the development of new molecular electronic technologies, and new energy conversion platforms, and chemical sensors. He has authored/co-authored over 300 scientific publications, and produced ca. 50 Ph.D. and M.S./M.A. students in his career, along with a host of undergraduate researchers, postdocs and visiting scientists from around the world. He is currently a member of the Galileo Circle in the College of Science at UA, and has been recently selected as Regents Professor.

Dynamic Spectroscopy – a Critical Tool for Developing Artificial Photosynthesis
For the development of an efficient artificial photosystem that converts carbon dioxide and water to a fuel in a nanostructured inorganic unit, transient optical and infrared spectroscopy of charge transport and catalytic processes provide key insights that guide materials designs.
Heinz Frei (Dr.sc. ETH Zurich) is a Senior Scientist at Lawrence Berkeley National Laboratory in Berkeley, California. His main research is in on the development of photocatalytic assemblies in nanostructured materials for the synthesis of everyday chemicals and fuels by visible and near infrared light, with emphasis on understanding elementary chemical processes by transient optical and infrared spectroscopy. He leads the Interface Project of the Joint Center for Artificial Photosynthesis (JCAP).

Invention and Innovation – Key to keeping Photovoltaic R&D in the United States
The photovoltaic industry, like other technology-based industries, has undergone a massive migration out of the US. To ensure participation of US-based manufacturing companies in this important technology (and US-based R&D), we need innovation, not just invention.
Doug received a doctorate in 1982 in applied physics while a student employee at LLNL. He joined Corning for a 27 year career in a number of roles including research scientist, R&D manager, Technology Vice-President and business unit leader serving optical and glass product businesses. He joined the U.S. Department of Energy in 2011 as a Technology Manager in the SunShot Initiative. Doug is the author of over 20 articles in refereed technical journals and three book chapters. He holds 17 U.S. patents. He is a Fellow of the Optical Society of America and on the OSA Board of Directors.

The Past, Present and Future of Freeform Optics
Freeform optical surfaces are emerging as a path to truly three-dimensional optical designs. In this talk I will provide a short historical context to this emergence and discuss the challenges as well as the rapidly emerging knowledge that spans from the mathematics of freeform surfaces to the implementation of freeform optical systems.
Jannick Rolland is the Brian J. Thompson Professor of Optical Engineering at the Institute of Optics at the University of Rochester (UofR), where she also serves as Associate Director of the R.E. Hopkins Center for Optical Design and Engineering and directs the Optical Diagnostics and Applications Laboratory (ODALab). She also holds an appointment in the Department of Biomedical Engineering and in the Center for Visual Science at UofR. Professor Rolland earned an Optical Engineering Diploma from the Institut d'Optique, France, and an MS and PhD in Optical Science from the College of Optical Sciences at the University of Arizona. Upon completing her degree, Dr. Rolland joined the Department of Computer Science at the University of North Carolina at Chapel Hill (UNC-CH) as a postdoctoral fellow, where she focused on learning vision and computer graphics while designing the first off-axis stereoscopic head-worn displays for medical visualization. She was appointed to lead the Vision Research Group for Medical Displays at UNC-CH (1992-96), where the team investigated the impact of the shape of objects on medical tasks. In 1996, she joined CREOL, the College of Optics and Photonics at the University of Central Florida, where she founded the ODALab.
