High-Efficiency Multijunction Photovoltaics for Low-Cost Solar Electricity
Richard R. King, Spectrolab, Inc., A Boeing Company, USA |
 |
Biography: Dr. King is Principal Scientist and Boeing Technical Fellow responsible for photovoltaic cell R&D at Spectrolab, Inc. He received his Ph.D. degree in Electrical Engineering at Stanford University for his work on high-efficiency silicon back-contact solar cells and minority-carrier recombination at the doped Si/SiO2 interface. Dr. King's research on photovoltaics over the last 20 years includes work on GaInP/GaInAs/Ge triple-junction cells, 4-, 5-, and 6-junction solar cells, and metamorphic III-V materials lattice-mismatched to the growth substrate. Dr. King has led Spectrolab's development of III-V multijunction cell structures resulting in new heights in solar cell efficiencies, recognized with R&D 100 awards in 2001 and 2007, and a Scientific American 50 award in 2002. In 2006, this work led to a record 40.7%-efficient triple-junction terrestrial concentrator cell, the highest solar conversion efficiency yet measured for any type of photovoltaic device under standard spectral conditions, and the first solar cell to reach over 40% efficiency. Dr. King was inducted into the Space Technology Hall of Fame in 2004, and has 11 patents and over 90 publications on photovoltaics and semiconductor device physics.

Abstract: Multijunction solar cells divide the solar spectrum into smaller slices, delivering experimental efficiencies over 40%, and enabling theoretical efficiency over 60%. These high efficiency cells are a powerful lever to reduce the cost of concentrator photovoltaic systems, opening the way for plentiful solar-generated electricity. |

GaN-Based Solid State Lighting
Shuji Nakamura, University of California - Santa Barbara, USA |
 |
Biography: Shuji Nakamura was born on May 22, 1954 in Ehime , Japan . He obtained B.E., M.S., and Ph.D. degrees in Electrical Engineering from the University of Tokushima, Japan in 1977, 1979, and 1994, respectively. He joined Nichia Chemical Industries Ltd in 1979. In 1988, he spent a year at the University of Florida as a visiting research associate. In 1989 he started the research of blue LEDs using group-III nitride materials. In 1993 and 1995 he developed the first group-III nitride-based blue/green LEDs. He also developed the first group-III nitride-based violet laser diodes (LDs) in 1995. He has received a number of awards, including: the Nishina Memorial Award (1996), MRS Medal Award (1997), IEE E Jack A. Morton Award, the British Rank Prize (1998) and Benjamin Franklin Medal Award (2002). He was elected as the member of the US National Academy of Engineering (NAE) in 2003. Also, he received the Millennium Technology Prize in 2006. Since 2000, he is a professor of Materials Department of University of California Santa Barbara . He holds more than 100 patents and has published more than 350 papers in this field. |
Abstract: High-efficient violet, blue, green and yellow LEDs, and violet laser diodes were grown on Polar/nonpolar/semipolar GaN bulk substrates. In order to make a real GaN bulk crystal, we have developed the ammonothermal method. |

Rodney S. Tucker, University of Melboune, Australia |
 |
Biography: Rod Tucker is a Laureate Professor at the University of Melbourne and Research Director of the Australian Research Council Special Research Centre for Ultra-Broadband Information Networks. He has held positions at the University of California, Berkeley, Cornell University, Plessey Research (Caswell), AT&T Bell Laboratories, Hewlett Packard Laboratories and Agilent Technologies. He is a Fellow of the Australian Academy of Science, the Australian Academy of Technological Sciences and Engineering, the IEEE, and the OSA. He was awarded the Australia Prize in 1977 for his contributions to telecommunications and the IEEE LEOS Aron Kressel Award in 2007 for his contributions to semiconductor optoelectronics. |
Abstract: We quantify the greenhouse impact of the transmission and switching equipment that supports the global telecommunications network. Projections of the growth of energy consumption are presented and approaches to minimizing energy consumption are outlined. |

Opportunities in Quantum Information Science and Technology
Matthew S. Goodman, DARPA/DSO, USA |
 |
Biography: Dr. Goodman is a program manager for the Defense Sciences Office at the Defense Advanced Research Projects Agency (DARPA). Prior to that, he served as a Chief Scientist and Telcordia Fellow at Telcordia Technologies in New Jersey and Maryland . Dr. Goodman has been the Principal Investigator on a number of quantum information programs, including fiber-based quantum key distribution research and programs evaluating the performance of quantum data encryption and their associated optical technologies. He has worked extensively in multiwavelength network architectures, technologies, and their simulation. His research interests include novel optoelectronic devices and intelligent electronics, and optoelectronics and some multidisciplinary complex systems. Dr. Goodman received his undergraduate degree at Indiana University (B.Sc., cum Laude, Physics), and his master's degree and doctorate in Physics from the Johns Hopkins University. Prior to joining Telcordia Technologies, he served as a faculty member in the Department of Physics at Harvard University working in high energy particle physics for nearly a decade. Dr. Goodman has numerous papers and presentations, and has 4 U.S. Patents on multiwavelength networks. He has won a number of awards for his work including the Harvard Thomas T. Hoopes III Undergraduate Teaching Award, the Bellcore President's Award, an R&D 100 Award, the Telcordia CEO Award, and in 2002 was made a Telcordia Fellow. He is a Senior Member of the IEEE LEOS.
