Richard King - Editor III-V Solar Cells and Concentrators
Prof. Richard R. King received his Ph.D. and M.S. from Stanford University in Electrical Engineering, and his B.S in Physics, also from Stanford. He is currently Professor of Electrical, Computer, and Energy Engineering at Arizona State University. Over the past 30 years, his research on photovoltaics has explored high-efficiency solar cells in a number of semiconductor materials systems, from silicon, to the GaInP, GaInAs, and germanium subcells in III-V multijunction cells. Dr. King and his colleagues have been especially interested in the materials science and device physics of III-V multijunction solar cells for concentrator photovoltaics (CPV), and in the defect physics of low-cost semiconductors for high-efficiency, flat-plate multijunction cells. In his Ph.D. research at Stanford University, Dr. King worked to develop high-efficiency one-sun back-contact silicon solar cells, and on characterization of minority-carrier recombination at the doped Si/SiO2 interface for high-efficiency silicon solar cell design. Since then his research has contributed to understanding of metamorphic III-V materials lattice-mismatched to the growth substrate; group-III sublattice ordering in GaInP; minority-carrier recombination at III-V heterointerfaces; high-transparency tunnel junctions; dilute nitride materials such as ~1-eV GaInNAs and GaNAsSb for solar cells; and high-efficiency multijunction solar cells with 3 to 6 junctions. Dr. King led Spectrolab's development of high-efficiency III-V multijunction concentrator solar cells, 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 metamorphic 3-junction terrestrial concentrator cell, the first solar cell to reach over 40% efficiency. At Arizona State University, Dr. King's research group investigates recombination at defects and interfaces in low-cost polycrystalline solar cell materials, and integrating them into tandem solar cells with silicon to realize the high-efficiency multijunction cell structure in a cost-effective flat-plate format. As part of a strong interest in furthering public and scientific awareness of photovoltaics, Dr. King has helped organize a number of international conferences, serving as Program Chair for the 4th International Conference on Solar Concentrators (ICSC) in 2007, and the 35th IEEE Photovoltaic Specialists Conference (PVSC) in 2010, and he was General Chair for the 40th IEEE PVSC in Denver, Colorado, in 2014.

Ronald A. Sinton received his Ph.D in Applied Physics from Stanford University in 1987, following a B.S. from the University of Colorado in 1981. After a Research Associate position at Stanford, he was a founding member of SunPower Corp. before starting Sinton Instruments in 1992.
His early technical work at Stanford University included the demonstration of 28%-efficient silicon concentrator solar cells, and work on the device physics of high-injection solar cells including detailed device modeling, measurements of Auger recombination and carrier mobilities, the development of advanced passivation and emitter technologies, test and measurement equipment for carrier lifetime and efficiency measurements, and studies of solar-cell efficiency vs. design and process complexity. This led to simplified solar cell designs with efficiency comparable to the best devices. At SunPower, these technologies were moved towards manufacturing feasibility and commercialization.
At Sinton Instruments, the focus shifted first to consulting on projects such as the development of a NASA solar-power aircraft that exceeded 29,600 m in altitude and innovations leading to novel test and measurement instruments. The company now specializes in carrier lifetime measurements on silicon bricks, ingots, and wafers, solar cell IV testers, and solar module testers. Many of the instruments that are now quite standard within the industry were developed at Sinton Instruments, including the QSSPC method for studying bulk lifetime and surface passivations in wafers (1995), the standard methods for bulk lifetime measurements in ingots and bricks (2004), the Suns-Voc technique (1995), as well as the constant-charge method for accurately measuring high-efficiency n-type solar cells and modules in production(2005). These tools are in use at over 300 institutions and production facilities worldwide. Data from Sinton carrier-lifetime testers has been presented or cited in over 1000 scientific publications, creating a de-facto standard for lifetime measurements in silicon and a lifetime of fruitful collaborations with scientists, labs, and companies worldwide. These lifetime-test methods were incorporated into a SEMI Standard PV-13. Each of these techniques is solidly based on silicon device physics principles, facilitating extensive characterization results for studying the device physics of surface passivations and bulk lifetime supporting the growth of the silicon solar cell industry.
Dr. Sinton has coauthored over 100 publications in solar cell device physics and technology, 7 patents, and has participated in program committees for 4 conference series and reviews for 5 journals.

Yang Yang holds a BS in Physics from the National Cheng-Kung University in Taiwan (1982), and he received his MS. and PhD in Physics and Applied Physics from the University of Massachusetts – Lowell in 1988 and 1992, respectively. Before he joined UCLA in 1997, he was a technical staff of UNIAX (now du Pont Display) in Santa Barbara from 1992-1996. Prof. Yang is now the Carol and Lawrence E. Tannas Jr. Endowed Chair Professor of Materials Science and Engineering at UCLA. He is a materials physicist with expertise in the fields of electronic organics, organic/inorganic interface engineering, and related devices, such as photovoltaic cells, LEDs, memory devices. His major contribution in the organic solar energy is in the understanding of polymer morphology and the influence on device performance; the invention of inverted organic solar cell, and inverted tandem solar cell; and photovoltaic polarizer for the LCDs. Together with Solarmer Energy Inc. (spun-off from UCLA) and Prof. Luping Yu of the University of Chicago, they have created several world record high efficiencies in organic solar cells. In addition to the organic solar cells, his group also heavily involved in the solution processible CIGS/CZTS solar cells. His group has achieved of ~11.2% PCE for the CISS solar cell via the hydrazine process.
Yang has received the following honors/awards: The Carol and Lawrence E. Tannas Jr. Endowed Chair in Engineering, July 2011; Top 11 Hot-Researchers in 2010, Science Watch (published by Thomas Reuters); Highest cited Paper in 2010, Advanced Functional Materials;
Highest cited Paper in 2008-2010, Journal of American Chemical Society (JACS); IEEE Photovoltaic Field Expert, 2009; Microelectronics Advanced Research Corporation Inventor Recognition Award, 2007; NSF Career Award: 1998; 3M Young Investigator Award, 1998.
He has published more than 240 peer-reviewed papers (including book chapters); 40 patents (filed or issued), and 120 invited talks. His H-Index is ~66 as September 2011.
Ahmed Faheem Zobaa (M’02-SM’04) received the B.Sc.(Hons.), M.Sc., and Ph.D. degrees in electrical power and machines from Cairo University, Giza, Egypt, in 1992, 1997, and 2002, respectively. From 2007 to 2010, he was a Senior Lecturer in renewable energy with the University of Exeter, Cornwall, U.K. He was also an Instructor from 1992 to 1997, a Teaching Assistant from 1997 to 2002, and an Assistant Professor from 2003 to April 2008 with the Department of Electrical Power and Machines and the Faculty of Engineering, Cairo University, where he has also been an Associate Professor since April 2008. Currently, he is also a Senior Lecturer in power systems with Brunel University, Uxbridge, U.K. His main areas of expertise are lighting applications, power quality, ( marine) renewable energy systems, grid integration, smart grids and energy management.
