Richard R. King
Dr. King received his B.S. in Physics, with Distinction, with Departmental Honors in 1985 (member Phi Beta Kappa), and M.S. and Ph.D. in Electrical Engineering in 1987 and 1990, respectively, all from Stanford University. His dissertation research concerned high-efficiency, single-crystal silicon solar cells, and minority-carrier recombination at the doped Si/SiO2 interface. At Spectrolab, he is principal investigator of Spectrolab’s Dual-Use Science & Technology (DUS&T) program to develop new high-efficiency semiconductor materials and multijunction solar cells, and is principal investigator in charge of high-efficiency terrestrial concentrator cell development in Spectrolab's High Performance Photovoltaics (HiPerf PV) program from the National Renewable Energy Laboratory (NREL). Dr. King led Spectrolab's development of III-V multijunction cell structures resulting in new heights in solar cell efficiencies, recognized with an R&D 100 award in 2001, and a Scientific American 50 award in 2002. This work has recently led to a new record 40.7%-efficient triple-junction terrestrial concentrator cell, the highest solar conversion efficiency yet achieved for any type of photovoltaic device, 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 10 patents and over 80 publications on photovoltaics and device physics. |
Dr. Richard R. King is a Boeing Technical Fellow, and Principal Scientist responsible for Photovoltaic Cell R&D at Spectrolab, Inc. His research on photovoltaics over the last 20 years includes studies of metamorphic III-V materials and devices lattice-mismatched to the growth substrate, high-efficiency multijunction solar cell architectures, such as GaInP/GaInAs/Ge triple-junction cells and 4-, 5-, and 6-junction cells, group-III sublattice ordering in GaInP, minority-carrier recombination at heterointerfaces in III-V semiconductor devices, dilute nitride materials and devices such as ~1-eV GaInNAs solar cells, and multijunction solar cells formed by wafer bonding dissimilar materials such as III-V semiconductors and silicon.
