Research expertise: High-efficiency silicon and III-V photovoltaics, solid-state device physics, recombination at semiconductor defects and interfaces, multijunction solar cells, thin-film compound semiconductor growth and characterization.

Research in Richard King’s group includes technologies for one-sun, flat-plate multijunction cells, defect tolerance at grain boundaries and other defects in perovskites and wide-bandgap CIGS-related materials, physics of recombination-benign defects, low-cost polycrystalline III-V solar cells, dilute nitride Ga(In)NAs(Sb), and integration of compound semiconductors with high-efficiency silicon solar cells.

Prior to joining ASU he was Principal Scientist and Technical Fellow at Spectrolab, Inc. His research on photovoltaics over the last 30 years has explored metamorphic III-V materials, high-lifetime back-contact silicon solar cells, dilute nitride GaInNAs(Sb), ordered and disordered (Al)GaInP, characterization of defects and recombination in compound semiconductors, high-transparency tunnel junctions and integration into high-efficiency multijunction solar cells with 3 to 6 junctions. In 2006, this work led to the first solar cell of any type to reach over 40% efficiency. King is the recipient of the 2010 William R. Cherry Award given by the IEEE for “outstanding contributions to photovoltaic science and technology,” and is a co-founding editor of the IEEE Journal of Photovoltaics.
