QTuA1 • 08:00 TutorialSolar Energy Applications of Plasmonics, Harry Atwater, Caltech, USA. Plasmonics has provided optics researchers new means to control dispersion and light localization at nanoscale dimensions. Now plasmonic design approaches are yielding light trapping structures for improved efficiency in thin solar cells and structures for solar fuel generation.

Harry Atwater is currently Howard Hughes Professor and Professor of Applied Physics and Materials Science at the California Institute of Technology. His research interests center around two interwoven research themes: photovoltaics and solar energy; and plasmonics and optical metamaterials. Atwater and his group have been active in photovoltaics research for more than 20 years. Recently they have created new photovol-taic devices, including the silicon wire array solar cell, and layer-transferred fabrication approaches to III-V semiconductor III-V and multijunction cells, as well as making advances in plasmonic light absorber structures for III-V compound and silicon thin films. He is an early pioneer in surface plasmon photonics; he gave the name to the field of plasmonics in 2001. He has authored or co-authored over 200 publications, and his group’s developments in the solar and plasmonics field have been featured in Scientific American and in research papers in Science, Nature Materials, Nature Photonics and Advanced Materials.

Atwater received his S.B. (1981), S.M. (1983), and Ph.D. (1987) in Electrical Engineering from the Massachusetts Institute of Technology. He cur-rently serves as Director of the DOE Energy Fron-tier Research Center on Light-Matter Interactions in Solar Energy Conversion (http://lmi.caltech.edu ) and was recently named Director of the Resnick Institute for Science, Energy and Sustain-ability, http://resnick.caltech.edu/ , Caltech’s largest endowed research program focused on energy. Atwater is founder and chief technical advisor for Alta Devices, a venture-backed company in Santa Clara, CA developing a transformational high efficiency/low cost photovoltaics technology, and Aonex Corporation, a compound semiconductor materials company. He has also served an editorial board member for Surface Review and Letters. Professor Atwater has consulted extensively for
