DESCRIPTION:Prof. Dr. Randy J. Ellingson\, University of Toledo\, Ohio\nBi
 o: The Ellingson Group focuses on synthetic capabilities\, optical spectro
 scopies\, and materials innovation for advancing photovoltaic and related 
 technologies.  Recently\, our group has synthesized high quality iron cha
 lcogenides including iron pyrite nanocrystals (FeS2)\, and successfully ap
 plied these as a high-performance back contact to CdTe solar cells.   We
  also study ultrafast charge carrier processes in semiconductor thin films
  and PV devices\, colloidal semiconductor nanocrystals and quantum dots\, 
 molecular absorbers such as single-wall carbon nanotubes (SWNTs)\, and nan
 ostructured assemblies such as nanocrystal arrays formed through self-asse
 mbly routes. We utilize a variety of steady-state and time-resolved laser 
 spectroscopy techniques such as time-resolved photoluminescence and pump-p
 robe (transient absorption) to understand charge carrier dynamics as well 
 as exciton transport processes.\nThe Ellingson Group is also interested in
  the assembly of colloidal semiconductor nanocrystals for use in simple so
 lar cells with the potential for highly-efficient operation. A variety of 
 inorganic semiconductors are of interest\, especially those which utilize 
 abundant\, inexpensive elements such as Cu\, Zn\, Sn\, S\, Fe\, and Si.\n
