DESCRIPTION:According to a recent report by the US Department of Energy\, 
 “world demand for energy is projected to more than double by 2050 and to
  more than triple by the end of the century.” Thus\, the development of 
 alternative energy sources is now recognized by government\, society and t
 he global community as an urgent need. Plastic solar cells potentially can
  offer low cost\, large area\, flexible\, light-weight\, clean\, and quiet
  alternative energy sources for indoor and outdoor applications. In this t
 alk\, I will give an overview of the current progress\, challenges\, and r
 esearch opportunities in organic solar cells. Then\, I will go over some r
 ecent results in our group. We have developed nanoscale characterization t
 echniques to probe film morphology and interfaces in multilayer optoelectr
 onic devices\, to image the donor-acceptor networks laterally and vertical
 ly\, to assign phase domains to the donor and the acceptor components\, an
 d to study nanoscale charge generation\, transport and external quantum ef
 ficiency in polymer solar cells. \n
