SUMMARY:Soft X-ray spectro-microscopy of polymer solar cells - Benjamin Wa

DESCRIPTION:Solar cells based on thin blend films of conjugated polymers a
 nd/or fullerene derivatives are a promising alternative to the currently a
 vailable silicon-based solar cells. However\, these systems tend to displa
 y complex segregation of the organic components during film formation and 
 the fundamental details of the relationship between the morphology of conj
 ugated polymer blend films and their performance in photovoltaic devices i
 s still not clear.\n\nIn this talk\, I'll present our experimental efforts
  to map out the morphology and photovoltaic performance of solar cell devi
 ces based on segregated PFB:F8BT blend films\, utilising both conventional
  scanning transmission soft X-ray spectromicroscopy (STXM) and our novel e
 xtension to STXM\, Soft X-ray Beam Induced Current (SoXBIC).
