SUMMARY:Plastic Fantastic: Organic Solar Cells as a Large-Scale Renewable 
 Energy Source - Mark Wilson

DESCRIPTION:Over the past two decades organic (i.e. carbon-based) semicond
 uctors have gone from a laboratory curiosity to the dominant technology fo
 r high-end smartphone displays. More recent research has studied their sui
 tability as photovoltaic cells\, exploiting the exquisite molecular contro
 l granted by organic chemical synthesis\, and the large-scale fabrication 
 made possible by solution-processable polymers. I will try to give an over
 view of the field\, and explain the role of my work\, which uses ultrafast
  transient absorption spectroscopy to study materials that can make better
  use of\nhigher-energy (i.e. blue) light by generating multiple electrons 
 for every absorbed photon.
