DESCRIPTION:Speakers: Egmont Rohwer (Stellenbosch University)\nD149 Dye ha
 s proven to be an effective photo-absorber for use in dye sensitized solar
  cells. Pump-probe measurements were conducted on D149 dye as well as D149
  adsorbed to Zinc Oxide semi-conducting particles. Ultrafast dynamics on a
  sub-ps time scale\, easily resolved by the current experimental setup at 
 the LRI\, were observed in both samples. Significant quenching of the exci
 ted state dynamics of the D149 molecule was seen in samples adsorbed to Zi
 nc oxide\, indicating the occurence of intermolecular charge transfer of p
 hoto-excited electrons from the singlet excited state of the D149 molecule
  and subsequent injection into the conduction band of the Zinc Oxide parti
 cles.\n\nhttps://events.saip.org.za/event/7/contributions/4852/
