Ultrafast photoinduced electron transfer in coumarin 343 sensitized TiO2-colloidal solution [PDF]

, 2012
Photoinduced electron transfer from organic dye molecules to semiconductor nanoparticles is the first and most important reaction step for the mechanism in the so called “wet solar cells” [1]. The time scale between the photoexcitation of the dye and the
