Abstract
The effect of acceptor energy level on electron transfer rate in blends of the polymer solar cell material poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7) is studied using time-resolved fluorescence. Fast electron transfer in <2 ps is observed for driving force between 0.2 and 0.6 eV and slower electron transfer outside this range. This dependence is described by Marcus theory with a reorganization energy of ≈0.4 eV.
