Transient absorption spectroscopy of charge photogeneration yields and lifetimes in a low bandgap polymer/fullerene film

Charge photogeneration yields and energetics are determined for a low band gap co-polymer, PCPDTBT blended with PC(70)BM; the increase in charge photogeneration with dithiol is correlated with an increase in the free energy of charge separation.
