Abstrakt: In this talk, I will present two important results we recently obtained in our lab. First, the identification of the hole and electron contributions to the carrier mobility of polymer/fullerene solar cell materials previously not possible with time resolved terahertz spectroscopy or other techniques. Second is the dependence of ultrafast THz decay with the excitation density which reveals a very high charge mobility (~0.1 cm2V-1s-1) that prevails for long time (nanosecond) after charge formation.
