Abstract: Using the time-of-flight photocurrent measurements, we investigate the hole transport properties of polymer 2-methoxy, 5-(2’-ethyl-hexyloxy)-1, 4-phenylene vinylene (MEH-PPV). The change of hole transport properties from non-dispersive transport to a dispersive type is presented, with the increasing excitation wavelength near the MEH-PPV absorption edge. At room temperature, the effective mobility of MEH-PPV depends on the applied electric field as commonly seen in some organic materials.
