Аннотация: Charge carrier mobility and photovoltaic parameters was studied in poly[2-methoxy-5-(2’-ethyl-hexyloxy)-1,4-phenylene vi-nylene] (MEH-PPV) based films prepared by different methods. Polymer films have been obtained by drop casting and new method of slow solvent elimination (SSE). Transient currents demonstrate non-dispersive and dispersive behavior in SSE and drop-cast films, respectively. In SSE films, hole drift mobility increases from 2.2-10(-6) to 7.0-10(-6) cm(2)V(-1)s(-1) with the electric field increase from 4.2-10(4) to 2.9-10(5) V center dot cm(-1). These values are greater than the corresponding ones in drop-Gast films by a factor of 4-5. This behavior indicates the difference in the morphology of the MEH-PPV films obtained by different methods. Possible reasons of the observed mobility enhancement in the SSE films are discussed.
