The application of an electric field (Ecast) during solvent vaporization is shown to inhibit the formation of ordered domains in thin films of a poly(phenylenevinylene) derivative, resulting in a homogeneous environment favorable for charge transfer. An order-of-magnitude increase in charge-carrier mobility (see Figure) is achieved by the elimination of these commonly found domains.
