Abstract : Optoelectronic devices such as xerographic photoreceptors (PRs) and light emitting diodes (LEDs) represent two examples of promising applications of semiconducting polymers. In the former example, efficient generation of charge carriers from absorbed light is the central focus. Th the latter examples, efficient generation of light from injected charges is the goal. To explore the nature of these light to charges exchange processes in electronic polymers we have fabricated and evaluated bilayer photoreceptors and bilayer LEDs from conjugated polymers. The efficiencies and other performance characteristics of these devices are shown to depend on not only molecular structure and intrinsic properties of the materials but also on the "polymer device engineering" factors such as the polymer/polymer interfaces. Electronic polymers; light-emitting diodes; xerographic photoreceptors; polymer/polymer interfaces.
