Analytical expressions to quantify the ratio between injection and space-charge-limited current from experimental I-V characteristics in organic diodes have been derived. These are used to propose a numerical model in which both bulk transport and injection mechanisms are considered simultaneously. This procedure leads to a significant reduction in computing time with respect to previous rigorous numerical models. In order to test the model, different diode structures based on two different polymers: poly(2-methoxy-5-{3',7'-dimethyloetyloxy}-p-phenylenevinylene) (MDMO-PPV) and a derivative of the poly(2,7-fluorene phenylidene) [PFP:(CN)(2)], have been fabricated. The present model is excellently fitted to experimental curves and yields the microscopic parameters that characterize the active layer.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/hopping transport; injection current; polymer light-emitting diode (PLED); space chargeinfo:eu-repo/semantics/article10.1109/TED.2007.912995info:eu-repo/semantics/openAccess3307 Tecnología Electrónica3306.02 Aplicaciones Eléctricas3307.09 Dispositivos Fotoeléctricos
