Study of the transient electroluminescence (EL) behavior at turn-on upon the application of a single voltage pulse is presented. Based on the continuity equations which describe the carrier dynamics, and on the recombination current which describe the EL output, we present a theoretical model to explain the slow rise of the EL associated to the electron packet motion in the bulk. The model enables...
Using Volterra series we resolve analytically the non-linear rate equations describing the time evolution of the charge carrier concentration in an Al/6T/ITO cell when the device is illuminated and charge carriers are uniformally generated in the bulk at a known rate. We present the analytic expressions of the charge carrier densities in the bulk as a function of time and the expression for the photocurrent...
