Electronic transport properties of polymer light-emitting diodes (PLEDs) were determined using a machine learning model developed with complex impedance spectra generated by device simulation. The mobilities and bimolecular recombination coefficients were instantaneously determined by the machine learning model using experimentally-obtained complex impedance spectra of PLEDs as inputs.
