A number of devices based on NPB (N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine) and TPBi (2,2′,2′′-(1,3,5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole)) conducting layers, CBP (4,4′-bis(N-carbazolyl)-1,1′-biphenyl) as a host and BPTZ-DBTO2 (3,6-bis(10H-phenothiazine-10-yl)-9H-fluorene-[dibenzothiophene-S,S-dioxide]) as an emitter were taken as an example to validate the method. Using equivalent electrical circuits, values of capacitance and conductivity of both hole- (HTL) and electron-transport (ETL) layers were determined and analysed separately. Those parameters, as well as current-voltage characteristics, were used to calculate (i) mobility (μ, cm2 V-1 s-1) of both types of charge carriers, (ii) charge density (n, cm-3) of the charge carriers, and (iii) electric field intensity (E, V m-1) in both transport layers as functions of the applied voltage. © 2018 The Royal Society of Chemistry.}, keywords={Aromatic hydrocarbons; Capacitance; Charge carriers; Current voltage characteristics; Electric fields; Electric network analysis; Electron transport properties; Spectroscopy, Applied voltages; Conducting layers; Dibenzothiophenes; Electric field intensities; Electron transport; Equivalent electrical circuits; Impedance spectroscopy; Transport layers, Organic light emitting diodes (OLED)}, funding_details={H2020 Marie SkÅodowska-Curie ActionsH2020 Marie SkÅodowska-Curie Actions, MSCA}, funding_text 1={The authors gratefully acknowledge the financial support of project Excilight: Donor–Acceptor Light Emitting Exciplexes as Materials for Easy-to-tailor Ultra-efficient OLED Lightning (H2020-MSCA-ITN-2015/674990) financed by Marie Sklodowska-Curie Actions within the framework programme for research and innovations Horizon2020.}, references={Klauk, H., (2006) Organic Electronics: Materials, Manufacturing and Applications, , John Wiley & Sons, New York; Special Issue Organic Electronics (2015) ChemPhysChem, 16, p. 1097; Adachi, C., Baldo, M.A., Thompson, M.E., Forrest, S.R., (2001) J.
