Impedance spectra of ITO/PEDOT:PSS:Ag NPs/P3HT:PCBM/Al device with 60, 90, 120, and 150 μL of silver NPs in 1 mL of PEDOT:PSS layer under illumination devices along with fit results and equivalent circuit of devices. represents the series resistance, is capacitance between anode and cathode, is resistance, and is constant phase element of investigated layer, where and are parameters. When then the parameters correspond to some distribution of charge transport processes rather than to a single one.
