“…The fitting of the spectrum parameters was carried out using the EIS-analyzer software package. The analysis of the impedance measurement results was carried out according to the diffusion-recombination model [14,15]. As a result of the analysis of the impedance spectra, the following electric transport parameters were determined: τ effthe effective lifetime of charge carriers; k eff -the effective rate of extraction of charge carriers, D eff -the effective diffusion coefficient of charge carriers and μ -the mobility of charge carriers.…”

Nanocomposite polymer solar cells were obtained. Nanostructures of phthalocyanines were added to a mixture of photoactive layer at a concentration of 0.5%. The photoactive layer was applied by centrifugation at a rotation speed of 1500 rpm. Atomic force microscope images of the surface of the films were measured. Absorption spectra of composite films were measured. It was found that the introduction of phthalocyanine nanostructures into the photoactive photoactive layer leads to a broadening of the spectrumand an increase in the optical density at the absorption maximum by 2.1 times for nanorods and 1.9 times for nanoparticles. The current-voltage characteristics of composite organic solar cells were measured. To do this, an aluminum electrode with a thickness of 100 nm was sprayed onto the surface of the photoactive layer at 10-5Torr. It is shown that when the photoactive layer was doped with nanorods and phthalocyanine nanoparticles, the short-circuit current density of the current-voltage characteristics increased by 8% and 5%, respectively, and the efficiency value increased to 4.58% and 4.51%, respectively. The impedance spectra of composite organic solar cells were measured. Analysis of hodographs of nanocomposite films showed that doping of the photoactive layer with nanorods and phthalocyanine nanoparticles leads to an increase in the diffusion length by 2.2 times and 1.8 times, respectively, and an increase in the mobility of charge carriers by 1.4 times and 1.2 times.
