“…Thus, the optimal ETL thickness should be as small as possible to provide good blocking properties at the tops of the layers, resulting in fast electron transfer and low resistive losses [23]. For HTL, the layer thickness is also of great importance, since the minimum time for the charge to pass through the layers will increase the main characteristics of the PSC by increasing the conductivity and reducing the probability of recombination [24][25][26][27].…”

Large-scale deployment of the perovskite photovoltaic technology using such high-performance materials as СH3NH3PbI3may face serious environmental issuesin the future. Implementation of perovskite solar cellbased on Sncouldbe an alternative solution for commercialisation. This paperpresents the results of a theoretical study of a lead-free, environmentally-friendlyphotovoltaic cellusing СH3NH3SnI3as a light-absorbing layer. The characteristics of a photovoltaic cell based on perovskite were modelled using the SCAPS-1D program. Various thicknesses of the absorbing layer were analysed,and an optimised device structure is proposed,demonstratinga high power conversionefficiencyof up to 28% at ambient temperature. The analysis of the thicknesses of the СH3NH3SnI3absorbing layer revealedthat at a thickness of 500 nm, performance is demonstrated with an efficiencyof 27.41 %, a fill factor of 85.92 %, a short circuit current density of 32.60 mA/cm2and an open-circuit voltage of 0.98 V. The obtained numerical results indicate that the СH3NH3SnI3absorbing layer may be a viable replacement forthe standard materials and may form the basis of a highly efficient technology of the environmentally-friendlyperovskite solar cells.

“…It can be seen from the figure that the initial PEDOT:PSS film has a maximum at a wavelength of λ 1 = 214 nm with a spectral half-width of 10.2 nm. In the absorption spectra of all films, a shoulder λ 2 is observed with a maximum at 227 nm, which is associated with the absorption of the PSS -poly(styrenesulfonate) [20,23]. When ethyl alcohol is added to the film during preparation, the positions of the maxima in the absorption spectra do not change, only a decrease in the optical density values and a decrease in the half-width are observed (Figure 3a).…”

“…Fast transport of injected holes to the outer electrode is very important, since this reduces the probability of their reverse recombination. In our case, fast hole transport is provided by improving the structure of PEDOT:PSS after adding isopropyl alcohol to the initial solution, which leads to an improvement in the quality of the PEDOT:PSS/ITO interface [20].…”

“…Previously, we studied the effect of modification of the structure of the PEDOT:PSS polymer with hole conductivity on the optical, electrical transport and photovoltaic properties of an organic solar cell based on a P3HT:PC60BM bulk heterojunction [20]. It was shown that thermal treatment with the addition of isopropyl alcohol to the PEDOT:PSS polymer solution leads to a change in the structural and optical properties of the films.…”

The paper presents the results of a study of the effect of alcohol solvents on the surface structure, optical and electrical characteristics of a Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate filmsannealed at a low atmospheric pressure of 10-3millimetersof mercury. It has been found that the modification of the surface of a polymer film with ethyl and isopropyl alcohols leads to a change in the surface morphology, optical and electrical transport properties of the polymer. It is shown that when the Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate film is modified with alcohol solvents, the absorption spectra show a decrease in the absorption of the polystyrene sulfonate aromatic fragment. It is shown that the structural features of the Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate surface morphology affect the electrical transport parameters of films, such as the resistance of the Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate film, the charge carrier transfer resistance at the Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate/electrode interface, the effective extraction rate, and the effective time of flight of charge carriers. The optimal technological parameters for the production of films have been determined, at which the electrical transport properties of Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate films annealed at low atmospheric pressure increase

The paper presents the results of studying the influence of the environment on the surface structure, optical and electrical characteristics of the PEDOT:PSS film. The studies have been carried out in three different types of atmosphere under the same conditions of thermal annealing of the films. It has been established that the modification of the surface of a polymer film with ethanol and isopropanol in vacuum, in a nitrogen atmosphere, and in the air atmosphere leads to a change in the surface morphology and the optical electric transport properties of the polymer. Depending on the environment, when the PEDOT:PSS film is modified with a certain concentration of ethyl and isopropyl alcohols, the absorption spectra show a shift in the absorption maximum responsible for PEDOT to the short-wavelength region of the spectrum, as well as a decrease in the absorption peak of the part of the spectrum responsible for the absorption of the aromatic fragment PSS. It is identified that the structural features of the PEDOT:PSS surface morphology affect the electrical transport parameters of the films: Rh is the resistance of the PEDOT:PSS polymer film, Rext is the charge carrier transfer resistance at the PEDOT:PSS/electrode interface, keff is the effective charge carrier extraction rate and τeff is the effective transit time of charge carriers. The optimal technological parameters for film production have been determined, at which the electrical transport properties of PEDOT:PSS polymer films are increased.
