Аннотация:The effect of spherical SiO2 nanoparticles (NPs) embedded in the electrode layer of PEDOT:PSS on the efficiency of organic solar cells (OSC) based on small molecules was studied in detail. We show that embedding SiO2 NPs of 50 nm in diameter increases the power conversion efficiency (PCE) by 15%, and this increase weakly depends on the NPs concentration in the buffer layer. Also, we calculated the interaction of radiation with a model three-layer system (ITO, buffer layer, active layer) with embedded NPs in buffer layer and analyzed the directional patterns of spherical SiO2 NPs of various sizes in such a three-layer system. The calculation results allow interpreting the experimental results on increasing the PCE as a result of light scattering by the NPs.
