In this talk, we will present several recent fundamental results of the scientists from MSU, which have good perspectives for applications. As an example, we present our recent joint research with Prof.S.-A.Chen (NTHU, Hsinchu) on development semiconducting polymers/inorganic nanoparticles (NPs) hybrid solar cells (SC) with stable dispersion of NPs in the polymer matrix. The inorganic nanoparticles (NPs) serving as the electron acceptor/transportor can be randomly embedded in the conjugated polymer matrix to facilitate exciton dissociation. The morphology of the hybrid active layer, which significantly influences the charge separation, transport, and recombination kinetic, is crucial for the cell performance. The carrier transports in the polymer/inorganic NPs hybrid solar cells with the bulk heterojunction configuration are usually limited by the poor electron-conducting pathway because of insufficient connection between NPs. Particularly, we are interested in the question of whether it is possible to obtain controlled phase separation in a mixture of CP/NPs with the formation of a bicontinual NPs distribution (in this case, it is possible to obtain a better electron-conducting pathway through polymer matrix). To implement the task, a coarse-grained computer model was used, based on the dissipative particle dynamics method. We present results on the dependence of the morphology of the composite system on a composition of the CP/inorganic NPs mixture, the modification of the surface of NP by different ligands, and the structure of the CP chains. Poly (3-hexythiophene) as a polymer matrix and PbS NPs as a filler were used as prototypes of the real component of the mixture SP / oxide NPs. Based on the results obtained, preliminary recommendations can be formulated for the experimental production of a controlled morphology of the NPs dispersion in a polymer matrix.
