- Аннотация: The using of polymeric materials as the basis of photovoltaic cells provides high manufacturability and low cost of production of flexible polymer solar cells (PSC) of a large area. The recent increase in a parameter of the solar energy conversion efficiency (up to 10 %) for materials based on conjugated polymers and fullerenes makes commercialization of plastic solar cell gainful. The peculiarity of the manufacture of PSC leads to the fact that the photoactive layer of photovoltaic cells is formed as a thermodynamically unstable system (with a kinetically frozen state). As a result of constant heating/cooling cycles, a gradual phase separation of the initial components occurs in them. Thus, the next obstacle to the widespread introduction of polymer solar cells is their lack of durability. In the report, we discuss the problems of building and modeling polymer nanocomposites based on conjugated polymers and fullerene, see Fig. 1. We have constructed and parameterized a coarse-grained model of a photoactive layer based on selected polymers and PC61BM. This model is used to study the structure of the photoactive layer. In addition, within the framework of the atomic molecular dynamics method, we carried out a study of the miscibility of selected conjugated polymers with PC61BM. The obtained results make us possible to predict the thermodynamic stability of polymeric solar cells. This work was performed using the resources of the Supercomputer Center of the Lomonosov Moscow State University with the financial support of the Russian Foundation for Basic Research (Project No. 19-53-52004) and the Ministry of Science and Technology of Taiwan (Project MOST 108-2923-E-002-001-MY3).
