Hydrothermal synthesis of new generation high efficient and durable perovskite structures

Solar cells are among the prominent alternatives for renewable energy sources. Different materials have been researched to reduce the production costs of solar cells and to develop technologies compatible with new applications. With this study, it will have the potential to be used in solar cell applications, Perovskite structures that can increase the current yield were synthesized by hydrothermal method. In this thesis study, ABO3 with general formula, which is called as single perovskite, in different temperature and time combinations of TiO2 and lanthanides Lanthanum La(III), Cerium Ce(III), Samarium Sm (III) oxides, LaTiO3, CeTiO3 and SmTiO3 structures were created. In addition, tin oxide (SnO2) is seen as promising for perovskite solar cells due to its high electron mobility and superior photocatalytic stability. The single perovskite structures obtained for this purpose were converted into double perovskites in the form of A2BCO6 with the same method at different temperature and time combinations with SnO2. As a result of the characterization processes, it was observed that the doping was successful, and in the morphological results, the peak intensities and particle sizes were consistent with the literature, and superficially homogeneous structures were formed. These results are promising in photovoltaic applications for the nanostructures obtained.
