Design of Perovskite Photovoltaic Solar Cells and Research of their Stability

The work in the first part describe the design of a perovskite photovoltaic cell with planar inverse structure using photovoltaically active material CH3NH3PbI3 and CH3NH3PbI3-xClx. The theoretical description of perovskite materials is supplemented by knowledge of degradation mechanisms reducing the resulting stability of samples and also presents a comprehensive overview of the technology development. The following text brings an innovative process for the perovskite photovoltaic cells production, which has enabled manufacturing of reproducible samples with parameters comparable to the foreign workplaces. The second part of the research analyzes the influence of the external environment to the samples and based on experimental outputs explains possible degradation mechanisms of perovskite material. At the final part of the dissertation thesis is presented and characterized unique structure of planar inversion perovskite cells with a material composition increasing the resistance against external humidity
