Study of the crystallization process kinetics of perovskites and their precursors
Sršeň, Bohdan ; Gavranović, Stevan (referee) ; Zmeškal, Oldřich (advisor)
This thesis focuses on the properties of perovskite materials and examines the methods for preparing layers and potentially monocrystals of these materials. Emphasis is placed on analyzing the electrical and optical properties of perovskites. The experimental part of the thesis is dedicated to the preparation of perovskite material layers and subsequent measurement of their electrical properties during the crystallization process and after its completion. The prepared samples exhibit a macroscopic size due to the interdigitated electrode structure, ensuring a large active surface area. Special attention is given to the influence of nano-particles on the crystallization process and the resulting current-voltage (I-V) characteristics of the prepared samples. Understanding how the presence of nano-particles affects the crystallization and electrical properties of perovskite layers is crucial. These insights are necessary for further optimization of the preparation processes and enhancing the performance of perovskite materials in their final applications. The thesis provides an overview of the properties of perovskites and their preparation. The experimental results yield important insights into the relationship between nano-particles, crystallization, and electrical characteristics of perovskite layers.
