Abstract
This chapter provides an in-depth analysis of the structural properties of perovskite materials, highlighting their significance in the context of photovoltaic applications. It begins with a detailed exploration of the lattice structure, emphasizing the importance of the tolerance factor in determining the geometric stability and formability of perovskites. The discussion on lattice dynamic disorder sheds light on its impact on the electronic and optical properties of these materials, particularly focusing on lattice distortions and the presence of point defects. The narrative progresses to examine crystal growth via wet chemical processes, critically evaluating methods like Solution Temperature Lowering and Inverse Temperature Crystallization. These methods are analyzed within a thermodynamic framework to optimize crystal quality for enhanced device performance. Furthermore, the chapter delves into perovskite film formation, emphasizing the role of solvent volatility in influencing nucleation, grain morphology, and grain boundary formation. It concludes with an overview of structural defects and their implications for ion migration, underscoring the challenges and opportunities in improving the efficiency and stability of perovskite-based devices. This comprehensive analysis aims to advance the understanding of perovskite material science, paving the way for the development of more stable and efficient solar cells and optoelectronic devices.
