| Abstract Scope |
Developing technologies for simultaneous energy conversion and storage is crucial for future advancements. Polar perovskite oxides stand out as versatile materials for multifunctional energy systems, capable of converting mechanical vibrations and thermal fluctuations into electrical energy via piezoelectric and pyroelectric effects. These materials also utilize internal electric fields to enhance electron-hole recombination in solar cells and drive chemical reactions like water splitting. The functional properties of perovskites are governed by their crystal structure, which is influenced by processing conditions, defect concentrations, thermal treatments, and external stimuli such as thermal, electrical, and mechanical fields. Understanding these structure-property relationships is essential for tuning multifunctionality. This contribution examines the structure-property relationships of polar perovskite oxides under applied electric and mechanical fields. |
