**7. Conclusions**

This chapter primarily addresses the fundamental concepts of perovskites, their structure, classification of perovskites, their synthesis, their distinctive features, and their applications. Because of its many unique properties, including enormous magnetoresistance, multiferroics, superconductivity, etc., perovskite structured materials have received a great deal of research attention. Perovskites have unique and unusual physical properties that have been extensively studied for both real-world use and theoretical research. Applications for photonic and optoelectronic devices, effective solar cells, fuel cells, spintronics, electrical machines, random - access memory, electrochemical double layer capacitors, and other novel device concepts are just a few of the many novel device concepts that have been made possible by perovskites in the field of materials science.
