This book, Perovskite Photovoltaics for Sustainable Energy, aims to illuminate the incredible potential of perovskite materials while offering insights into their challenges, applications, and future directions. The unique crystal structure of perovskites underpins their remarkable properties, including high optical absorption, tunable band gaps, excellent charge transport, and solution-processability. These characteristics make them prime candidates for applications in energy harvesting. Yet, despite their promise, the road to widespread adoption of perovskites has not been without obstacles. Issues such as material stability, environmental impact, and large-scale fabrication remain active research and development areas.

This book is written to serve as a foundational resource for those new to perovskites and a comprehensive reference for experienced researchers and professionals. This book explores the fundamentals behind perovskite materials, discussing their structure, properties, and fabrication techniques. Subsequent chapters delve into their applications in photovoltaics, offering in-depth analyses of cutting-edge research and breakthrough technologies. By integrating perspectives from material science, engineering, and applied physics, this book aspires to foster interdisciplinary collaboration and inspire new ideas in the rapidly evolving fields of photovoltaics.
