Solar energy is considered one of the most important forms of renewable energy. Silicon solar cells are commonly used in the photovoltaic industry, but their higher production costs and complicated fabrication processes make them less affordable. Various other technologies, such as perovskite solar cells and dye-sensitized solar cells, are also emerging.

Among these, perovskite solar cells are promising type of solar cells, offering comparable efficiency to that of silicon solar cells, at significantly lower costs. However, one of the drawbacks of perovskite solar cells is their relatively short lifespan, which limits their applications. Researchers are actively working to improve both the lifetime and efficiency of perovskite solar cells.

This book begins by covering the basics of solar energy and the principles and different types of solar cells. The focus is then put on perovskite solar cells, how they work, their advantages and challenges, and what sets them apart from other solar cells. Device fabrication techniques and recent advancements in the field are discusses next, finishing up with a look into the future of solar cell technology.

This book provides a thorough introduction to graph mining and addresses foundational concepts and advanced techniques along with practical applications across various fields.  As graphs have become increasingly vital for data representation in domains such as social network analysis, bioinformatics, and transportation, there is a growing demand for a comprehensive source that covers both theory and practical insights. This book seeks to fill that gap by offering clear explanations, practical examples, and actionable insights, making complex graph mining techniques accessible to students, postgraduate readers, and researchers.  The authors also provide an extensive investigation into the process of gaining insightful knowledge from graph representations, ranging from interpreting intricate relationships to decoding complex data structures.  Readers will learn to identify anomalous patterns, locate communities, arrange nodes, predict connections, and evaluate graphs effectively.  

Ionic liquids are organic salts that are typically in liquid phase when their temperature is below 100 °C (212 °F). They are nonflammable and have very low vapor pressure, which make them environmentally friendly alternative to organic solvents. Chemical reactions with ionic liquids can be more efficient, results in less waste and pollution, lower energy consumption, safer manufacturing processes, and reduced resource usage.

This book is focused on ionic liquids and their applications. The book begins by introducing ionic liquids, their structure and properties and their synthesis and characterization methods, next, synthesis methods with ionic liquids are reviewed, and then their industrial applications in various fields and finally emerging developments in the area.
