Solar energy has paved the alternative way to fossil fuels for present and future energy demands. Dye‐sensitized solar cells (DSSCs) are one of the most promising technique to harvest solar energy and convert in to electrical energy because of their ease of production, low cost, flexibility, relatively high conversion efficiency, and low toxicity to the environment. DSSC consists of components such as electrolyte, dye, counter electrode, and photoanode. Among these, photoanode plays a vital role and serves as a support for dye molecules and transport photo‐excited electrons. Performance of the devices is greatly affected by charge generation, collection, and charge recombination occurs at interfaces (TiO2 photoanode/electrolyte and FTO substrate/electrolyte) and are influenced by properties of the interfacial materials.
This new book gathers and surveys a variety of novel ideas for improving the efficiency of photoanode from various experts of interdisciplinary fields of chemist, physicist, materials scientist, and engineers to widely explore the materials development in the field of DSSC to achieve higher solar energy conversion efficiency.
This book is very attractive for multidisciplinary researchers. Moreover, this is much useful for the beginners who are working in the multidisciplinary area of nanoscience and nanotechnology, physics, chemistry, energy science and technology, materials science, and engineering related to solar energy conversion through DSSCs. Further, this book will be helpful to upgrade their knowledge and establish their own research in the area of solar cells. Beyond that this book can be used for teaching and reference book for bachelor and master's degree level students including nanoscience and nanotechnology, physics, chemistry, energy science and technology, materials science, and engineering.
The first two chapters describe the operation principles, charge transfer dynamics, function of photoanode, challenges, and solutions for DSSC. Chapters 3 and 4 describe how the nanoarchitectures and light scattering materials are used as a photoanodes in DSSCs. Chapters 4 and 5 explain the role of compact layer and TiCl4 posttreatment during the fabrication of DSSCs. The remaining six chapters focus on engineering the interface with functional materials like doped semiconductors, binary semiconductors metal oxide based plasmonic nanocomposites, carbon nanotubes‐based nanocomposites, graphene‐based nanocomposites, graphitic carbon nitride (g‐C3N4) nanocomposites at the photoanode surface of DSSCs in order to achieve the higher efficiency.
Last but not least, we would like to express our thanks and gratitude to the authors for sharing their generous knowledge on photoanodes used in DSSCs for the benefits of our community. Without them, materializing of this book is impossible. We regret if any copyright is being infringed unknowingly. We acknowledge the sincere efforts of Wiley Book publishing authorities, for bringing the book in its final shape. The editors would like to dedicate this book to Prof. Ramasamy Ramaraj FASc, FNASc, FNA, CSIR‐Emeritus Scientist, Madurai Kamaraj University for his pioneer contribution in the area of solar energy harvesting.
