Preface

a cleaner and greener footprint.

The demand for clean environment in our current society has increased with large-scale eco‐ nomic developments and population growth. The standard energy sources based on fossil fuels are limited and pollute the environment, leading to climatic change on a global scale. Taking care of the environment today is a sustainable act for the generations of tomorrow. The process of developing new techniques and improving older types of technologies is still ongoing. The most important thing is to understand that remediation actions need to be jus‐ tified and optimize the adopted actions and must do more good than harm. The end results should always be a balance between risks, costs, benefits, and remediation viability. Solar energy and other renewable sources enable us to meet the demand for energy while offering

Based on the developments in the field of solar technology, we decided to compose a book based on materials and concepts in solar cells. In parallel with the growth rate of renewable energy, essential attention is being paid to the development of advanced techniques and ma‐ terials for the effective utilization of energy resources. An attempt has also been made to provide the fundamental understanding of the functioning of solar cells. The main objective of writing this book is to create a comprehensive and easy-to-understand source of informa‐ tion on the advances in this rapidly growing research area. This book includes enough infor‐ mation on the basics to be used as a textbook undergraduate coursework in engineering and the sciences. The inclusion of advanced concepts and research trends will also make it useful as a reference for scientists and professionals. We hope that the book can serve its function

*Emerging Solar Energy Materials* is divided into 2 parts comprising 12 chapters written by leading experts in the solar cell field and is organized with the intention to provide a big picture of the latest progress in the solar cell field and at the same time give an in-depth discussion on fundamentals of solar cells for interested audiences. In this book, each part opens with a new author's essay highlighting their work for contribution toward solar ener‐ gy. To help the reader evaluate progress and recognize how difficult some problems are, the chapters present charts, graphs, and figures to help illustrate the scope of environmental is‐ sues; the text's main focus is on identifying major issues and giving appropriate examples to

Preparing such a book is not possible without the support from others. We want to express our special thanks to the authors' hard work and contributions, copyright owners, and re‐ viewer's comments and suggestions. Without all these support, it would not have been pos‐

to draw attention to this emerging solar cell field with a great potential.
