Organic Semiconductors

This book is a compilation of research articles related to the application of organic semiconductor materials in the field of electronics such as field effect transistors, light emitting diodes and in harvesting solar energy via solar cells. Chapter 1 acquaints the reader with the progress made so far and future potential in the field of organic semiconductors highlighting their employment as organic light emitting diodes (OLEDs) for flexible electronics and lighting, as organic field effect transistors (OFETs) and as organic photovoltaics. In chapter 2, a novel technology of utilizing aluminum laminations as moisture barriers against ambient aggressors in order to enhance device performance, especially in organic solar cells and OLEDs has been demonstrated. Chapters 3-5 focus on the fabrication routes of organic electronics such as OFETs and organic solar cells. The further chapters of this book are broadly classified into three categories addressing the three key applications of these materials OFETs, organic solar cells and OLEDs. In chapters 6-13, the various materials, their synthesis, properties, processing parameters and their application in OFETs has been illustrated. Application of OFETs in detecting blood gases such as ammonia has been shown in chapter 13. Chapters 14- focuses on critical light instability in CB/DIO processed PBDTTT-EFT:PC71BM organic photovoltaic devices. I strongly believe that this book will help students, engineers and researchers working in the field of electrical engineering, chemistry, physics and material science to build upon their existing knowledge. The collection of articles and review articles is upto date and the reader can keep themselves abreast with the latest developments in the field of organic semiconductors through this book.
