This textbook introduces the physical concepts required for a comprehensive understanding of pa€“n junction devices, light emitting diodes and solar cells. Semiconductor devices have made a major impact on the way we work and live. Today semiconductor pa€“n junction diode devices are experiencing substantial growth: solar cells are used on an unprecedented scale in the renewable energy industry; and light emitting diodes (LEDs) are revolutionizing energy efficient lighting. These two emerging industries based on pa€“n junctions make a significant contribution to the reduction in fossil fuel consumption. This book covers the two most important applications of semiconductor diodes a€“ solar cells and LEDs a€“ together with quantitative coverage of the physics of the pa€“n junction. The reader will gain a thorough understanding of pa€“n junctions as the text begins with semiconductor and junction device fundamentals and extends to the practical implementation of semiconductors in both photovoltaic and LED devices. Treatment of a range of important semiconductor materials and device structures is also presented in a readable manner. Topics are divided into the following six chapters: Semiconductor Physics The PN Junction Diode Photon Emission and Absorption The Solar Cell Light Emitting Diodes Organic Semiconductors, OLEDs and Solar Cells Containing student problems at the end of each chapter and worked example problems throughout, this textbook is intended for senior level undergraduate students doing courses in electrical engineering, physics and materials science. Researchers working on solar cells and LED devices, and those in the electronics industry would also benefit from the background information the book provides.April 24, 2012 10:10 Printer: Yet to come Principles of Solar Cells, LEDs and Diodes Summary A solar cell consists of a p-n junction in which sunlight generates electron-hole pairs that are collected by the external circuit and provide electrical power. ... Light absorption in a solar cell is sensitive to the type of bandgap.
