The field of organic electronics has seen a steady growth over the last 15 years. At the same time, our scientific understanding of how to achieve optimum device performance has grown, and this book gives an overview of our present-day knowledge of the physics behind organic semiconductor devices. Based on the very successful first edition, the editors have invited top scientists from the US, Japan, and Europe to include the developments from recent years, covering such fundamental issues as: - growth and characterization of thin films of organic semiconductors, - charge transport and photophysical properties of the materials as well as their electronic structure at interfaces, and - analysis and modeling of devices like organic light-emitting diodes or organic lasers. The result is an overview of the field for both readers with basic knowledge and for an application-oriented audience. It thus bridges the gap between textbook knowledge largely based on crystalline molecular solids and those books focusing more on device applications.

In this thesis steady-state (i.e. steady-state with respect to the applied voltage waveform) transient current-transient voltage [i(t)-v(t)], transient brightness-transient current [b(t)-i(t)], transient brightness-transient voltage [b(t)-v(t)], transient current [i(t)], transient brightness [b(t)], and detrapped charge analysis are introduced as novel organic light emitting device (OLED) characterization methods. These analysis methods involve measurement of the instantaneous voltage [v(t)] across, the instantaneous current [i(t)] through, and the instantaneous brightness [b(t)] from an OLED when it is subjected to a bipolar, piecewise-linear applied voltage waveform. The utility of these characterization methods is demonstrated via comparison of different types of OLEDs and polymer light emitting devices (PLEDs) and from a preliminary study of OLED aging. Some of the device parameters obtained from these characterization methods include: OLED capacitance, accumulated charge, electron transport layer (ETL) thickness, hole transport layer (HTL) thickness, OLED thickness, parallel resistance, and series resistance. A current bump observed in i(t)-v(t) curves is attributed to the removal of accumulated hole charge from the ETL/HTL interface and is only observed in heterojunctions (i.e. OLEDs), not in single-layer devices (i.e. PLEDs). Using the characterization methods developed in this thesis, two important OLED device physics conclusions are obtained: (1) Hole accumulation at the ETL/HTL interface plays an important role in establishing balanced charge injection of electrons and holes into the OLED. (2) The ETL behaves as a leaky insulator while the HTL more efficiently conducts charge and acts as a voltage-dependent resistor. A preliminary investigation of the aging properties of OLEDs is presented as further evidence of the utility of the novel characterization methods developed in this thesis. In general, aging is characterized by a softer turn on of the forward bias portions of i(t)-v(t) and b(t)-v(t) curves. Also, some aging recovery is possible if the OLEDs are subjected to a zero or reverse bias.

Research on advanced energy conversion devices such as solar cells has intensified in the last two decades. A broad landscape of candidate materials and devices were discovered and systematically studied for effective solar energy conversion and utilization. New concepts have emerged forming a rather powerful picture embracing the mechanisms and limitation to efficiencies of different types of devices. The Physics of Solar Energy Conversion introduces the main physico-chemical principles that govern the operation of energy devices for energy conversion and storage, with a detailed view of the principles of solar energy conversion using advanced materials. Key Features include: Highlights recent rapid advances with the discovery of perovskite solar cells and their development. Analyzes the properties of organic solar cells, lithium ion batteries, light emitting diodes and the semiconductor materials for hydrogen production by water splitting. Embraces concepts from nanostructured and highly disordered materials to lead halide perovskite solar cells Takes a broad perspective and comprehensively addresses the fundamentals so that the reader can apply these and assess future developments and technologies in the field. Introduces basic techniques and methods for understanding the materials and interfaces that compose operative energy devices such as solar cells and solar fuel converters.
