The continued expansion of organic electronics is driven by the cross-disciplinary expertise of both academic and industrial researchers. This synergy has led to significant advances in the fundamental understanding of these materials, as well as improvements in the efficiency and operational stability of organic electronic and optoelectronic devices. Many of these systems are being actively developed as part of next-generation, energy-efficient displays and solid-state lighting fixtures, as well as in photovoltaics for lost-cost solar energy utilization. To fully capitalize on these unique devices, significant gaps in fundamental understanding, as well as nontrivial technological challenges, must be overcome. This book brings together the academic and industrial communities to share recent advances in the field. Topics include device physics, development and characterization of new materials and device architectures, and novel processing methods. An important theme of the volume is the continuing pursuit of more efficient and longer-lived organic solar cells for commercial application.
