Abstract

Over the last decade, the science and technology of organic semiconductors has seen tremendous progress. The electrical and optical properties displayed by state-of-the-art organic semiconductors are remarkable in their tolerance to disorder, their ability to display high charge carrier mobility values and bipolar transport, and in that they can be engineered to display optical activity in the spectral range from the visible to the near-infrared. This new breed of organic materials is forcing us to reevaluate preconceived notions on how to optimize charge transport and photogeneration in disordered organic semiconductors. Lessons learned in the development of these remarkable organic semiconductors have rapidly spread across organic optoelectronic device platforms, from organic photovoltaics to organic field-effect transistors to organic light emitting diodes and to organic photodetectors, and thus are expected to provide further inspiration to continue advancing the science and technology of organic photorefractives. The purpose of this chapter is to provide a broad overview of current understanding of charge transport and photogeneration in organic semiconductors, going from crystalline to amorphous solids as well as to provide a brief overview of novel organic photoconductors that may offer significant opportunities to advance the science and technology of organic optoelectronic devices in general and of organic photorefractives in particular.
