In recent decades, the way human beings interact with technology has been significantly transformed. In our daily life, ever fewer manually controlled devices are used, giving way to automatized houses, cars, and devices. A significant part of this technological revolution relies on signal detection and evaluation, placing detectors as core devices for further technological developments. This book introduces a versatile contribution to achieving light sensing: Organic Semiconductor Devices for Light Detection. The text is organized to guide the reader through the main concepts of light detection, followed by a introduction to the semiconducting properties of organic molecular solids. The sources of non-idealities in organic photodetectors are presented in chapter 5, and a new device concept, which aims to overcome some of the limitation discussed in the previous chapters, is demonstrated. Finally, an overview of the field is given with a selection of open points for future investigation.

Über Autor(innen)

Dr. Kublitski obtained his master’s degree at Paraná Federal University in Brazil. In 2016, he moved to Germany to join the group of Prof. Dr. Karl Leo at the Dresden Integrated Center for Applied Physics and Photonic Materials, where he pursued his PhD. During this period, he worked on organic photodetectors (OPDs), investigating fundamental mechanisms, such as dark and noise current generation and photomultiplication in narrowband devices. During his PhD, Dr. Kublitski also contribute to several projects involving organic solar cells and properties of organic semiconductor materials, where charge-generation, charge-transfer and band-gap engineering were target. These projects resulted in over 15 important publications. Currently, he is a postdoctoral fellow in the same group. His research topics go towards the development of new OPD structures, formation of trap states and their relation with noise current in optoelectronic devices as well as charge transport.
