While there is information available in handbooks on polythiophene chemistry and physics, until now, few if any books have focused exclusively on the most forwardly developed electrically conductive polymer, Poly (3,4-ethylenedioxythiophene)-otherwise known as PEDOT. This resource provides full chemical, physical, and technical information about this important conducting polymer, discussing basic knowledge and exploring its technical applications. Presented information is based on information generated at universities and through academic research, as well as by industrial scientists, providing a complete picture of the experimental and the practical aspects of this important polymer.

PEDOT is currently the most widely used polymeric material in research and development. Over the past 10 years, PEDOT has been investigated for potential organic thermoelectric applications because of its superior thermoelectric and mechanical properties compared with other conductive polymers. However, many challenges remain to be solved before it is translated into key technologies. Advanced PEDOT Thermoelectric Materials summarizes current progress and the challenges of PEDOT thermoelectric materials, while clarifying directions for future development. This book provides a comprehensive overview of chemical, physical, and technical information about this organic thermoelectric polymer. The authors also give details about the theoretical basis of PEDOT, including preparation and characterization, and its development as a high-performance thermoelectric material. - Provides an overview of techniques to optimize the thermoelectric performance of PEDOT materials. - Introduces the fundamentals of PEDOT, including material synthesis, characterization, preparation, thermal transport, and more. - Discusses emerging applications in thermoelectric devices and future directions.

Written in the perspective of an experimental chemist, this book puts together some fundamentals from chemistry, solid state physics and quantum chemistry, to help with understanding and predicting the electronic and optical properties of organic semiconductors, both polymers and small molecules. The text is intended to assist graduate students and researchers in the field of organic electronics to use theory to design more efficient materials for organic electronic devices such as organic solar cells, light emitting diodes and field effect transistors. After addressing some basic topics in solid state physics, a comprehensive introduction to molecular orbitals and band theory leads to a description of computational methods based on Hartree-Fock and density functional theory (DFT), for predicting geometry conformations, frontier levels and energy band structures. Topological defects and transport and optical properties are then addressed, and one of the most commonly used transparent conducting polymers, PEDOT:PSS, is described in some detail as a case study.

Bachelor Thesis from the year 2014 in the subject Technology, grade: 1,0, Friedrich-Alexander University Erlangen-Nuremberg, course: Nanotechnologie, language: English, abstract: This bachelor thesis presents the fabrication and evaluation of large-scale full-solution roll-to-roll processed, ITO-free flexible organic solar cells in a modified inverted device geometry by gravure printing on a discrete laboratory-scale printing system. The layer stack is based on flexible PET substrate whereupon the back silver cathode was printed on top. The electron transport layer of ZnO and a double light absorbing photoactive layer of P3HT:PCBM, the hole transport layer of PEDOT:PSS and front silver anode were printed consecutively. All layers were roll-to-roll gravure printed from solution under full ambient vacuum-free conditions at a web speed of 2 m min−1. The completed solar cells were characterized by J-V and comprising layers by light beam induced current measurements. For fast testing and reproducibility experiments the remaining layers of the stack after each gravure printed film were deposited by slot-die coating and flexographic printing on a single roll coating system. Unfortunately functional organic solar cells of a fully gravure printed layer stack could not be found. A power conversion efficiency of 0.15 % of partly roll-to-roll gravure printed and residuary roll-based slot-die coated and flexographic printed organic solar cells under AM1.5G illumination was obtained. The thesis contains a brief introduction in the topic of renewable energies and organic photovoltaic followed by the state of art in two-dimensional gravure printing organic solar cells and the motivation to particularly foreground this fabrication method. In the fundamentals part the working principle, device geometries, affiliated by the concept of ITO-free organic solar cells and materials in an organic photovoltaic device including characterization methods are presented. Afterwards large-scale manufacturing techniques of organic photovoltaic comprising coating and printing technologies are reviewed and the roll-to-roll manufacturing strategies are introduced. In the experimental part the design, machinery and equipment used and fabrication of gravure printed flexible organic solar cell are chronologically described in detail in connection with presenting and discussing the results after characterizing the completed solar cells. Challenges that were faced during the studies are described subsequently and solutions of appeared problems are presented. A conclusion and outlook finalizes the thesis.
