Organic and Hybrid Solar Cells
With the increasing world-energy demand there is a growing necessity for clean and renewable energy. This book offers an introduction to novel types of solar cells, which are processed from solution. We discuss fabrication, different architectures and their device physics of these solar cells on the bases of the author‘s teaching course on a master degree level. A comparison with conventional solar cells is given and the specialties of organic, hybrid and perovskite solar cells are emphasized.
Elementary Processes in Organic Photovoltaics
This volume presents the results of a multi-year research programme funded by the Deutsche Forschungsgemeinschaft (German Research Council), which explains how organic solar cells work. In this new promising photovoltaic technology, carbon-based materials are deposited by low-cost methods onto flexible substrates, thus allowing devices which open completely new applications like transparent coatings for building, solar cells integrated into clothing or packages, and many more. The investigation of organic solar cells is an interdisciplinary topic, covering physics, chemistry and engineering. The different chapters address topics ranging from the synthesis of new organic materials, to the characterization of the elementary processes such as exciton transport and separation, and the principles of highly efficient device design. /div
Ultrafast Dynamics In Molecules, Nanostructures And Interfaces - Selected Lectures Presented At Symposium On Ultrafast Dynamics Of The 7th International Conference On Materials For Advanced Technologies
Primary events in natural systems or devices occur on extremely short time scales, and yet determine in many cases the final performance or output. For this reason research in ultrafast science is of primary importance and impact in both fundamental research as well as its applications. This book reviews the advances in the field, addressing timely and open questions such as the role of quantum coherence in biology, the role of excess energy in electron injection at photovoltaic interfaces or the dynamics in quantum confined structures (e.g. multi carrier generation). The approach is that of a monograph, with a broad tutorial introduction and an overview of the recent results. This volume includes selected lectures presented at Symposium on Ultrafast Dynamics of the 7th International Conference on Materials for Advanced Technologies.
Photophysics of Molecular Materials
Carbon based pi-conjugated materials offer a broad range of applications, going from molecular electronics and single molecule devices to nanotechnology, plastic electronics and optoelectronics. The proper physical description of such materials is in between that of molecular solids and that of low-dimensional covalent semiconductors. This book is a comprehensive review of their elementary excitations processes and dynamics, which merges the two viewpoints, sometimes very different if not contrasting. In each chapter, a broad tutorial introduction provides a solid physical background to the topic, which is further discussed based on recent experimental results obtained via state-of-the-art t...
Polyfluorenes
With this collection of short review papers we would like to present a broad overview of research on poly?uorenes and related heteroanalogues over the last two decades. The collection begins with papers on the synthesis of po- ?uorenesandrelatedpolyheteroarenes, thenreportsphotophysicalproperties of this class of conjugated polymers both at the ensemble and the single chain level, continues with a discussion of the rich solid state structures of poly?uorenes, and ?nally switches to device applications (e.g. in OLEDs). In addition, two chapters are devoted to de?ned oligo?uorenesas lowmolecular weight model systems forpoly?uorenes and also to degradation studies. We feel that this up-to-date ...

FEATURES Describes the fundamental aspects and theory of nanogenerators Explores design strategies including material assessment based upon planned application Tailors the introduction and essential concept discussion for the industrial and research community Explores current applications, existing challenges, and the future outlook for the field
Unconventional Thin Film Photovoltaics
Covering both organic materials, where recent advances in the understanding of device physics is driving progress, and the newly emerging field of mixed halide perovskites, which are challenging the efficiencies of conventional thin film PV cells, this book provides a balanced overview of the experimental and theoretical aspects of these solar cell classes. Emphasis is placed on understanding the fundamental physics of the devices. The book also discusses modelling over many length scales, from nano to macro. The first book to cover perovskites, this is an important reference for industrialists and researchers working in energy technologies and materials.
Contextualizing Premodern Philosophy
This volume brings together contributions from distinguished scholars in the history of philosophy, focusing on points of interaction between discrete historical contexts, religions, and cultures found within the premodern period. The contributions connect thinkers from antiquity through the Middle Ages and include philosophers from the three major monotheistic faiths—Judaism, Islam, and Christianity. By emphasizing premodern philosophy’s shared textual roots in antiquity, particularly the writings of Plato and Aristotle, the volume highlights points of cross-pollination between different schools, cultures, and moments in premodern thought. Approaching the complex history of the premoder...
