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.

The purpose of this book is to review the current state of this quickly developing field. Up until now, there has been no concise review available of the rather diverse aspects of this field. This book gives a basic introduction to the concepts behind Bloch oscillations. It describes how the physics of high field transport has been investigated through a broad range of experimental techniques such as interband and intraband optical spectroscopy and transport experiments. Possible applications and further trends are also discussed.

Unter den bis heute wichtigen historischen Wurzeln einer europaischen Kultur nimmt die Geschichte der Juden eine besondere Stellung ein. In den Quellen, die in diesem Buch prasentiert werden, stellen sich die Juden als keineswegs hilflos der christlichen Gesellschaft ausgeliefert dar. Die Wirklichkeit scheint von grosser Lebenskraft vieler Gemeinden bestimmt gewesen zu sein. Als Grundzug der hier behandelten Epoche judischer Geschichte in der Spatantike zeigt sich, dass die mehrheitlich christliche Judentheologie und die Realitat des Lebens zum Teil weit auseinanderfielen. Dies aber machte die Lage der Juden instabil und unberechenbar."

Das moderne Europa ruht auf dem Erbe der klassischen Antike und des Christentums. Beide Wurzeln sind eng miteinander verwoben. "Neues Testament und Antike Kultur" (NTAK) entfaltet die unterschiedlichen EinflA"sse und Wechselbeziehungen zwischen diesen beiden GrAAen. Denn wer das Neue Testament verstehen will, muss die Welt kennen, in der es entstanden ist. Dabei soll das Neue Testament bewusst nicht als FremdkArper, sondern als Teil antiker Kultur dargestellt werden. Weil Religion, Gesellschaft und Kultur in der antiken Welt eine Einheit bilden, ist interdisziplinAre Zusammenarbeit der einzige Weg ihrer Erforschung. Nur so kann auch das Eigene eines jeden Themas sachgemAA erfasst werden. Ausgewiesene Fachleute aus den unterschiedlichsten Disziplinen und zahlreichen LAndern tragen in einem interkonfessionellen Ansatz ihre Erkenntnisse in mehr als 170 Artikeln zum Spannungsfeld von Neuem Testament und Antiker Kultur bei.
