Organic Solar Cells
Organic photovoltaic (OPV) cells have the potential to make a significant contribution to the increasing energy needs of the future. In this book, 15 chapters written by selected experts explore the required characteristics of components present in an OPV device, such as transparent electrodes, electron- and hole-conducting layers, as well as electron donor and acceptor materials. Design, preparation, and evaluation of these materials targeting highest performance are discussed. This includes contributions on modeling down to the molecular level to device-level electrical and optical testing and modeling, as well as layer morphology control and characterization. The integration of the different components in device architectures suitable for mass production is described. Finally, the technical feasibility and economic viability of large-scale manufacturing using fast inexpensive roll-to-roll deposition technologies is assessed.
Correlating structure and function in small molecule organic solar cells by means of scanning probe and electron microscopy
In this work nanoscale properties in active layers of small molecule organic solar cells are studied regarding their impact on device performance. For this, the effect of variations in stack design and process conditions is examined both electrically and with high resolution imaging techniques. Two topics are addressed: (i) the visualization of charge extraction/injection properties of solar cell contacts and (ii) the tailoring of structural properties of co-evaporated material blends for bulk heterojunction (BHJ) organic solar cells. (i) We study the impact of controlled contact manipulation on the internal electric potential distribution of fluorinated zincphtalocyanine (F4ZnPc)/fullerene ...
Organic Materials and Devices for Sustainable Energy Systems:
The continued expansion of organic electronics is driven by the cross-disciplinary expertise of both academic and industrial researchers. This synergy has led to significant advances in the fundamental understanding of these materials, as well as improvements in the efficiency and operational stability of organic electronic and optoelectronic devices. Many of these systems are being actively developed as part of next-generation, energy-efficient displays and solid-state lighting fixtures, as well as in photovoltaics for lost-cost solar energy utilization. To fully capitalize on these unique devices, significant gaps in fundamental understanding, as well as nontrivial technological challenges, must be overcome. This book brings together the academic and industrial communities to share recent advances in the field. Topics include device physics, development and characterization of new materials and device architectures, and novel processing methods. An important theme of the volume is the continuing pursuit of more efficient and longer-lived organic solar cells for commercial application.
Principles Of Solar Cells: Connecting Perspectives On Device, System, Reliability, And Data Science
How does a solar cell work? How efficient can it be? Why do intricate patterns of metal lines decorate the surface of a solar module? How are the modules arranged in a solar farm? How can sunlight be stored during the day so that it can be used at night? And, how can a lifetime of more than 25 years be ensured in solar modules, despite the exposure to extreme patterns of weather? How do emerging machine-learning techniques assess the health of a solar farm? This practical book will answer all these questions and much more.Written in a conversational style and with over one-hundred homework problems, this book offers an end-to-end perspective, connecting the multi-disciplinary and multi-scale...
