Book Description
Organic photovoltaic is an attractive technology to solve future energy supply scenarios. To further increase the potential of this technology novel absorber materials and interface materials have to be developed. In this work the paramount importance of interface materials for efficient as well as stable organic photovoltaic cells and modules is demonstrated. The general requirements of interface materials are elaborated and properties of a novel interface material which meets the demands are investigated experimentally and by simulations.

Book Description
This book presents an important technique to process organic photovoltaic devices. The basics, materials aspects and manufacturing of photovoltaic devices with solution processing are explained. Solution processable organic solar cells - polymer or solution processable small molecules - have the potential to significantly reduce the costs for solar electricity and energy payback time due to the low material costs for the cells, low cost and fast fabrication processes (ambient, roll-to-roll), high material utilization etc. In addition, organic photovoltaics (OPV) also provides attractive properties like flexibility, colorful displays and transparency which could open new market opportunities. The material and device innovations lead to improved efficiency by 8% for organic photovoltaic solar cells, compared to 4% in 2005. Both academic and industry research have significant interest in the development of this technology. This book gives an overview of the booming technology, focusing on the solution process for organic solar cells and provides a state-of-the-art report of the latest developments. World class experts cover fundamental, materials, devices and manufacturing technology of OPV technology.

Book Description
A major global issue that the world is facing today is the upcoming depletion of fossil fuels and the energy crisis. In 1998, the global annual energy consumption was 12. 7 TW; of which 80% was generated from fossil fuels. This also translates into huge annual emissions of CO that leads to massive environmental problems, 2 particularly the global warming, which could be disastrous. Future global annual energy needs are also estimated to rise dramatically. A major challenge confronting the world is to ?nd an additional 14–20 TW by 2050 when our energy reserves based on fossil fuels are vanishing. The massive demand for energy would require materials and/or processes that would help to provide new sources of clean ren- able energy or to develop processes that would harvest energy or to better utilize energy in an ef?cient manner. The present monograph, WOLEDs and Organic Photovoltaics – Recent Advances and Applications, focuses on a very important and timely subject of topical interest that deals with the more ef?cient use of energy through white organic light-emitting diodes (WOLEDs) for solid-state lighting and the development of clean sources of renewable energy through the harvesting of light energy for conversion into electrical energy in organic photovoltaics. While LED solid-state lighting and photovoltaics have been dominated by inorganic semiconductor materials and silicon-based solar cells, there have been growing interests in the development of WOLEDs and organic photovoltaics.

Book Description
Recently developed organic photovoltaics (OPVs) show distinct advantages over their inorganic counterparts due to their lighter weight, flexible shape, versatile materials synthesis and device fabrication schemes, and low cost in large-scale industrial production. Although many books currently exist on general concepts of PV and inorganic PV materials and devices, few are available that offer a comprehensive overview of recently fast developing organic and polymeric PV materials and devices. Organic Photovoltaics: Mechanisms, Materials, and Devices fills this gap. The book provides an international perspective on the latest research in this rapidly expanding field with contributions from top experts around the world. It presents a unified approach comprising three sections: General Overviews; Mechanisms and Modeling; and Materials and Devices. Discussions include sunlight capture, exciton diffusion and dissociation, interface properties, charge recombination and migration, and a variety of currently developing OPV materials/devices. The book also includes two forewords: one by Nobel Laureate Dr. Alan J. Heeger, and the other by Drs. Aloysius Hepp and Sheila Bailey of NASA Glenn Research Center. Organic Photovoltaics equips students, researchers, and engineers with knowledge of the mechanisms, materials, devices, and applications of OPVs necessary to develop cheaper, lighter, and cleaner renewable energy throughout the coming decades.

Book Description
Dramatic improvements in organic photovoltaic device efficiency can be obtained by optimizing spectral absorbance and frontier molecular orbital (FMO) energies, increasing solid state exciton/charge mobility, and utilizing p-/n-type nanoarchitecture. Combining all of these properties into a new material presents a considerable synthetic challenge because potential commercial applications require materials that are high-performance and inexpensive. Thus, it is advantageous to design new materials using a versatile, modular synthetic approach that allows each design criterion to be engineered individually, in a synthetically efficient manner. Several strategies were successfully pursued using simple interchangeable electron donor and acceptor components as functional modules, which provided various donor-acceptor chromophores in a synthetically straightforward manner. This approach provided broad functional tunability to the range of materials produced and, as a result, various molecular engineering requirements were systematically addressed. In some cases, these materials were utilized in photovoltaic devices as p-type active layers or redox enhancement additives. In these cases, competitive power conversion efficiencies were obtained or test device performance was considerably enhanced by comparison to control devices. Fluorenone, fluorenylidene-malononitrile, and squaric acid were utilized as electron acceptor modules, and electron donor module strength was varied using a styrene-based and several di- and triarylamine-based components. One strategy, published in Phys. Chem. Chem. Phys., (Chapter 2, DOI-10.1039/C2CP41813D) is to fix the donor-acceptor lowest unoccupied molecular orbital energy using the synthetically versatile fluorenone module. Fluorenone was chosen because of its ready availability and synthetic versatility, and its multiple functionalization sites allow for selective FMO engineering. Extrapolation of this approach was published in J. Phys. Chem. A. (Chapter 3, DOI-10.1021/jp407854r), describing various fluorenylidene-malononitrile derivatives. Chemical oxidation of fluorenone-based triarylamines to produce stable radicals was published in Tetrahedron Letters (Chapter 4, DOI-10.1016/j.tetlet.2012.10.060). Fluorenone derivatives applied as dye sensitized solar cell redox system enhancement additives was described in RSC Advances (Chapter 5, DOI-10.1039/C3RA40986D). Development of new, functionalized, squaraine-based materials was described in J. Phys. Chem. C. (Chapter 6, DOI-10.1021/jp410362d) and was extrapolated for use in single-heterojunction photovoltaic cells having 4.8% maximum power conversion efficiency. The fundamental insights provided by these findings will be valuable for developing new high-performance photovoltaic materials in the future.

Book Description
This book presents an original investigation into alternative photovoltaic absorbers. Solar power is a highly promising renewable energy solution; however, its success is hampered by the limited cost-effectiveness of current devices. The book assesses the photovoltaic performance of over 20 materials using state-of-the-art, first-principles methods. Adopting a computational approach, it investigates atomic-scale properties at a level of accuracy that is difficult to achieve using laboratory-based experimental techniques. Unlike many theoretical studies, it provides specific advice to those involved in experimental investigations. Further, it proposes directions for future research. This book advances the field of photovoltaics in three crucial ways: firstly, it identifies why one class of proposed materials cannot achieve high efficiency, while at the same time gaining insights that can be used to design future absorbers. Secondly, it shows that poor performance in the bismuth chalcohalides is not due to fundamental limitations, and can be overcome by finely controlling synthesis conditions. Lastly, it describes a range of new stable materials that are expected to show excellent photovoltaic performance.
