Download or read book Photon Management in Solar Cells written by Ralf B. Wehrspohn and published by John Wiley & Sons. This book was released on 2016-03-09 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by renowned experts in the field of photon management in solar cells, this one-stop reference gives an introduction to the physics of light management in solar cells, and discusses the different concepts and methods of applying photon management. The authors cover the physics, principles, concepts, technologies, and methods used, explaining how to increase the efficiency of solar cells by splitting or modifying the solar spectrum before they absorb the sunlight. In so doing, they present novel concepts and materials allowing for the cheaper, more flexible manufacture of solar cells and systems. For educational purposes, the authors have split the reasons for photon management into spatial and spectral light management. Bridging the gap between the photonics and the photovoltaics communities, this is an invaluable reference for materials scientists, physicists in industry, experimental physicists, lecturers in physics, Ph.D. students in physics and material sciences, engineers in power technology, applied and surface physicists.

Download or read book Photon Management Assisted by Surface Waves on Photonic Crystals written by Angelo Angelini and published by Springer. This book was released on 2017-01-16 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates original pathways to manipulate light at the nanoscale by means of surface electromagnetic waves (here, Bloch surface waves, BSWs) on planar dielectric multilayers, also known as one-dimensional photonic crystals. This approach is particularly valuable as it represents an effective alternative to the widely exploited surface plasmon paradigm. After a brief overview on the fundamentals of BSWs, several significant applications of BSW-sustaining structures are described. Particular consideration is given to the propagation, guiding, and diffraction of BSW-coupled radiation. Further, the interaction of organic emitters with BSWs on planar and corrugated multilayers is investigated, including fluorescence beaming in free space. To provide greater insight into sensing applications, an illustrative example of fluorescent microarray-based detection is presented. The book is intended for scientists and researchers working on photon management opportunities in fields such as biosensing, optical circuitry, and lighting.

Download or read book Micro and Nanophotonics for Semiconductor Infrared Detectors written by Zoran Jakšić and published by Springer. This book was released on 2014-09-25 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of microelectromechanic system (MEMS) technologies and nanotechnologies has resulted in a multitude of structures and devices with ultra compact dimensions and with vastly enhanced or even completely novel properties. In the field of photonics it resulted in the appearance of new paradigms, including photonic crystals that exhibit photonic bandgap and represent an optical analog of semiconductors and metamaterials that have subwavelength features and may have almost arbitrary values of effective refractive index, including those below zero. In addition to that, a whole new field of plasmonics appeared, dedicated to the manipulation with evanescent, surface-bound electromagnetic waves and offering an opportunity to merge nanoelectronics with all-optical circuitry. In the field of infrared technologies MEMS and nanotechnologies ensured the appearance of a new generation of silicon-based thermal detectors with properties vastly surpassing the conventional thermal devices. However, another family of infrared detectors, photonic devices based on narrow-bandgap semiconductors, has traditionally been superior to thermal detectors. Literature about their micro and nanophotonic enhancement has been scarce and scattered through journals. This book offers the first systematic approach to numerous different MEMS and nanotechnology-based methods available for the improvement of photonic infrared detectors and points out to a path towards uncooled operation with the performance of cryogenically cooled devices. It is shown that a vast area for enhancement does exists and that photonic devices can readily keep their leading position in infrared detection. The various methods and approaches described in the book are also directly applicable to different other types of photodetectors like solar cells, often with little or no modification.

Book excerpt: Wolf's contributions to optical physics go far beyond his co-writing, with Max Born, the classic Principles of Optics. He introduced spatial coherence, he was the first to describe Gabor's holography, and his work has served as the foundation of about 250 companies and corporate divisions in the English-speaking world. In these 23 essays, two of which are tributes to the life of Wolf, contributors consider aspects of his work such as the polarization of light, the electromagnetic theory of optical coherence, wave descriptions of optical measurements, holographic microscopy, optical physics and psychology, the Wolf effect and the Wolf shift, optical pathlength spectroscopy, the diffractive multifocal focusing effect, phase and information, holography, internal reflection tomography, and nano- optics.

Book excerpt: 2015 is the International Year of Light. While we celebrate past and present triumphs of light sciences, our society is undergoing an inevitable and far-reaching transition from indirect, inefficient, and non-renewable to direct, efficient, and renewable methods to utilize the energy from sunlight. Fossil fuels allow us to use solar energy captured by ancient biological materials, which did not necessarily evolve to maximize the energy harvesting efficiency. As we continue to deprive the natural resources, they will be increasingly too costly to recover and too valuable to burn, not to mention present and future environmental externalities. The optimal method to harvest the abundant solar energy consists of using solar cells, which absorb sunlight in semiconductors and convert the photon energy to more easily usable forms. With an array of maturing technologies such as concentration, storage, and smart grid, the solar industry is expected to grow substantially at least in the long run. An optoelectronic device, the solar cell requires photon management for efficiency enhancement and cost reduction, both of which are critical for any commercial success. With these objectives in mind, this dissertation concerns the optimal use of photonic methods for the improvement of optical and electronic performances of solar cells.

Download or read book Advanced Concepts in Photovoltaics written by Arthur J. Nozik and published by Royal Society of Chemistry. This book was released on 2014-07-10 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photovoltaic systems enable the sun’s energy to be converted directly into electricity using semiconductor solar cells. The ultimate goal of photovoltaic research and development is to reduce the cost of solar power to reach or even become lower than the cost of electricity generated from fossil and nuclear fuels. The power conversion efficiency and the cost per unit area of the phototvoltaic system are critical factors that determine the cost of photovoltaic electricity. Until recently, the power conversion efficiency of single-junction photovoltaic cells has been limited to approximately 33% - the so-called Shockley-Queisser limit. This book presents the latest developments in photovoltaics which seek to either reach or surpass the Shockley-Queisser limit, and to lower the cell cost per unit area. Progress toward this ultimate goal is presented for the three generations of photovoltaic cells: the 1st generation based on crystalline silicon semiconductors; the 2nd generation based on thin film silicon, compound semiconductors, amorphous silicon, and various mesoscopic structures; and the 3rd generation based on the unique properties of nanoscale materials, new inorganic and organic photoconversion materials, highly efficient multi-junction cells with low cost solar concentration, and novel photovoltaic processes. The extent to which photovoltaic materials and processes can meet the expectations of efficient and cost effective solar energy conversion to electricity is discussed. Written by an international team of expert contributors, and with researchers in academia, national research laboratories, and industry in mind, this book is a comprehensive guide to recent progress in photovoltaics and essential for any library or laboratory in the field.
