Solar To Chemical Energy Conversion

This book explains the conversion of solar energy to chemical energy and its storage. It covers the basic background; interface modeling at the reacting surface; energy conversion with chemical, electrochemical and photoelectrochemical approaches and energy conversion using applied photosynthesis. The important concepts for converting solar to chemical energy are based on an understanding of the reactions’ equilibrium and non-equilibrium conditions. Since the energy conversion is essentially the transfer of free energy, the process are explained in the context of thermodynamics.

This comprehensive book systematically covers the fundamentals in solar energy conversion to chemicals, either fuels or chemical products. It includes natural photosynthesis with emphasis on artificial processes for solar energy conversion and utilization. The chemical processes of solar energy conversion via homogeneous and/or heterogeneous photocatalysis has been described with the mechanistic insights. It also consists of reaction systems toward a variety of applications, such as water splitting for hydrogen or oxygen evolution, photocatalytic CO2 reduction to fuels, and light driven N2 fixation, etc. This unique book offers the readers a broad view of solar energy utilization based on chemical processes and their perspectives for future sustainability.

The intense current interest in the development of solar energy as a viable energy alternative comes as no surprise in view of the widespread awareness of impending world-wide energy shortages. After all, the magnitude of energy available from the sun is impressive, its diffuseness and intermittent nature notwithstanding. The fact that, as a source, it represents a constant and inex haustible supply of energy is alluring. The fact that most solar application schemes are nonpolluting in nature is an attractive bonus. In spite of these impressive attributes, research and development in the area of solar energy is in its infancy, owing largely to the prior lack of any need to exploit such diffuse sources. Indeed efforts in this area have traditionally been within the province of solid-state physics and engineering. The problems associated with efficient light harvesting and storage, however, are not simply technological ones. Effec tive solutions to these problems appear to lie beyond the current forefront of the chemical sciences. Consequently input fr9m scientists previously engaged in fundamental chemistry has begun to emerge. Thus many of the contributions in this volume represent input from research groups with a relatively short history of involvement in solar energy. On the other hand, the long-standing and perceptive commitment of Professor Melvin Calvin to research involving solar energy represents the other extreme. This volume covers a variety of approaches to the problem of efficiently converting and storing solar energy.

Finally filling a gap in the literature for a text that also adopts the chemist's view of this hot topic, Professor Likhtenshtein, an experienced author and internationally renowned scientist, considers different physical and engineering aspects in solar energy conversion. From theory to real-life systems, he shows exactly which chemical reactions take place when converting light energy, providing an overview of the chemical perspective from fundamentals to molecular harvesting systems and solar cells. This essential guide will thus help researchers in academia and industry better understand solar energy conversion, and so ultimately help this promising, multibillion dollar fi eld to expand.

Solar energy conversion requires a different mind-set from traditional energy engineering in order to assess distribution, scales of use, systems design, predictive economic models for fluctuating solar resources, and planning to address transient cycles and social adoption. Solar Energy Conversion Systems examines solar energy conversion as an integrative design process, applying systems thinking methods to a solid knowledge base for creators of solar energy systems. This approach permits different levels of access for the emerging broad audience of scientists, engineers, architects, planners, and economists. Traditional texts in solar energy engineering have often emerged from mechanical or chemical engineering fields. Instead, Solar Energy Conversion Systems approaches solar energy conversion from the perspectives of integrative design, environmental technology, sustainability science, and materials science in the wake of amazing new thin films, polymers, and glasses developed by the optoelectronics and semiconductor industries. This is a new solar text for the new generation of green job designers and developers. It’s highlighted with vignettes that break down solar conversion into useful stories and provides common points of reference, as well as techniques, for effective estimation of evolving technologies. Contextualizes solar conversion for systems design and implementation in practical applications Provides a complete understanding of solar power, from underlying science to essential economic outcomes Analytical approach emphasizes systems simulations from measured irradiance and weather data rather than estimations from "rules of thumb" Emphasizes integrative design and solar utility, where trans-disciplinary teams can develop sustainable solar solutions that increase client well-being and ecosystems services for a given locale

MATERIALS FOR SOLAR ENERGY CONVERSION This book provides professionals and students with a resource on the basic principles and applications of solar energy materials and processes, as well as practicing engineers who want to understand how functional materials operate in solar energy conversion systems. The demand for energy is increasing daily, and the development of sustainable power generation is a critical issue. In order to overcome the energy demand, power generation through solar energy is booming. Many research works have attempted to enhance the efficiency of collection and storage of solar energy and, as a result, numerous advanced functional materials have been developed for enhancing the performance of solar cells. This book has compiled and broadly explores the latest developments of materials, methods, and applications of solar energy. The book is divided into 2 parts, in which the first part deals with solar cell fundamentals and emerging categories, and the latter part deals with materials, methods, and applications in order to fill the gap between existing technologies and practical requirements. The book presents detailed chapters including organic, inorganic, coating materials, and collectors. The use of modern computer simulation techniques, conversion and storage processes are effectively covered. Topics such as nanostructured solar cells, battery materials, etc. are included in this book as well. Audience The book is aimed at researchers in materials science, chemistry, physics, electrical and mechanical engineering working in the fields of nanotechnology, photovoltaic device technology, and solar energy.

Photochemical Conversion and Storage of Solar Energy contains the proceedings of the Third International Conference on Photochemical Conversion and Storage of Solar Energy held in Boulder, Colorado, on August 3-8, 1980. The papers review the state of the art in the areas of photochemistry and photoelectrochemistry in the context of solar energy conversion and storage. Topics covered include photosynthetic quantum conversion; biomimetic systems for solar energy conversion; and photochemical electron transfer reactions in homogeneous solutions. This volume is comprised of 11 chapters and begins by describing an artificial photosynthetic system that can capture solar quanta and convert them into a stable chemical form. The discussion then turns to biomimetic approaches to solar energy conversion; fluorescent concentrators for photovoltaic cells; requirements for homogeneous photoredox chemistry in inorganic systems; and the use of inorganic components coupled with catalysts in heterogeneous assemblies for photochemical water splitting. The following chapters focus on photogalvanic cells, electrochemical photovoltaic cells, and photoelectrosynthetic reactions at the semiconductor-electrolyte interface. The final chapter examines the thermodynamic limits on photoconversion and storage of solar energy. This monograph will be of interest to chemists and other scientists concerned with the photochemical aspects of solar energy conversion and storage.
