Limited availability of grid-based electricity is a major challenge faced by many developing countries, particularly the rural population. Fuel-based lighting, such as the kerosene lantern, is widespread in these areas, but it is a poor alternative, contributing to global warming and causing serious health problems. Several developing countries are therefore now encouraging the use of sustainable lighting. Solar Lighting gives an in-depth analysis of energy-efficient light production through the use of solar-powered LED systems. The authors pay particular attention to the interplay between energy transformation and device efficiency. They also discuss diverse aspects of renewable energy, including how an improvement in the efficiency of appliances can reduce the cost of energy. Solar Lighting is written for physicists, environmental experts and lighting engineers. It is also suitable for undergraduate students in the fields of environmental science, electrical engineering and renewable energy.

Howard Teich has discovered a brilliantly simple and invaluable way of helping men and women move towards wholeness and healing. With vivid examples from his therapeutic practice and from his own life, Solar Light, Lunar Light presents Teich's pioneering development of the solar/lunar polarity, and his sharp distinction of this from the masculine/feminine polarity with which it has long been uncritically and often destructively conflated. Recognizing this distinction, and moving towards a deep integration and rebalancing of the solar and lunar principles, represents a crucial task not only for every individual but for our civilization. --Richard Tarnas, Professor of Philosophy and Psychology, California Institute of Integral Studies, Author of The Passion of the Western Mind and Cosmos and Psyche--- This is a significant, life changing book. Howard Teich's work is crucial to understanding and healing the damage our rigid ideas of gender have done to us all, women and men alike. This is a book that can change how you see every problem you encounter and point you toward deeper more creative responses. Here is a psychology that has the potential of restoring us all and our world to wholeness. ---Susan Griffin, author of A Chorus of Stones and Woman and Nature--- The perception that masculine and feminine traits represent oppositional forces has contributed to a long history of personal and cultural dysfunctions. Through a skillful interweaving of modern psychology, mythology and ancient history, Howard Teich, PhD offers a thought provoking thesis that these polarizing traits are actually cooperative partners in evolution s dynamic dance. Solar Light, Lunar Light is a healing journey that encourages readers to transcend misperceived limitations so that we may write a new empowering chapter in human evolution. --Bruce H. Lipton, Ph.D., Cell biologist and bestselling author of The Biology of Belief: Unleashing the Power of Consciousness, Matter and Miracles.

Solar Cells and Light Management: Materials, Strategies and Sustainability provides an extensive review on the latest advances in PV materials, along with light management strategies for better exploiting the solar spectrum. Following a brief review of the current status of solar cells, the book discusses different concepts, principles and technologies for solar devices, starting with standard silicon cells and then covering organic-hybrid, DSSC, perovskite, quantum dots and nanostructured oxide solar cells. Other sections focus on light manipulation and spectral modification, materials for spectral conversion, and environmental and sustainably considerations. An emergy analysis, which is an extension of the Life Cycle Assessment methodology, is applied to the study of solar PV systems, thus allowing for effective integrated indicators.

This book explains the use of nanocrystalline semiconductors in the harvesting of energy from solar light. It introduces promising methodology and technology which may help to increase the efficiency of light harvesting – one of the major challenges on the way toward sustainable energy generation.The book starts with a general introduction to the photochemistry of semiconductor nanocrystals. In the introductory chapter, the author also provides a frank and critical discussion on perspectives and limitations of the photocatalytic processes for solar light conversion including a historical account on semiconductor photocatalysis. He discusses that (and also why) it is a long way from laboratory prototypes to real sustainable technologies.The following chapters outline the conversion of solar light energy in semiconductor nanophotocatalysis on the one hand, and to (electric) energy in nanocrystalline semiconductor-based solar cells on the other hand. Topics addressed include nanophotocatalytic hydrogen production, artificial photosynthesis, quantum-dot sensitized liquid-junction and bulk heterojunction solar cells. Perspectives and opportunities, but also bottlenecks and limitations are discussed and the novel systems compared with established technology, such as classical silicon solar cells. While readers in this way learn to understand the basics and get introduced to the current research in the field, the final chapter provides them with the necessary knowledge about methodology, both in synthesis and characterization of semiconductor nanophotocatalysts and semiconductor nanomaterials, including examples for the practice of photocatalytic experiments and the studies of semiconductor-based solar cells.

This book highlights the promising photocatalytic methods for synthesizing organic chemicals by simultaneously degrading the toxicity of raw substances used for organic synthesis. It presents various semiconducting materials with high catalytic activities in hydrogen evolution reactions (HERs) and hydrogenation reactions, as well as the material characterizations for identifying semiconductor photocatalysts. The focus is on understanding the hydrogen dissociation and activation of substances in the process of hydrogenation and the fabrication of nanostructured catalysts with desired activity and selectivity. Recent works show photocatalytic hydrogenation reactions with in situ generated H+ on catalyst surfaces utilizing initial chemicals such as nitrophenol, nitrobenzene, azobenzene, and benzene for valorization. In addition, the photocatalytic valorization of waste glycerol is also discussed. Besides the hydrogenation reactions, the reduction of oxygen to form H2O2 can be done with a photocatalytic method in atmospheric conditions. Some related perspectives and outlooks are also discussed for possible future development.
