Surface passivation of silicon solar cells describes a technology for preventing electrons and holes to recombine prematurely with one another on the wafer surface. It increases the cell's energy conversion efficiencies and thus reduces the cost per kWh generated by a PV system. In the past few years, new tools have been developed to ensure low cost of ownership for high volume production of passivated silicon solar cells. Different deposition techniques (ALD, PECVD, APCVD) and different materials (SiO2, Al2O3, Si3N4) have been tested during the development process of more than 10 years. Now, the silicon solar cell manufacturing industry is picking up the concept of rear side passivation. The next generation silicon solar cells in production will be the PERC (Passivated Emitter and Rear Cell) type using all the reported achievements including novel tool concepts and process technologies. This timely overview of silicon solar cell surface passivation, written by the leading experts in the field, is a key read for students and researchers working with silicon solar cells, as well as solar cell manufacturers.

Chemistry is considered to be one of the prime causes of environmental pollution and degradation. The United Nations General Assembly also addressed the environmental challenges in its Sustainable Development Goals (SDGs), which have been adopted in 2015. A closer look shows that to meet these goals chemistry will play an important role. Green chemistry encompasses design and synthesis of environmentally benign chemical processes, green approaches to minimize and/or remediate environmental pollution, the development of biomaterials, biofuel, and bioenergy production, biocatalysis, and policies and ethics in green chemistry. When products in use today become waste, we need to treat that waste so that hazardous substances are not re-circulated into new products. In this context, circular economy is also an important point of discussion, which focuses on recycling, reuse and use of renewable sources. The theme of the International Conference on "Green Chemistry in Environmental Sustainability & Chemical Education (ICGC-2016) held in Delhi from 17-18 November 2016 was to discuss the emerging green trends in the direction of sustainability and environmental safety. ICGC-2016 consisted of keynote, plenary and invited lectures, panel discussion, contributed oral papers and poster presentations. The conference provided a platform for high school students, undergraduate and postgraduate students, teaching fraternity and young researchers to interact with eminent scientists and academicians from all over the world who shared their valuable views, experience and research on the harmonious methods in chemistry for a sustainable environment.

This book offers a revealing picture of the myths and realities of the energy world by one of our most renowned energy experts and managers. At the end of the first decade of the 21st century, the human race finds itself caught in an "energy trap." Carbon-rich fossil fuels—coal, petroleum and natural gas—are firmly entrenched as the dominant sources of our energy and power. Their highly concentrated forms, versatility of use, ease of transport and storage, ready availability, and comparatively low costs combine to give fossil fuels an unassailable competitive advantage over all alternative sources of energy. This economic reality means that fossil fuels will inevitably continue to be the backbone of the global economy for the next quarter of a century, even while the adverse climate and environmental effects of our dependence on fossil fuels hurtle toward global crisis levels. To avert unacceptable environmental consequences, the world must deliberately and incrementally supplant fossil fuels with alternative energy sources, on a schedule that will have them overtake fossil fuels in the world's energy budget by 2035. To achieve this urgent goal without massive economic dislocation and reduction in standards of living, global investment in fossil fuel efficiency will be just as important as the development and massive deployment of alternative energy technologies and delivery systems. In this eagerly awaited sequel to his prize-winning bestseller, The Age of Oil, Leonardo Maugeri, the strategy director of one of the world's biggest energy companies, puts forward a hard-headed, concrete plan in simple everyday language for how to shift the world economy's primary energy dependence from fossil fuels to renewable energies by 2035. Assuming no specialized knowledge, the author walks the reader chapter by chapter through each of the fossil fuels (oil, coal, and natural gas) and each of the alternative energy sources (nuclear, hydroelectric, biofuel, wind, solar, geothermal, and hydrogen). Drawing on the unparalleled data and analysis resources at his command, Maugeri assesses the problems and advantages of each energy source in turn in order to constrain the optimal mix of energy sources that the world should be aiming for in 2035. Critically, he lays out the arduous path for getting from here to there. Maugeri shows that the next 25 years will be a rocky marriage between the old and the new energy paradigms, during which we must dramatically improve the efficiency of our continuing use of fossil fuels, while driving ahead on all fronts to an energy future based on a suite of sustainable energy sources.

Fault Diagnosis and Sustainable Control of Wind Turbines: Robust Data-Driven and Model-Based Strategies discusses the development of reliable and robust fault diagnosis and fault-tolerant ('sustainable') control schemes by means of data-driven and model-based approaches. These strategies are able to cope with unknown nonlinear systems and noisy measurements. The book also discusses simpler solutions relying on data-driven and model-based methodologies, which are key when on-line implementations are considered for the proposed schemes. The book targets both professional engineers working in industry and researchers in academic and scientific institutions. In order to improve the safety, reliability and efficiency of wind turbine systems, thus avoiding expensive unplanned maintenance, the accommodation of faults in their early occurrence is fundamental. To highlight the potential of the proposed methods in real applications, hardware-in-the-loop test facilities (representing realistic wind turbine systems) are considered to analyze the digital implementation of the designed solutions. The achieved results show that the developed schemes are able to maintain the desired performances, thus validating their reliability and viability in real-time implementations. Different groups of readers-ranging from industrial engineers wishing to gain insight into the applications' potential of new fault diagnosis and sustainable control methods, to the academic control community looking for new problems to tackle-will find much to learn from this work.

With energy consumption rising and with it our dependence on crude oil from politically uncertain regions, and faced with the threat to the environment from polluting emissions, it is becoming ever more evident that fuels from renewable resources are an increasingly attractive option to fossil fuels. Edinger and Kaul, like a growing number of other experts, hold the mobility of populations--transportation, in other words--responsposible for the rise in the rate of greenhouse gas emissions, a condition that can only get worse as less developed regions of the world emerge with their own needs and demands for mobility. What to do? Edinger and Kaul outline in sharp detail the shortcomings of current vehicular technologies and dominant fossil fuels. They present a careful, authoritative examination of innovative technologies that in their opinion have the best chance of combating dangerous reliance on conventional means of power, not only for transportation but other purposes as well. And they focus on special forms of fuel cell drive systems, with their high efficiencies and reduced consumptions, and on other emerging renewable technologies and their innovative, sustainable power sources--such as fuels from biomass and renewable electricity, a particularly promising source of energy for newly growing economies. Wide ranging in coverage, forthright in style, the book is an important review of how things are today, why they could get worse, but perhaps most importantly, what we can do about it.
