PEROVSKITE MATERIALS FOR ENERGY AND ENVIRONMENTAL APPLICATIONSThe book provides a state-of-the-art summary and discussion about the recent progress in the development and engineering of perovskite solar cells materials along with the future directions it might take.Among all 3rd generation solar cells, perovskite solar cells have recently been attracting much attention and have also emerged as a hot research area of competing materials for silicon PV due to their easy fabrication, long charge-carrier lifetime, low binding energy, low defect density, and low cost.This book focuses primarily on the perovskite structures and utilizes them in modern technologies of photovoltaics and environmental applications. It will be unique in terms of the use of perovskite structures in solar cell applications. This book also discusses the type of perovskites, their synthetic approach, and environmental and solar cell applications. The book also covers how perovskite solar cells originated and the recent advances in perovskite solar cells.The reader will find in this book a lucid account that:* Introduces the history of perovskite materials.* Explores perovskite materials for energy conversion and environmental-related applications.* Covers perovskite light absorber materials for the fabrication of high-performance perovskite solar cells.* Describes the device architectures and physics of perovskite solar cells.* Discusses the role of perovskite absorber, electron transport, and hole transport materials layers.AudienceThe book is essential reading for all those in the photovoltaic community, including materials scientists, surface physicists, surface chemists, solid-state physicists, solid-state chemists, and electrical engineers.

Plant Metabolites and Regulation Under Environmental Stress presents the latest research on both primary and secondary metabolites. The book sheds light on the metabolic pathways of primary and secondary metabolites, the role of these metabolites in plants, and the environmental impact on the regulation of these metabolites. Users will find a comprehensive, practical reference that aids researchers in their understanding of the role of plant metabolites in stress tolerance.

The rapid change in the agro-ecosystem leaves a snag in the establishment of harmony the discard of the disturb ecosystem due to wide usage of chemical pesticides, fertilizers, and synthetic plant growth regulators. The long term effect were overlooked hence, boom of one time become bane for the ecosystem degradation. At the present context, it has become indispensable to look for sustainable crop protection management approaches for disease management and the present book is an effort to this direction. The diseases of economic importance caused by fungi, bacteria, viruses and virus like organisms of each crop are covered, describing their history, distribution, losses incurred, symptoms latest diagnostic tools, epidemiology and integrated applied management approaches including cultural, chemical, genetic resources, use of bio-control agents being adopted world-wide. The layout of each chapter includes a brief introduction and pathogen-wise description of the diseases. Some chapters are vividly illustrated with photographs of typical symptoms, graphs, tables and line drawing to make the subject more interesting and easy to understand for students, Scientists, Planners, Administrators, Growers and other end users with latest pertinent references. The book contains recent information on IDM, Concepts and Practices in Integrated Plant Diseases Management, biological control, Emerging and threatening diseases of plants, detection, diagnosis, and management; Diseases of saffaron, Egg plant Chili, Maize, apple, minor millets, Cotton, Sunflower, chickpea, strawberry, Lentil Rust, chickpea, Plant disease management through resistance, Role of Nutrients in Plant Diseases Management, Nonpathogenic disorders in tomato and their management, Nonpathogenic diseases of potato tubers, Aflatoxins: Threats in food stuff, Characterization and Management of Papaya Ringspot Virus, Cloning, Sequencing and Transformation of Coat Protein Gene of Papaya Ringspot Virus, Eco- Management of Plant Diseases through Bio-agents, Eco-friendly Management of Fusarial Wilts of Vegetable and Fruit Crops.
